Car brakes are constantly being improved to enhance vehicle safety characteristics. They are one of the essential automotive systems in which manufacturers invest and develop. Drivers can be confident on every journey when brakes operate smoothly and effectively. Cars equipped with modern braking systems often have more competitive advantages in the market. Thus, this article will provide information on 5 types of car brakes commonly used in modern cars.

5 types of car brakes commonly used in today’s automobiles.

Brakes are mechanical devices that limit wheel movement by creating friction. As a result, car brakes in operation will help control speed or stop the vehicle at the driver’s discretion. In the early development of cars, brakes were merely logs attached to a wagon’s rims. The driver pushes the lever, and the wooden block will limit the wheel’s rotation speed. Later, to reduce heaviness, the wooden braking system was replaced with steel and leather.

However, they still did not provide the desired braking effect and caused annoying noises. The challenge for car manufacturers was the need to improve the braking system for safety, aesthetics, and to provide comfort for the driver. To date, modern cars are equipped with advanced braking systems to enhance usage safety.

For each type of car brake, there will be certain advantages and disadvantages. Therefore, to evaluate and compare which system is the best, we must base it on their pros and cons and compare them with our needs and control habits to choose the right type of brakes. Let’s explore the characteristics of these different brake types in detail in the next part of the article.

Drum Brakes

Drum brakes are commonly used on two or four-wheeled vehicles. Drum brakes on cars often use hydraulic brakes as they utilize hydraulic pressure to push the brake pads. When the driver presses the brake pedal, the pressure presses two brake shoes against the drum. This will create friction and cause your car to slow down and stop. Drum brakes include many components such as brake shoes, brake pads, linings, springs, brake drums, etc., which play different roles in the braking system.

• Brake Shoes: Made from die-cast aluminum, lightweight, and offering good heat dissipation. Brake shoes come in many different models and are made specifically for each model and year of manufacture. They are typically shaped like a circle with two semi-circular toes. This component is located in a part of the drum brake, but the brake shoe does not touch or come into direct contact with the drum.
• Wheel Cylinder: Functions as a chamber containing a piston and oil to transmit fluid pressure into mechanical movement.
• Return Spring: When the oil pressure decreases, the return spring forces the piston back to its original position.
• Piston: The part that is connected to the brake shoe. When there is oil pressure, this part will push, which forces the pads to press against the brake drum to help the vehicle stop.

Advantages:

• High durability, adapt to many different weather and terrain conditions thanks to the sealed design, avoiding environmental factors such as dirt.
• Save on maintenance, replacement, and installation costs.
• The brake drum has a simple structure, making it easy to disassemble. And, the cost is low.
• Ensure necessary safety; the car does not skid during braking.

Disadvantages:

• Compared to disc brakes, drum brakes have more weight and a slower deceleration time.
• The sealed design makes heat dissipation capacity poor, reducing braking performance, especially during urgent braking.

Disc Brakes

Possessing many exceptional advantages over drum brakes, disc brakes are equipped on the front wheels of many commercial vehicles. When drivers press the brake pedal, the oil pressure in the line and the wheel cylinder increases, pushing the piston and brake pads against the brake disc, creating friction and slowing the wheel.

So, what is its structure? A disc brake consists of 4 main parts: rotor, caliper, pad, and piston. This brake combination is designed to be open, and the components have flexible coordination, helping the car stop or reduce speed effectively.

• Rotor: Today, most rotors are made of carbon steel. It is a material with good heat resistance, good load-bearing capacity, and high durability.
• Caliper: Has the effect of holding and pressing the brake pads against the brake disc to generate sufficient braking force to help the vehicle decelerate and stop smoothly.
• Brake Pad: Brake pads are a unified block made from heat-resistant materials such as ceramic, metallic, and organic pads. This part of the car disc brake structure consists of 2 clamps that grip the brake disc.
• Piston: The working principle of disc brakes is to use specialized fluid to transmit force. When the piston is operating, it exerts pressure on the brake pads against the brake disc, helping the vehicle slow down or stop.

In addition to the 4 main parts above, disc brakes also have springs and air filters to help the disc brake system operate smoothly and efficiently. Besides using disc brakes on modern cars, most car manufacturers equip optimal braking assistance technology, such as anti-lock braking systems and brake force assistance systems.

Advantages:

• Deceleration efficiency is much higher than drum brakes due to greater friction force.
• The material is heat-resistant, has good bearing capacity, is durable, less prone to damage, and its weight is lighter than drum brakes.
• Disc brakes have an open structure to increase heat dissipation and water drainage. From there, performance is improved, and technicians can easily observe faults for cleaning and repair.

Disadvantages:

• Because the disc brake is designed to be exposed, it is easy for dust to stick, reducing efficiency after long-term use. Therefore, drivers must pay attention to cleaning them or taking them for regular maintenance to avoid damaging these parts.
• The friction between the pads and discs can cause noise while driving the vehicle.
• Disc brakes are made from high-quality materials to ensure vehicle safety. However, the maintenance and replacement cost of disc brakes is much higher than that of drum brakes.

Emergency Brakes

The emergency brake, also known as the parking brake, is mechanically operated and serves to keep the vehicle in place when parked. Even if the vehicle is parked on different slopes.

When there is poor friction between the tire and the road surface, the parking brake will prevent the wheels from moving. Depending on the driving factor and how it is controlled, the handbrake is divided into two types: mechanical and electronic. Each type has a different structure, working principle, and application.

Mechanical Handbrakes

They consist of a cable connected to the 2 rear wheels. When the driver pulls the brake, the cable acts on the rotating lever, converting the pulling force into pressing the brake shoes into the drum, limiting the wheel’s rotation to help your car stop. If the rear wheel uses a disc brake, the mechanical handbrake will use this mechanism to stop the vehicle.

Advantages:

• Low production cost due to simple design
• Easy to disassemble, repair in case of breakage
• Component lifespan is longer than that of electronic brakes.

Disadvantages:

• Occupies a large area of the car due to its bulky structure
• Many details and manipulations make it difficult for the driver to use
• Too high cost for periodic maintenance to avoid brake locking.

Electronic Handbrake

The electronic handbrake was invented later, possessing exceptional and more modern advantages, so it is commonly used. It has a structure consisting of a DC motor actuator mounted on the two rear wheels and an EPB (Electronic Parking Brake). The operation of the electronic handbrake is ensured by the electric motor. When you pull the brake, the electrical signal is transmitted to the electric motor of the rear wheels via the EPB to help the vehicle stop. Drivers must pay attention to pressing the brake pedal first, then pulling the control lever to activate the brake.

Advantages:

• The compact design saves a lot of space for the car.
• Simple operation with a modern structure.
• Avoid unnecessary accidents when the driver forgets to release the brake.
• Limiting the locking situation, brake locking occurs in mechanical brakes.

Disadvantages:

• When there is no more battery, the handbrake cannot function
• The brake pedal has a slight vibration when moving
• Component lifespan is lower

Anti-lock Brakes (ABS)

The ABS braking system is an active safety system common to most cars today. This system works to slow down, stop, and park the car when needed. When the car brakes suddenly on a slippery road, the phenomenon of wheel locking is likely to occur. This causes the wheel to skid on the road during braking, endangering drivers. Anti-lock brakes were developed to solve this problem. ABS helps reduce the risk of accidents through optimal braking control. The ABS braking system of a car is composed of parts: a speed sensor, a hydraulic valve, and a control system.

• Speed Sensor: The part that helps the ABS system detect whether the wheels are locked or not. These speed sensors are placed on each wheel or differential.
• Hydraulic Valve: A valve that controls the brake pads at each wheel. It will be located in 3 basic positions. Open valve (the force applied by the driver, the brake pressure will create the equivalent force directly transmitted to the wheel). Blocking valve (received brake pressure greater than the force applied by the driver). Release valve (received brake pressure less than the force applied by the driver).
• Control System: Receives the task of collecting information and data from speed sensors, then calculates and makes appropriate adjustments to the optimal brake pressure for each wheel.

Advantages:

• Cars equipped with an anti-lock system will operate particularly during braking on slippery roads or during emergency braking, ensuring the car’s stability during braking, giving the driver more time to handle the situation and protecting drivers.
• Optimize the space inside the cockpit, save space.
• Operations are also simpler and more convenient.

Disadvantages:

• Many people mistakenly believe that the main effect of ABS is to reduce braking distance. The reality is not like that.
• Higher production and repair costs due to modern technology and more complex features.
• Studies have also shown that ABS is not really effective on dry roads and has longer braking distances on snow.

Regenerative Braking System (RBS)

Regenerative braking is one of the modern technologies in the automotive industry. It is used in electric and hybrid vehicles, as well as some gasoline vehicles. RBS converts kinetic energy into electrical energy for cars, thereby helping to increase energy efficiency. On traditional car models, a large amount of energy is wasted if conventional braking is used. Because if the driver presses the brake pedal while the vehicle is moving. The braking surface is repelled by the friction of the drum or brake pads and completely wastes heat.

When braking a hybrid or EV, the electric motor switches to generator mode. The wheels transmit kinetic energy through the transmission to the “generator.” The generator converts a large portion of the kinetic energy into electrical energy, which is then stored in the vehicle’s high-voltage battery. At the same time, the resistance of the generator generating electricity will slow down the vehicle.

Of course, this braking process takes a long time until the car stops. Thus, when more braking torque is needed than the generator can provide. Additionally, braking is performed by friction.

Advantages:

• Increase energy efficiency: reduction in fuel consumption and CO2 emissions, especially in urban traffic situations involving frequent braking and acceleration.
• Reduce wear: during regenerative braking, when the motor no longer receives energy from the battery, it restarts the wheel’s rotation, using mechanical energy and returning energy to the storage battery. Therefore, reducing wear and extending brake life is evident.
• Not much heat loss: traditional braking systems apply friction to convert mechanical energy into heat. Thus, from an energy perspective, braking generates an amount of heat that cannot be reused. However, regenerative braking slows the vehicle in a very different way.
• Energy conservation: The flywheel absorbs energy during braking through a clutch system that reduces the vehicle’s speed and increases wheel rotation. For acceleration, another clutch system connects the flywheel to the transmission, increasing the vehicle’s speed and reducing the flywheel. Thus, energy is conserved by heat and light, which often occurs in the braking system simultaneously.

Disadvantages:

• Only effective during deceleration at very low speeds. Because the braking torque generated by the generator is not sufficient to stop the vehicle in a short time.
• The regenerative braking system has its own advantages when the car is moving in the city. However, the vehicle’s fuel consumption is even higher when driving on the highway.

In conclusion

The above is a summary of types of car brakes and things to know about car brakes so that drivers can refer to them for brake system maintenance and complete their knowledge on vehicle usage. Please always update the latest information from Car From Japan for safe and enjoyable driving.

More than 70 years after its invention by Ralph Teetor, cruise control has become standard on most new-generation cars. In addition to providing a comfortable and safe driving experience, cruise control is generally assumed to save more gas.

It is believed that by maintaining a constant speed, cruise control will save fuel consumption more effectively than if the driver manually keeps their foot on the pedal. So, “Does cruise control save gas?” The answer is “yes or no.” Let’s clarify this question in today’s article!

How does cruise control work?

Cruise control is also known by names such as: speed control or auto cruise. It is a technology that automatically maintains speed, allowing the driver to control the vehicle at a specific speed by managing the throttle connection. At that moment, you don’t need to use the accelerator or lift your foot off the pedal, but you can still be fully assured that your car is running steadily. Most cars have control buttons on or behind the steering wheel.

Cruise control takes speed measurements from different parts of the engine to assess how fast your car is moving at a given time. With the collected data and the specific speed set by the driver, the system will automatically adjust the speed based on input data and the amount of fuel injected into the combustion chamber. After activation, all you need to do is focus on steering. When encountering an obstacle, the driver presses the brake, and the car automatically deactivates cruise control, returning to normal driving mode.

Furthermore, for luxury cars, manufacturers also enhance this system with a speed limiter function. Specifically, when the Cruise Control function is activated, if your car is going downhill, the vehicle will actively slow down. Additionally, drivers can also set a speed limit so the vehicle does not exceed the permitted level when traveling in dense areas. Other modern cars are also equipped with adaptive cruise control. When driving, if your car encounters a slower vehicle ahead, the system automatically slows down and accelerates again when the vehicle in front moves at a faster speed.

If you are driving a long distance, you will get tired of having to keep your foot on the accelerator for several hours continuously. With exceptional capability, the Cruise Control system will make your journey more comfortable.

Does using cruise control save gas?

For a long time, cruise control has been considered a secret to help drivers save fuel. Is it just a myth or could it be a fact? and “Is cruise control better for gas mileage?”

Many drivers assume that using cruise control will reduce fuel consumption, thus saving costs. Now, let’s take a closer look.

In many cases, using cruise control can actually increase a car’s fuel economy by up to 5 to 15%. Vehicles consume the most fuel during acceleration, so the best way to achieve maximum fuel economy is to maintain speed. This is quite difficult to do if you only use the accelerator as usual. However, your car can easily maintain a specific speed through the use of cruise control. In some cases, even the speed difference experienced when going uphill or downhill is quite small when using the cruise control system.

However, please note that cruise control is a speed control (auto cruise) and not a fuel consumption control. The main purpose of the system is to maintain the speed set by the driver, regardless of other factors. Therefore, when encountering a steep uphill road, the car will increase the throttle to compensate for deceleration due to gravity. This means more fuel consumption.

The answer to the question “Is cruise control fuel-efficient?” Cruise control is truly effective when used by the driver under steady-speed driving conditions, on highways, or on flat roads with speed limits. Conversely, if you are driving a car on very busy roads or on mountainous terrain, where you must constantly brake to change the car’s speed, then activating cruise control will not save fuel.

Is cruise control bad for your car?

Our answer is “No.” Many people think that using cruise control will damage the transmission. Contrary to this belief, using cruise control does not lead to rapid transmission wear. In fact, regular use of cruise control can actually reduce transmission wear. This is because the car experiences the least wear when operating at a regular and constant speed for long periods.

Many people mistakenly believe that the car’s transmission will be damaged when the vehicle’s cruise control system causes the engine RPM to rise during downshifting. However, this is not the case at all, as downshifting is a safe method to quickly reduce speed for any type of vehicle.

Notes when using the cruise control system.

Using cruise control contributes to the driver’s comfort and relaxation when the accelerator is “Free.” However, in reality, using Cruise Control also carries many potential risks and can be counterproductive in terms of fuel consumption if driving is not done correctly. Therefore, drivers must be careful when using cruise control to ensure safety and fuel efficiency.

Consider traffic conditions before activating cruise control

During long drives, when using highways, drivers should pay attention to speed limit signs, set the cruise control so the car moves to release the accelerator, creating comfort and reducing fuel consumption. However, if drivers activate cruise control when passing through congested roads or traffic jams, it can be potentially dangerous. Because the driver will not be able to fully control the vehicle or may lack initiative when facing unexpected situations.

Do not use cruise control on certain roads.

When driving the car on steep roads and slippery roads, the driver should not activate the cruise control system. According to experts, the driver’s accelerator is “released,” which can lead to a slower driver response than normal. When operating, cruise control maintains the specific speed, helping the vehicle move steadily. However, when the vehicle is driving on slippery roads or in sharp turns. If the driver does not adjust the speed appropriately, your car can easily skid and deviate from the lane. Therefore, it is best not to activate cruise control in these situations.

Pay attention and stay focused

Cruise control is not an automatic driving system, so the driver must observe and remain focused. After activating the cruise control system, the driver must notice the traffic conditions as well as other vehicles on the road to handle any unforeseen situations.

The driver can adjust the vehicle’s speed using the control buttons usually indicated on the steering wheel. The operation of the accelerator pedal is also released accordingly, but your feet should always be in a position ready to press the pedal. This will help the driver react more quickly and safely. When encountering unexpected problems while minimizing the risk of accidentally pressing the accelerator.

Choose the right speed

The effectiveness of using cruise control depends on the speed. The usual appropriate speed level is around 60 to 80 km/h depending on the type of road. To achieve this speed, technical experts stated that attention must be paid to the RPM. Thus, at 1,500 RPM or less for popular cars, it is the best time to get the best effect.

As usual, the driver wants to drive at a speed of 60km/h. And press the accelerator hard to increase speed from a stop or low speed. To be able to use cruise control to save fuel. The driver should choose to press the accelerator slowly until reaching the appropriate level. The car will accelerate slowly and steadily, even if it takes more time to reach 60 km/h. Please press the accelerator lightly. Maintain this level until you reach the 60 threshold, then press Activate.

Final thoughts

To conclude the topic “Does cruise control save gas?” We want to make it clear once more. You should use cruise control on flat roads or highways. Because it will bring you a more interesting experience and save more fuel. But in other cases like steep roads, traffic jams… you should not activate the utility.

Using cruise control is a great way to control your speed when driving on the road. However, note that you should not use cruise control if you are likely to be tired while driving. Consider the Cruise Control system as a simple utility that helps the driver save energy. This way, you will enjoy your journeys in comfort and safety.

Brake pads are a seemingly simple but complex mechanism. When a car brakes, the brake disc and pads have a direct effect on the car, which can help your car stop at the right time to avoid unnecessary accidents. Among them, if the quality of the brake pads is poor, it will directly affect the performance of the brake. This is the reason why you must choose good brake pads for your car to ensure braking efficiency. Drivers can be confident on every trip when the brakes work smoothly and effectively.

Anyone who owns a car knows that brake pads are one of the most wear-resistant parts. So in addition to replacing them at the right time, you need to know how to choose the pads that best suit your car.

Dangers of Fake and Poor Quality Brake Pads

You wouldn’t risk cheap tires on your car, so why risk using cheap brake pads to repair your brakes? In the market, there are still countless types of poor-quality brake pads and people often buy fake brake pads without paying attention. However, the result of this problem can seriously affect the performance of the braking system.

• Increase braking distance; when braking is urgent, the vehicle cannot be stopped in time, causing an unnecessary accident.
• It is easy to lock the wheels and lose the ability to control the direction.
• There is noise when you brake.
• Faulty pads can affect the rotors. If you have poor-quality brake pads that cause chipping, cracking, and rotor failure, no pressure is applied to the brake which will now be placed directly on the rotor. This causes the rotor to warp, crack, and eventually fail completely.
• Damage tires due to bad brake pads. If the brakes fail due to worn/corroded brake pads, discs, or calipers, it can cause you to press the brakes, leading to unbalanced tires and, ultimately, faster wear than normal.

How to Choose Good Brake Pads?

How to choose good brake pads for the vehicle is an important question that affects your car’s performance and safety. Choosing the right pads is becoming increasingly difficult due to the wide range of brake pad types. Not all brake pads are designed the same way. And each is manufactured with its own materials and processes which also determine the performance, noise, price, warranties, and the ability to make them consistently and safely throughout their “lifespan.” Lifespan is a common prerequisite for many buyers, as it saves you money.

Brake pads should always be replaced before they are completely worn out and according to the manufacturer’s recommendations to maintain optimal braking power. This will reduce damage to other brake components such as brake calipers and brake discs. To choose the high-quality brake pads you need, pay attention to the following aspects:

Driving Condition

The material of the brake pads will depend on your driving style and requirements. Purchasing replacement pads will require you to choose the material they are made of. At this point, you need to determine how severe the braking need is. The best brake pads for your car depend on what you want them to do. The pads contain a sacrificial friction material bonded to a metal backing. Every time you use the brakes, a little of this material wears off. The amount of wear depends on certain factors. For example, harsh braking and frequent sudden stops cause your brake pads to wear out faster. The same goes for driving on dirt roads or other extreme conditions.

Maximum Temperature

Good brake pads must be able to operate in all weather conditions, whether dry, wet, muddy, hot, or cold.

Maximum Temperature: This is the highest temperature the brake pads can withstand before becoming dangerous. During normal street use, brake pads typically will not see a temperature rise above 200°C or 392°F. However, track days are another story, with temperatures reaching up to 1,000°F because the brakes are applied more often and more aggressively.

Friction Response to Temperature

Drivers should note the force applied to the pedal to get the same response during emergency braking compared to normal braking.

Brake Pad Lifespan

Brake pads are subject to wear. Should you consider the lifespan of the brake pads? Pads can last about 40,000 miles on average, but the range is quite wide: Typically, their lifespan ranges from 20,000 to 65,000 miles. Many factors affect the lifespan of your brake pads, from your driving habits to the material of the brake pads. For example, drive slower and you will extend the life of your brake pads.

Brake Pad Material

Many drivers wonder “what type of brake pads is best for my car?” The type of materials you use depends partly on the type of vehicle you drive. Do you want to transport children in a minivan or SUV? Or are you hauling heavy objects in a truck? Brake pads are typically made from one of three materials: organic, ceramic, and semi-metallic, each with its own characteristics and pros and cons.

What Type of Brake Pads Should I Choose?

There are 3 types of brake pads: organic brake pads, ceramic brake pads, and semi-metallic pads. These 3 types of brake pads are considered very durable; they are not only used for daily commuting but are also considered the best brake pads for towing. Made from different materials and specialized processes, each brake pad has different performances and applications.

Ceramic Brake Pads

Manufactured in the first half of the 1990s, a few car manufacturers began using ceramic brake pads. This type of brake pad is appreciated for its smoothness. When used, it makes almost no noise. Compared to organic brake pads, “are ceramic brake pads better?” Ceramic brake pads are much more dominant in terms of dust reduction, reduced wear, reliable operation, wide temperature range as well as driving conditions.

The ceramic material and copper construction allow the braking mechanism to perform well even at high temperatures and to recover faster. The ceramic structure absorbs sound and vibrations in the frequency range that humans hear.

Organic Brake Pads

Upon their invention, brake pads were made of asbestos. However, after a period of use, experts discovered that it is a potentially carcinogenic compound if exposed for a long time. To overcome this dangerous problem, organic brake pads were manufactured. This brake pad uses safer materials such as a mixture of fibers, carbon compounds, rubber, glass, or fiberglass… bonded together by resin. This type of brake pad only creates a moderate amount of friction and does not generate too much heat. Therefore, the car will still run smoothly, without making much noise when braking. Most reputable and high-end manufacturers use organic brake pads when building cars, but this only applies to over 50% of new cars. Meanwhile, other car manufacturers use different types of brake pads in their production lines.

However, organic brake pads tend to wear out faster, so they need to be replaced regularly. Furthermore, this type of brake pad works best only in a low-temperature environment. When the weather is too extreme or braking is too hard, generating high heat, the performance of the brake pads will significantly decrease.

Semi-Metallic Brake Pads

The last type of brake pad friction material is called “semi-metallic” because 30 to 65% of its weight is metal. People use many different metals, from copper and iron to steel, to make this pad. The rest of the friction surface is made of fillers and binders. And a variety of other materials are needed to improve the performance and durability of the brake pads. Semi-metallic pads are extremely popular in the automotive industry and are considered the most versatile brake pads on the market. These brake pads obviously have many limitations, but many people believe that using semi-metallic brake pads remains the best choice. It all depends on its application.

Are Ceramic Brake Pads Better Than Semi-Metallic?

Semi-metallic or ceramic brake pads, which one to choose. It is very difficult to give an exact answer to this question. Before the advent of ceramic pads, semi-metallic brake pads were considered the best brake pads on the market. Of course, utility also fades with new technologies, but semi-metallic car brake pads can still compete with many other high-end products, according to some car manufacturers.

Semi-metallic brake pads may be more performant and economical, although they can be harsh and noisy when used.

Ceramic pads have many advantages, but the production cost of this type of brake pad is higher compared to all other brake pads. Furthermore, the ability of ceramic to absorb heat evenly is not as high as that of other materials. This causes the heat from the braking process to escape from the pads and into the rest of the system, causing wear on associated components. This type of brake pad is also not considered the best choice when driving in very cold weather or on the track. They can also bite less and perform less, meaning that when you first press the brakes, especially in cold weather, you will notice less immediate braking power.

If you regularly use your car for more strenuous work, such as towing on mountain trails, it may be better to opt for ceramic, fully metallic, or higher-quality brake pads.

Points to Consider Before Buying Brake Pads

No vehicle can be considered safe if the brake pads are defective or worn. So, in addition to paying attention to the characteristics of the brake pads, you must also pay attention to some factors when purchasing.

Find a trusted brand: To guarantee the quality and origin of the brake pads, you should choose to buy products from reputable suppliers in the market.

Check the warranty: Many manufacturers (or retailers) offer warranties on brake pads. Although they are designed for gradual wear. If they come with a mileage warranty, it’s a good sign of service.

Do not ignore certifications. Two generic brake pad certifications are included: Differential Effectiveness Analysis (D3EA) and Brake Effectiveness Evaluation Procedures (BEEP).

Final Thoughts

Like tires, brake pads are subject to wear and must be replaced immediately. And bad brake pads can cost you more in the long run. When comparing brake pad brands to use on your vehicle. You must consider more than just the type of brake pad.

You must also consider the key features of each brand, their lifespan, and their quality. The last thing you want to do is buy a low-quality, low-end brand. And have them fail on you and seriously damage your car. Poor-quality brake pads can damage various parts of your vehicle in several ways. For example, faulty brake pads can damage rotors, calipers, and tires if not handled immediately.

It can be quite difficult for drivers to understand all the markings on a tire’s sidewall. But these letters and symbols are very important when you buy a new or different set of tires. If you are a novice, these symbols might look like an algebraic equation or a line of code that needs solving.

Understanding this, we will provide you with some useful knowledge by decoding a popular question: T vs H speed rating, what does it mean? and the difference between the two letters to eliminate your confusion about these symbols.

What Does T or H on Tires Mean?

T and H represent the tire’s speed rating – the parameter indicating the tire’s maximum permissible speed. Knowing this indicator will help drivers choose the right type of tire for the terrain as well as adjust driving speed appropriately to ensure safety in traffic. Therefore, distinguishing these indicators is part of the important knowledge that car owners should equip themselves with.

What Does T on a Tire Mean?

If you were to look at the tire speed rating chart, you would see that the letter T corresponds to 190 km/h (118 mph). This means that the maximum speed you can drive is 118 mph and you should not exceed this speed limit. You typically see this letter on tires for vehicles like minivans or family sedans. These tires are suitable for small vehicles; they are quite robust and can perform on a number of different terrains, but they are better suited for highway driving.

What Does H on Tires Mean?

The H speed rating indicates that your tire can withstand speeds of up to 210 km/h (130 mph) under optimal conditions. The H speed rating is at the lower end or the beginning of the performance tire speed ratings. You can usually see it on coupes and sports sedans. The H speed rating can be a good choice for drivers who always drive at high speeds or need to enhance their car’s performance. This is the maximum speed you can drive at. If you exceed this speed, you risk damaging the tire.

T vs H Speed Rating: What Are the Differences

Based on the definitions above, we can see that the T and H symbols on tires represent the maximum speed they can handle, the recommended tire pressure, a certain load capacity, and ideal road conditions. The H speed rating can handle speeds of 130 mph while T-rated tires can handle speeds of 118 mph. This could be the first difference you easily notice when discussing these tires.

The higher the speed rating, the softer the compound and the more grip the tire offers. Better grip means the tire will stop more quickly, turn more precisely, and have better acceleration.

Thus, the H speed rating will have better handling and braking compared to the T rating. Not only that, but H-rated tires also withstand a higher level of friction and heat resistance than T-rated tires.

The final difference between these two types of speed ratings is their intended use. T-rated tires are suitable for low-speed vehicles (trucks). In contrast, an H-rated tire, due to its better cornering and braking capability, generally makes it suitable for vehicles such as sedans, multi-purpose vehicles, or SUVs.

How to Choose the Right Tire Based on Speed Rating?

Drivers need to know how to choose the right type of tire for the terrain to avoid misuse and unsafe driving. Experts recommend that the vehicle’s speed be 10 to 15% lower than the tire’s speed rating. This is a way to prevent tire wear and potential damage. In case you need to replace a tire, the speed rating must be equal to or greater than the tire installed by the manufacturer. However, the car manufacturer does not recommend users use tires with a lower speed rating, as it can seriously reduce the vehicle’s ability to remain safe.

Furthermore, the tire’s speed rating is directly proportional to the vehicle’s traction and braking force, but this can reduce the tire’s lifespan and performance when operating in low-temperature conditions. This is why tires with high-speed ratings like V, Z, W, and Y are generally suitable for high-performance vehicles in warmer climates.

Additionally, drivers can increase the tire’s speed rating to enhance performance. But car owners must absolutely not lower this rating without reducing the vehicle’s maximum speed to a lower level. The tire’s speed rating indicates the maximum speed at which the tire can maintain its operation under the load pressure specified by the manufacturer. Knowing how to read the speed indicator not only helps drivers choose the right tires but also to control speed more effectively on each terrain to ensure safety on every road.

Cars showing signs of shaking during acceleration are one of the signs that drivers need to clean the oxygen sensor. We can completely clean the oxygen sensor at home with extremely simple steps. Let’s explore in depth how to clean the O2 sensor.

Something You Need to Know About O2 Sensors

An oxygen sensor is also called an emissions sensor. It is one of the most important sensors in a car’s engine system. The main function of the oxygen sensor is to measure the residual oxygen concentration in the car’s exhaust gases. Then, this data is sent to the car’s ECU so the engine can adjust the fuel fill level accordingly, which helps ensure performance while complying with vehicle emissions regulations.

Where Are Oxygen Sensors Located?

An oxygen sensor is usually located in the threaded hole just in front of the engine’s exhaust catalyst. The exhaust catalyst is usually placed near the end of the exhaust manifold, behind the muffler. Vehicles with many cylinders will often have many sensors mounted in the branches of the exhaust system. In some models, the manufacturer installs an oxygen sensor at the rear of the exhaust kit. However, the task of this sensor is solely to assess the exhaust gas processing capability of the exhaust catalyst.

How Does an O2 Sensor Work?

The oxygen sensor is one of the important parts of the engine system. A faulty sensor will prevent the engine from reaching its optimal power. So, how does the oxygen sensor work?

The exhaust is discharged and passes through the oxygen sensor; the contact between the exhaust and the sensor probe will cause the sensor to generate an electric current whose voltage is inversely proportional to the oxygen content in the exhaust gases. If the oxygen content is high or if the air mixture is a “lean mixture,” the voltage generated by the oxygen sensor will be about 0.1 V. If the oxygen content is low or if the air is a “rich mixture,” the voltage generated by the sensor will be about 0.9V. Based on this potential, the ECU will adjust the fuel injectors’ opening time appropriately so that the intake air mixture has an air/fuel ratio close to the ideal ratio.

What Happens When Oxygen Sensors Fail?

When the oxygen sensor breaks, you will see certain symptoms:

Increased Fuel Consumption

When the data transmitted to the ECU is incorrect or no signal is transmitted. At that point, the ECU can only calculate the amount of fuel based on the intake air flow sensor, unable to analyze it accurately because it doesn’t know the amount of oxygen after combustion. This causes that even if there is less oxygen in the exhaust gases, the amount of fuel injected is still high, causing “excess gas,” which makes the car consume more fuel than usual. This fuel consumption can gradually increase if not corrected quickly.

Car Exhaust Smells Like Gasoline

If the car smells like gasoline, it’s likely that your engine’s oxygen sensor is malfunctioning. Because at that time, too much gasoline is pumped into the combustion chamber, the gasoline is not completely burned, so it is discharged through the exhaust pipe, creating an unpleasant smell.

Check Engine Light Is On

The Check Engine light is responsible for notifying when the engine or related parts have an error. Therefore, if you see the Check Engine light on, it’s likely that the oxygen sensor is malfunctioning.

Why Do You Need to Clean the Oxygen Sensor?

To drive with the best performance, the function of the sensor components on the car must be utilized optimally. In particular, the oxygen sensor is an electronic device mounted in the exhaust ducts, in direct contact with the emissions from the engine’s combustion chamber. Therefore, this sensor will perform the task of measuring the quality of the emissions. Then send a signal to the ECU to evaluate and adjust the fuel ratio as well as the amount of air entering the combustion chamber to the most appropriate.

With this role, the oxygen sensor in the car directly affects the vehicle’s performance, avoiding errors such as unstable speed, slow acceleration, and fuel consumption,… Furthermore, it also ensures standard emissions and does not pollute the environment. Therefore, drivers should check the oxygen sensor, recommended 1 to 2 times a year. This will ensure the early detection of problems for cleaning, repairing, or replacing the oxygen sensor, ensuring stable performance.

Note: You must keep in mind that oxygen sensors will not get dirty unless you have serious problems like a bad fuel injector, faulty spark plugs, or cracked ignition coils.

How to Clean the O2 Sensor: 6 Simple Steps

Some car owners wonder: “Can you clean an O2 sensor?“ They don’t know if cleaning an oxygen sensor and then putting it back in place can be an effective method when the O2 sensors have a problem because often, it’s pointless to waste your time trying to clean this sensor when it needs to be replaced. Regarding this question, our answer is “When you notice symptoms of faulty oxygen sensors. We advise against cleaning them; replacing them entirely might be a good solution. Because oxygen sensors are fragile and very sensitive. It can be completely broken if you don’t use an appropriate chemical to clean it.

However, when checking the O2 sensors, if there is no damage requiring replacement, and you want to save some money. Drivers can clean the oxygen sensor to ensure its longevity as well as the functions to run smoothly and efficiently.

Step 1: Prepare the Tools

The tools needed to clean the oxygen sensor include:

• Wrench to remove the oxygen sensor.
• WD-40, gasoline, or carburetor cleaners are the solutions to help remove and clean the oxygen sensor effectively.
• Soft brush to remove “stubborn” dirt.
• Soft towel: dry the sensor after cleaning.
• Additionally, you should also prepare extra gloves and glasses to avoid getting stuck with gasoline and cleaning solutions.

Step 2. Locate the Oxygen Sensor

First, you need to take the car to a spacious place with adequate lighting; you can lift the car to make it easier to locate the oxygen sensor. Then, depending on the model and brand, the number and location of the oxygen sensors may differ. So read the user manual to know the exact position of the sensor. Note that it is necessary to disconnect the power before affecting the sensor, to avoid causing unintended damage. Typically, cars will have at least two oxygen sensors: one located in front of the catalytic converter and the other located behind the catalytic converter.

Step 3. Remove the Oxygen Sensor

After locating the oxygen sensors, spray WD-40 evenly and wait 10 to 15 minutes. This solution has a lubricating effect, making it easier to remove the sensors. Then use a wrench to carefully remove the oxygen sensors from the vehicle to avoid damaging other components.

Step 4. Clean the Oxygen Sensor with Specialized Cleaners

Using gasoline to clean the oxygen sensor is relatively simple. Drivers just need to put all the sensors in a barrel or basin, using plastic or stainless steel, then fill it with gasoline. Then cover the lid and let it soak overnight or for at least 8 hours. The gasoline will clean the plaque and dirt on the oxygen sensor.

Step 5. Clean the Oxygen Sensor with a Soft Brush

After soaking the oxygen sensor in gasoline. If there are still stains, you can use a soft brush to gently scrub to remove long-standing plaque. Drivers should be careful to scrub gently, ensuring the dirt is completely removed. And should not use too much force as it could damage the sensor.

Step 6: Dry and Reinstall the Sensor

Once the cleaning process is complete, use a paper towel or a soft cloth to dry the oxygen sensor. Then, install the sensor in its original position, using a wrench to tighten the bolts, to avoid a loose installation causing problems when the vehicle is running.

Thus, in just 6 simple steps, drivers can clean the oxygen sensor themselves at home, both saving money and helping their car run more smoothly.

Every part of the vehicle has its distinct function and is fully supported by an accompanying tool or amplifier to operate more effectively through the indispensable effects of time and environment. That said, one of the most vital things contributing to the proper functioning of the process and ensuring the optimal long-term health of your vehicle is every type of fluid or oil. If you do not pay attention to these powerful boosters, your car’s performance may drop at any time with fewer signs to prepare in advance. And of course, as part of your goal to surf this information, in the case where you never change the differential fluid, nothing good will happen afterward.

In today’s article, I will go into more detail about differential fluids and the harmful effects behind the habit of leaving this careless lubricant. We will also show you some useful tips on the oil change routine for car components and elements to help you stay with the car much longer than you always think.

What is a Differential Fluid?

Driving towards an unexpected turn is never easy and gives off a feeling of comfort. Have you ever gone through the turns of a street without having to brake, adjust the accelerator, or let the car vibrate successively. It seems like an impossible task, but in reality, it is very likely to be accomplished thanks to your skillful driving ability and the best assistant for typical and surprise turns, the differential (also called the gearbox or transmission).

When the car is moving on a straight road, the wheels have the same speed, so there is no effect on balance and stability. But in turns, the inner wheel has a shorter distance than the outer wheel. So to be able to turn, the speed of the outer wheels must be greater. The differential will then be charged with adding and compensating for the gap between the inner and outer wheels when the vehicle faces every turn or curve in all directions.

More specifically, because it is part of the engine’s powertrain group, it will, as its name suggests, help transmit the balanced power of the vehicle subjected to unusual shocks to each car’s wheel. In short, the differential will control you and your direction will act for a smoother and more stable driving experience.

And as we mentioned quite a bit above, any car part, with the impact of time, will encounter problems related to driving smoothness and gradually face a loss of power. The operation of the differential will depend on a substance called differential fluid. Differential fluid, often called gear oil, lubricates the internal components of the differential, such as the ring and pinion, to prevent differential wear and cause serious mechanical problems when using the vehicle non-stop for a long period.

And do you know why we often refer to this substance as fluids rather than oils? This is due to its greater homogeneity. It has a thicker texture than oil, adheres to the device, and penetrates as deeply as possible.

Typically, there are two types of differential fluids. The first type is mineral-based, a natural type of fluid derived from crude oil. The second is a synthetic differential fluid made in a laboratory. Synthetic differential fluids, like other synthetic oils, can be refined to achieve the best performance for each type and condition of the engine.

Overall, automotive differential fluids will have the following highlighted functions, which reduce friction, save fuel, reduce the wear rate, and maintain viscosity to extend the life of your equipment. It can optimize the power of the gearbox for smooth shifting and smooth operation. Some quality types also protect the differential in particular and the entire vehicle from severe oxidation and rust, keep the temperature in the gearbox lower than usual, and avoid the situation of engine burn-out during continuous operation in hot and high-pressure conditions.

What Will Happen If You Never Change the Differential Fluid

Keeping in mind these promising functions for excellent driving, differential fluid is a vital substance for any vehicle. It will ensure that the gears or differentials operate smoothly and efficiently in a complete system like a car engine.

Over time, the differential fluid will inevitably need to be replaced, and if that does not happen, the gears may wear out faster due to friction and cause a host of problems in the engine. And that is something you never want to happen, at any time, especially when you are enjoying your long-standing freedom and comfort after days of hard work.

Below are some of the effects of not changing the differential fluid when needed. These signs are not too serious at the beginning of the repair process. You can completely ignore and forget them at some point, perhaps just after reading this. However, what your car will undergo in the long term may be irreparable. So beware!

Differential or Transmission Emits a Whining Noise

The most common sign that prompts you to change the differential oil immediately is when you notice a whining noise coming from the rear differential. Not only a whine or groan, but any noise coming from the differential or transmission indicates that the fluid needs to be changed.

If the gear oil becomes lower than the optimal level or becomes too dirty, it can cause the gears to whine or howl as they rotate. These noises will increase with the vehicle’s speed. Never ignore this sign because it can cause a lot of serious damage later, and no one will ever be able to fix it again.

Furthermore, the differential may not make noise even when the fluid is in a low state. When you hear a noise, there is no lubricant left inside or the oil is too dirty. If this happens, you need to check the differential or transmission as soon as possible to avoid the undesirable possibility of a broken or damaged engine.

Jerky Transmission, More Visible in Turns

Although transmission jerking can be caused by some of the deepest and most complex problems, it can also be a potential sign of a low differential fluid level. If you feel the car shaking or vibrating strongly when driving on the road, there is probably something wrong with the differential. When the differential fluid is too dirty or its level is too low, you may notice gear or transmission jerking as well as many annoying noises. If changing the differential fluid does not solve the problems, it is a good idea to carefully inspect the entire vehicle at once to avoid missing hidden issues.

The Burnt Smell from the Transmission or Differential

A burnt smell coming from your differential or transmission is another sign that you need to consider carefully if changing the differential fluid has not yet entered your automatic maintenance dictionary. Furthermore, the smell may come from an oil leak from an old seal, represented by a red spot under your parking space. Burnt smells can also come from overheating of a gearbox due to poor lubrication. The overly old fluid cannot properly lubricate the moving parts, causing the metal components to ignite the oil at high temperatures. Changing the differential oil can partly solve the problem. Otherwise, immediately replace the seal or gasket.

When You Start the Car for the First Time, It is Difficult to Operate.

If the car does not operate normally, it may be because the differential is damaged or the differential fluid is low when you shift a gear and press the accelerator. This will cause a misalignment between the ring gear and the pinion gear. The bearings are overloaded, making it harder to rotate the ring gear. And eventually, the car will not run well from the start.

Very Worn Differential

If you do not change the differential oil for a long time, it can lead to the wear of the vehicle’s differential. And when they are too old, you will no longer be able to drive your car. Even if you do something, there will always be a loud noise heard, annoying like a morning alarm. And up to a certain point, the car can no longer even move.

How Often to Change the Differential Fluid

The frequency of changing the differential fluid will depend on the car brand and the original manufacturer’s opinions. Generally, the user manual provided by the manufacturer will contain the instructions on this. But if you cannot find it anywhere, it is best to contact the manufacturer via their hotline in no time without trying to guess something you need to do next.

The most appropriate time for a gearbox oil change is after the car has traveled about 20,000 to 50,000 miles, depending on the current condition of the car and industry advice. However, the real-time change can be modified because each driver will drive the car differently and take care of it with their specific routine.

If you own a car and expect it to be healthy most of the time, do not wait for it to reach the recommended number of 40,000 miles or 50,000 miles to change the differential fluid, otherwise it may be too late for a problem. These are just theoretical numbers. The driver who cares about the durability and smoothness of the car at every turn will check it regularly and have the fluid inspected or changed, even when the car has only traveled about 20,000 miles. However, in some exceptional cases, such as specific manufacturing off-road vehicles or those usually used for towing, the fluids may be reviewed and maintained at a lower mileage level.

Vehicle owners should observe and regularly check the condition of the oil using a dipstick. Sticks that turn dark brown, or black, or make strange noises are signs that the car’s rear differential oil needs to be changed. This act is strongly encouraged because the longer the gearbox is left unchecked, the more likely each related part will malfunction. And these malfunctions can lead to many engine problems that are difficult to control afterward.

Breaking Down the Differential Fluid Change Cost

Whether we like it or not, it is time to dive into the bitter truth for your wallet for this upcoming project. How much will changing the differential fluid cost you? After all, blind unconsciousness and recklessly continuing to drive the car with its old fluid are never a good thing. Driving on the road with burnt or severely insufficient differential fluid will forever and ever do your car’s engine and your car as a whole, more harm than good. The fluid, ironically, can wear out the differential due to overheating or abrasion of colliding metal parts.

If the fluid is not checked and changed for a long period, the entire differential can fail. So this is a reason that turned what could have been a simple fluid change into a more expensive project. Remember to visit your trusted mechanic after detecting perhaps just one of the above symptoms and change the differential oil in a timely manner.

Renewing this kind of fluid is quite cheap. It varies from vehicle to vehicle and the due mileage also differs. Typically, a healthy differential will require 1 to 4 quarts of fluid. Furthermore, vehicles equipped with all-wheel drive features will have a differential at the front and one at the rear. In this case, the amount of fluid you need to fill the car will be double the standard.

With good expert hands, the process can be done easily in just one hour. The differential fluid change cost will range from about $90 to $150, including a can of fluid charged between $40 and $70, and labor costs from $50 to $80. Depending on the fluid brand and the experience of the mechanic handling your service, the total bill may fluctuate by $10 to $20 more.

Even if both have the same engine structure with the same gearbox, it may suit this type of differential fluid, but not another. So, when you buy a car gear oil yourself, it is best to give the seller detailed information about your vehicles, such as the brand, model, version, and model year, for better advice on choosing the most compatible fluid type.

How to Perform the Differential Fluid Change and Check Yourself

After breaking down the cost of changing the differential fluid, Car From Japan will show you the quick way to check and replace the differential fluid at home without wasting too much money and travel effort. If you wish to perform this check or replacement, you must carefully read the instructions from reliable sources and watch the tutoring videos for a safe and effective process. Otherwise, indeed, you must be very confident in your mechanical and automotive knowledge. So good luck!

Before starting work, you need to prepare a few tools and supplies:
– Differential oil
– A set of jacks with 4 jack stands.
– A basin containing the old fluid drained from the car
– Lots of newspaper or cardboard to line the yard.
– A suction hose and an oil pump (Oil Suction Gun).
– Sockets
– Some old cleaning cloths.

The main task is quite simple, as you will see below. If you are not familiar with the tools and procedures for handling any car part in general, please spend a generous time of about 2 hours to do it carefully and learn from the experience at the same time.

Step 1: First, drive the car for about 20 minutes on the road to warm up the engine, then find a flat parking spot.

Step 2: Raise the car to a height using 4 jack stands to prop the car at that high flat position.

Step 3: Get under the car, slide towards the rear and look up, you will see the horizontal wheel axle, and in the middle is a large box, shaped like a pumpkin. Here is where to get things working: The differential.

Check again if the box cover is still smooth. If there are scratches, they may be caused by collisions with obstacles on the road. Driving on paved roads is usually not a problem. But when the car is driven in so-called off-road conditions, such as rocky areas, trails, forest crossings, and streams, it must encounter tons of convex and concave obstacles protruding from the ground. When driving in such conditions, you must be very careful with the handle so as not to damage the differential.

Step 4: Spread a lot of newspaper or cardboard on the ground under the differential to catch stray oil drops that splash during draining.

Step 5: Find the location of the drain hole and the fill hole on the differential. Place the used fluid container on top of the newspaper, just below the oil drain hole. Put the old fluid pan in place, just below the differential.

Step 6: Starting the fluid draining process, you must first open the fill screw. Because there are many car owners, admittedly novices but in very good spirits, eager to open the drain plug immediately to remove all the old fluid. However, in some cases, the screw has rusted and stuck too tightly on the differential. After all, your car will precariously rest in the middle of nowhere until a qualified mechanic with tools comes to the rescue. Otherwise, you must lower the car, then call someone to take it to the repair shop.

Both cases result in additional costs and a lot of unnecessary effort. Therefore, before draining the oil, you must test the fill screw to see if it can be opened or not. If not, take the car to the shop from the first minute to avoid any subsequent problems

Since its introduction in 1940 until today, automatic transmission has increasingly affirmed its place and importance in the automotive industry. Currently, most cars sold on the market are equipped with automatic transmissions. It is an important part of the powertrain. Today, modern cars are preferred by customers due to many exceptional advantages, in which automatic transmission is considered the “genetic code” that makes this breakthrough.

Having undergone a long development process, AT is increasingly developed with the introduction of more advanced and modern automatic transmissions. You are surely very familiar with the structure of 4, 6, or 7-speed automatic transmissions. But what about the 9-speed transmission? Do you know everything about this model? If not, let’s spend some time with us to explore the topic: “What is a 9-speed automatic transmission?“

9-Speed Automatic Transmission: What’s the Difference?

We can see that each type of transmission has its own characteristics and provides a different driving experience. However, the main goal of development is to increase fuel economy while ensuring the smoothest operation.

As the bridge connecting the engine to the wheel, the transmission acts as a converter of torque and crankshaft rotation according to working conditions. Adding levels and widening the gear ratio range means improving the car’s performance. In other words, it helps the engine operate stably in an optimal state in terms of fuel economy, power, or torque. The 9-speed transmission is considered the limit in the automotive industry because exceeding this threshold increases complexity and weight and cannot compensate for energy efficiency.

“What does 9-speed automatic mean?” The 9-speed transmission consists of a front section with five forward gears plus reverse and a rear section with a low-range gear set and a high-range gear set in a normal upshift sequence. The five gears in the front section are shifted with the rear section in the low range, then the front gears are used with the high-range section, except for the low gear which is only used in the low range, so you have nine progressive forward gears.

It was designed for cars with a transversely mounted engine. The performance increase comes from the wider gear ratios and the lightweight construction of the powertrain. Just like its 7-speed predecessor, the 9-speed automatic transmission adds two overdrive gears and a new clutch design that reduces the overall size of the transmission to fit current vehicles equipped with a six-speed AT.

9 speeds offers extremely short response times and shifts below a perceived threshold. This means that double shifting and direct shifting occur several times without the driver or passenger noticing. The 9-speed transmission has a compact transmission structure: 4 simple gear units and 6 shifting elements producing 9 speeds. The housing case retains the structure of 2 magnesium alloy halves, the case is made of lightweight aluminum.

Supported by a combination of a range of high-tech features, including stop/start technology and the next generation of precision electronic shifting, which provides intuitive sequential shifting. The 9-speed automatic transmission offers the ultimate balance between energy efficiency and performance.

How to Shift a 9-Speed Transmission

How to effectively shift a 9-speed automatic transmission? We are going to solve this problem for you. According to experts, for a 9-speed gearbox to be used optimally, one must drive at high RPM.

Here are the specific shifting procedures as you would perform them with a 9-speed automatic transmission:

Step 1:

You start your engine with the transmission in neutral and bring the vehicle’s air pressure back to normal.

Step 2:

Make sure the range control button is in a low range so that you are sure to be in a low range when you start.

Step 3:

Press the clutch pedal and move the gear lever into the low position. If your car is equipped with an upshift clutch brake, you must press the clutch pedal to the floor before putting the lever into low gear.

Step 4:

The clutch brake will stop the gear from rotating so that the clutch teeth do not clash when they engage with the gear. If your car does not have an upshift clutch brake, simply press the clutch pedal and wait a few seconds to allow the gears to stop rotating on their own now.

Step 5:

Now release the clutch pedal and start moving in low gear, accelerate until you have enough speed to shift into first.

Step 6:

Then double-clutch into first gear and here’s how to double-clutch:

• Begin your shift by pressing the clutch pedal and releasing the accelerator while moving the gear lever to neutral. Once the lever is in neutral, release the clutch.
• Once you have synchronized the gears again, press the clutch and complete the shift.
• Double-clutch all upshifts and downshifts, now continue upshifting through second, third, and fourth gears in the low range.
• When you reach the maximum regulated RPM in fourth gear, check your speedometer and remember the speed. This will help you when downshifting later. Also, while you are still in fourth gear, prepare for the shift into fifth by moving the range control button to the high range.
• When you are ready to shift into fifth gear, simply double-clutch and move the lever into that position which is the same as first in the low range. When the gear lever moves to neutral, the transmission shifts from the low range to the high range. You continue upshifting in the high-range pattern until you reach your desired driving speed.

What about downshifting when the terrain, traffic, or other conditions require a slower speed. Here’s a tip for you:

• As your car slows the engine, the RPM decreases to the point where you can shift into seventh gear. Double-clutching during downshifts requires you to synchronize the gears by revving the engine with the clutch pedal up and the gear lever in neutral.
• After double-clutching down to seventh, then into the remaining gears in the high range, double-clutch shifting while still in fifth gear prepares for the shift into fourth by moving the range control button to the low range which will pre-select the low range.
• Do not attempt to downshift to the low range until your car is at the fourth cruising speed you noted during upshifting. Shifting into the low range at a higher road speed will damage the entire synchronizer assembly.
• When you shift from neutral to the fourth position, the transmission automatically shifts from the high range to the low range, then continues downshifting in the low range.

The Verdict: What is a 9-Speed Automatic Transmission?

During a test, the 9-speed automatic transmission delivered an impressive result by reducing fuel consumption by 6.5%. At the same time, the gearbox helps increase the smooth operation and performance of the engine. We believe that when your car is equipped with this utility, it will provide the driver with interesting experiences.

Hopefully, through the article, you can learn some usage tips that will help you save fuel, reduce downtime, and make driving much easier when using a 9-speed automatic transmission.

When it comes to maintaining your car’s lifespan, getting the oil checked is always a necessity. Ensuring your car’s engine has enough oil is the best way to help it continue running at its best for a long time. To know the condition and the oil level in the engine, drivers always use the dipstick to check the engine’s health. For some reason, the engine oil dipstick is hard to read, how can we see this? Let’s find the answer in the article!

What is the engine oil dipstick?

Checking the engine oil plays an important role in maintaining the operation of the car’s engine system. This solution has the effect of lubricating, reducing friction, and cleaning the internal parts of the engine. You can notice and understand what is happening with the oil inside the engine if you regularly check the engine oil condition. And the dipstick is a useful tool that helps you perform the process simply and quickly.

All internal combustion engines have an engine oil dipstick and this also includes diesel engines. The dipstick is a long, flat metal rod for measuring the level of liquids, especially oil in a car engine.

The position of the dipstick depends on your car’s engine type. Usually, what you see in the engine compartment will be the oil dipstick handle, which looks like a yellow plastic ring, with the text “Engine Oil”.

Step by step to check when the engine oil dipstick is hard to read?

If you are having difficulty reading your car’s dipstick, it might be due to the oil cooling down. When the oil cools, the viscosity is high and the dipstick is hard to read. If the engine oil dipstick is hard to read, you can add at least one liter of oil to the engine. It is important to maintain the engine oil level at the correct level to protect the engine from wear and ensure proper lubrication. To read the oil level on the dipstick correctly, follow the steps below:

Step 1: Park the car on a flat surface and turn off the engine

Try to find a relatively flat surface to park and check the oil. You need to do this to be able to accurately read the information on the dipstick. For example, if the car is on a sloped surface, the oil dipstick may be misread.

You should wait at least 10 minutes after turning off the engine or check the oil when the engine is cold:

• Do not check the engine oil when the car is running.
• Make sure the engine has been idling for a few minutes.
• Wait a few minutes to check the oil to ensure any oil near the top of the engine can drain down.

Step 2: Open the hood and identify the dipstick’s position.

Do not confuse the engine oil dipstick and the transmission dipstick. If you are unsure which dipstick to use, consult the manual provided with your car. Some newer models have an electronic oil display and do not have a traditional dipstick for manual checking.

Step 3: Remove the dipstick and clean it

This is a very important step. Use a cloth to clean the bottom of the dipstick; this will help you get rid of any oil residue that might be splashed onto the dipstick and you can read the oil level accurately.

Step 4: Reinstall the oil dipstick into the engine

Put the oil dipstick back into the engine as it was. Push it all the way down until it is completely back in place. If there is a squeaking sound during reinstallation, remove it, clean it, and try again.

Step 5: Remove the dipstick again

Take out the dipstick and hold it in a horizontal position, find the exact spot on the dipstick. Where should the oil be on the dipstick? Near the end of the oil dipstick, there will be two marks that are standard for “low” and “full,” the lower line is the minimum oil level and the upper line is the maximum oil level. If the oil streak is between the two lines, the oil is at a stable level, good for the engine. If the oil level is near or below the minimum, you need to add more oil.

Make sure the dipstick indicates the correct condition of your engine oil, let’s look at the tips below:

• You should observe and ensure that the oil dipstick is in good condition. If it is damaged or loose, the dipstick may give incorrect results and make reading difficult.
• Make sure the dipstick is clean and free of any debris. This will help reduce friction when reading the dipstick.
• You should notice if the dipstick is pointing in the right direction? If not, you need to change it.

FAQ

What happens if the oil level is too high?

In some cases, the oil level may have increased since the last oil check or there is too much oil on the dipstick. This could be due to condensates (from combustion) or a coolant leak, both of which can be concerning.

The car’s crankshaft is aerated during overfilling of engine oil. Foamy oil does not lubricate your vehicle well and, in many cases, it will completely stop the oil flow, overheat your oil, and cause a drop in oil pressure.

Signs of oil aging

We need to change our oil on time because it is influenced by driving conditions, fuel quality, engine age, and climate. Otherwise, the oil will degrade and not protect your engine. So look carefully at the oil on the dipstick:

• The oil looks quite clear like golden honey: in good condition
• Dark brown to black oil: Need to change the oil

How to know about coolant leak through the dipstick?

If the coolant is leaking, the cooling process will not reach its optimal performance and the engine will overheat. Using the dipstick will help you detect this problem earlier and address it in a timely manner. Brown bubbles or solid brown deposits above the level mark on the dipstick may indicate a coolant leak in your engine.

Another sign is smelly white exhaust smoke. In this case, the oil level on the dipstick may actually increase, indicating that a significant amount of coolant has leaked into the oil reservoir. If you see coolant in your engine oil, your engine must be serviced immediately.

How can I read the dipstick with 4 dots?

Reading a 4-dot dipstick is a bit difficult if you are a beginner. But it’s not as hard as you think. We will show you the detailed way to do it:

• First, you need to adjust the lighting angle and the distance between the dipstick and the reader. Once you’ve done that, you’re ready to start reading!
• Identify 4 marks. The 4 dots on the dipstick correspond to 4 different engine oil levels. To read it, you will need to determine which dot corresponds to which degree of oil level.
• Read between the marks – If there is heavy oil, the line on the dipstick will stay still while the other lines move around it. This means you will need to read between these marks to get the correct result!

Conclusion

Taking a minute can help keep your car in good running condition. Regularly checking your car’s engine oil is an important part of keeping the engine running properly and getting the most miles. Every regular car user, everyone must understand the role and how to use the oil dipstick. This will help maintain the engine’s lifespan, which is likened to the “heart” of the car.

A healthy and durable engine will make each of our trips with our loved ones and family safer and more enjoyable. We hope the article helps you know how to see when the engine oil dipstick is hard to read.

Winter is a season with extreme weather conditions beyond human endurance if we appear without specialized protective shields, especially for children and the elderly. Not only will it be cold when walking in the middle of an intersection, but even in a car, you will also feel the cold with frosty air blocking the view from the window. And that’s why you need a heater that works well before winter arrives. A car heater that doesn’t work will be a threat to your health as well as that of your beloved car in the long term.

That said, I will highlight some of the causes of car heater problems and a few tips to avoid encountering these unwanted issues during your future winter trip to the North.

How does the car heating system work?

The operation of the car heater is easy to understand, even for those not specialized in technical machines. Notably, the car heater will draw heat from the engine. So it takes time for the engine to warm up for a few minutes before you can notice the effect of the heating mode in the car.

To activate the heating mode in the car, the driver must first press the car’s defrost button to dissolve the fog on the windshield and windows in cold or foggy weather. The driver then starts the engine, which speeds up the temperature rise inside the cabin. At this time, car heaters do not generate heat immediately. If the outside temperature is too low, the car has been used for a long time, the engine is large, or the vehicle runs on diesel, the heating mode will take longer to take effect. The driver can set the desired temperature and start the car heater by turning on the fan and adjusting it to the preferred speed.

Many people still mistakenly think that the car’s heater and air conditioner are the same. Another misconception about car heaters is that the car’s air conditioner is a two-way conditioner, which has both cooling and heating effects. Therefore, many people often press the A/C button to start it. However, car air conditioners only have one way to blow cool air. And the car heater warms the cabin using the heat released during engine operation.

Why the car heater doesn’t work: 7 potential problems to consider

The reasons why the car heater doesn’t heat up are unpredictable, as you can never anticipate anything happening in a complex system. Here are the 6 most common causes of the non-heated car condition for quick detection of related issues.

1. Insufficient or leaking coolant

Coolant plays an essential role in the car’s air conditioning systems and engine operation, including heating processes. During our journey, a large amount of heat will be generated due to fuel combustion in the cylinder. That’s why coolant is there, acting as a temperature equalizer for the engine and the vehicle in general.

Some of the heat released by the engine will radiate outward and come into contact with other parts, which, in the long term, can lead to breakdowns and affect the car’s ability to function properly. In many cases, lubricants at a temperature of 200 to 300 degrees ignite spontaneously, increasing the risk of fire and explosion. At these times, the car’s coolant becomes a bridge to transfer heat from the engine to the cooler. Thus limiting the situation where the engine temperature exceeds the permitted limit.

If you encounter a heater in a car that doesn’t work, insufficient coolant may be one of the most common causes. The low coolant level will prevent the vehicle’s heating system from working effectively. As the level drops, air appears in the reservoir, causing localized hot and cold spots that limit performance. If there isn’t enough fluid to reach the heating fault, it won’t be able to blow hot air into the car through the vent. What’s more dangerous is that the coolant can leak, causing a short circuit and wetting the surrounding parts.

Therefore, it is crucial to regularly check the coolant reservoir for the heater to work well. The procedure is very simple because you just need to see the coolant light. If the warning light comes on, the engine temperature is too high.

Experts recommend that drivers add coolant after the first 60,000 kilometers and another 40,000 kilometers for the next refill. Also remember to periodically take your vehicle to a repair shop to have it checked for fluid leaks.

2. Damaged heater core

The second common cause that prevents the car heater from working is the heater core. The heater core has a radiator-like structure, made of aluminum alloy with tubes that carry coolant inside and out and distribute heat to warm the entire car.

If heater core problems occur, the coolant cannot spread widely and the fan will be blocked. Furthermore, the core can easily suffer from rust. Debris and particles entering the cooling system can block your heater core. In general, this problem occurs less often than others, but still exists to annoy you.

Signs of a broken heater core can be easy to recognize if you pay close attention during your daily commute. You may smell a rather strange strong sweet odor in the cabin, and it will become stronger day by day. That’s the smell of leaking radiator fluid. You may also encounter other issues such as blurry car windows for no reason, frequent engine overheating, cool air escaping from the vents, or having to constantly refill the coolant reservoir. If your heater core encounters these signs, the best way is to take it to the auto repair shop to prevent problems from arising.

3. Thermostat problem

The thermostat is another essential component that contributes to the effective operation of the car heater. It helps regulate the car’s temperature, avoids emitting too much heat, and ensures the proper functioning of the cooling and heating system.

With just a little attention, you will be able to precisely identify the problem without having to search to discover it and get headaches from confusion. In most cases, when the thermostat remains closed, it’s because the coolant has been contaminated by a mixture of other types. This causes debris to build up around the thermostat, preventing it from opening. Another cause lies in the fact that the coolant is not cleaned frequently, causing the thermostat valve to rust.

Furthermore, if you see the temperature gauge turn red within the first 15 minutes of driving, your thermostat may be faulty. Not only that, if the engine is hot but the radiator and the upper radiator hose are cold, there must be a problem.

A faulty thermostat will not be able to accumulate heat in the car, which will cause an unwanted car heater problem that doesn’t work. When the thermostat closes, the engine temperature cannot be regulated and the other parts of the cooling system cannot do their job. If the thermostat stays open, the engine will likely never reach the proper temperature and will not operate at full capacity.

Just by solving the main problem, your car heater will have a chance to return to a healthy state faster, avoiding leaving you suffering in the icy cabin in the middle of winter.

4. Air pockets

Simply put, air pockets are air bubbles that enter the interior spaces of the system when you open it or in case of a leak, which seem to replace the fluid lines and prevent circulation.

The gurgling that appears in the dashboard every time you start the engine could be a sign of air bubbles entering the heater core. This phenomenon will cause many difficulties, and one of the most concerning issues is that of air pockets.

The causes of air pockets can be a careless coolant filling process, a faulty radiator cap, or leak holes in the heater control valve. Air pockets in the heater core system will also cause oxidation, making it vulnerable to rust due to the corroded aluminum alloy layer after a long period of use.

With the consequences mentioned above, you can now realize the importance of a heating process that says no to air pockets for the safety of the vehicle’s operation and your driving experience. To completely clean the air pockets in the heater core, you need to seek the help of experts or find the most accurate and comprehensive way to solve the problem yourself.

There is a very useful way to handle the situation in advance. First, remove the coolant reservoir cap and fill the correct amount of coolant after setting the heater to its highest setting. Start the engine with the cap open, then let the car idle for a few minutes. If the coolant level drops while the thermostat is on, top it up. Air bubbles should be purged as a result of this action. Replace the cap once the engine has warmed up and drive to test if the heat output has returned.

5. Faulty HVAC control system

HVAC stands for Heating Ventilation and Air Conditioning. HVAC is an air conditioning system in a car. As its name suggests, the proper functioning of the heater depends a lot on it. The function of the car heater is to generate and distribute heat to the entire area covered by the HVAC system. HVAC systems are used regularly and continuously, over the years and in all weather conditions.

That’s why regular system maintenance is essential. Comprehensive system maintenance brings several benefits, such as savings on repair or replacement costs and the reduction of driving downtime. It can also reduce energy consumption while improving the efficiency of the car’s components.

If you’re still wondering why my car heater doesn’t work every time, you might consider taking your beloved car to a professional repair shop to have the parts checked and replaced before they encounter more serious problems.

6. Faulty heater fan motor

The fan motor is an electric motor that blows hot air through the vent. And it can operate at different speeds to help manage cabin temperatures.

When the fan motor encounters problems, the heating and air conditioning system cannot function properly. This also causes the functions of other components to be interrupted, such as the window defrosting function.

A broken or malfunctioning fan motor will cause many unwanted problems. Like weak wind blowing through the vent, hot air that always blows at a fixed mode, or worse, no heat blowing during the cold winter. The fan motor also catches failing symptoms if it starts slowly or makes grinding noises.

In general, self-checking the condition of the heater fan motor is a simple process. You only need a voltmeter, an electrical tester, repair manuals, or mechanical advice to perform blower motor tests. Don’t leave the heating problem in place for too long. Because it can cause a lot of problems for you and your car. And be careful, bad things don’t only happen in winter.

7. Broken fan motor resistor

As the fan motor speed is continuously changed, the resistor will be subjected to high pressure, which can easily lead to unwanted damage. If there is a problem inside, this part will make the air conditioning system, especially the car heater, ineffective and create functional obstacles.

Some common symptoms of a faulty blower motor resistor emerge from the blower motor. Because these are two parts that are closely related to each other during the operation of the heating system. You may encounter a problem when the blower gets stuck at one wind speed without being able to switch to another. Or you can’t feel the hot air coming out of the upper vent as before.

A faulty motor resistor will disrupt the standard process of the ventilation system. So, to always keep the air clean and fresh in the car, you must always keep the fan motor resistor under control.

Car heater doesn’t work: maintenance tips

Drivers should regularly check the coolant level and add more if necessary. Detecting leaks to ensure stable operation of the heating system and car heater is also an important task.

The heater takes time to warm up the cabin, so the driver should not adjust or increase the temperature too much when starting the car. You can use the air recirculation function to bring the air inside to warm it up again. By doing this, the car can reach the desired temperature faster and avoid unpleasant odors.

For your information, the cost of repairing a car heater is determined by its underlying problems. For other parts such as the fan or thermostat, you can always replace them easily at low cost. Filling the coolant reservoir is also part of a low-cost maintenance process.

However, changing the heater core will be much more expensive. So, in order not to fall into a crisis of exhausting your pocket for car repairs, keep a few useful car heater maintenance tips from experts. Your car will surely appreciate it a lot.

Car heater doesn’t work: recap

By now, you may understand better why your car heater doesn’t work properly for some of the reasons above. In general, car heaters, like most vehicle components operating under the control of a complex system, can cause more serious problems if not maintained regularly.

Hybrid cars (powered by electricity and gasoline) that perform too well are considered “dangerous” by many people. There is an opinion that these hybrids need to be a bit “noisier.” To address this issue, many countries have requirements regarding hybrid car noise. Specifically, both hybrid and plug-in hybrid vehicles must make noise when driving at low speeds (<30 km/h) to ensure pedestrian safety.

Equipped with a sound emission system, we sometimes still hear the strange noise of hybrid cars and wonder if it’s just a normal hybrid sound or if something has happened to your car? To better understand the issue, let’s read the article below.

The reason why hybrid car noise is so strange.

The hybrid brake is damaged.

Like any other conventional car, the working principle of the brake is that when the driver wants to stop or slow down, the driver must apply sufficient braking force to make the wheels turn slowly or stop completely. But in the process, the car’s brake has shown signs of failure. One of the most obvious signs is noise during braking. What causes this phenomenon? The reasons can be:

• Worn brake pads: If the brake pads are used for a long time, the rear metal surface will slowly wear out. This causes the metals to collide with each other and create noise.
• Torn pads: A torn pad will create conditions for parts of the braking system to be exposed to each other, such as rotors.
• Bad brake discs: Worn brake discs are the cause of the annoying noise from the braking system. Brake discs that are no longer flat will produce a strange noise.

Automated gearbox failure

Electric vehicles and hybrid vehicles often use direct or automatic transmissions. When the hybrid gearbox is damaged, you can hear obvious sounds like clunking noises, vibrations, and metal clanking.

Some causes that can be mentioned are improper use of the automatic transmission such as carrying heavy loads, often driving on rough roads, shifting gears when the car is at high speed, or before coming to a complete stop… All these mistakes cause the engine to overheat, making it difficult to shift gears.

Additionally, other reasons can be listed: worn gearbox, damaged wheel bearings, or continuously driving a car under difficult conditions. If the pump shaft or the machine is faulty, you may hear a humming sound.

A hybrid engine has a problem

As you know, unlike diesel and gasoline engines, hybrid engines produce much less noise. The HEV engine is composed of energy and gasoline from the battery. Although it is much quieter, drivers will sometimes hear strange noises: squealing, tapping, clicking, knocking… from the car’s engine and it may worry you. The causes are a dirty air filter, a damaged spark plug or spark plug wire, a clogged fuel filter, or a catalytic converter.

Type of hybrid car sounds

Does any noise emitted by a hybrid car mean your car has a problem? The answer is “No.” There are many types of hybrid car noises, which can easily confuse you about the condition of your car “Is one of the car parts damaged?” Below, we will cover some types of good noises, you don’t have to worry when you hear them:

• When the hybrid engine stops, the cooling system pumps hot coolant into the thermos tank, you can actually hear the pump buzzing for a few seconds while it fills the thermos tank.
• If you are driving at low speed, you hear a strange noise and wonder: what happened to my hybrid car? In this situation, your car is completely normal. Specifically, the Acoustic Vehicle Alerting System (AVAS) of electric and hybrid vehicles must emit a clear and continuous sound when the car is traveling at a speed below 19 km/h so that pedestrians know the car is moving. The volume of this system is allowed to vary from 56 to 75 decibels (similar to an indoor conversation or an electric toothbrush). The noise of the emitted sound will increase when the car accelerates.
• The only noise that electric vehicles tend to make is the noise made by the tires or created by wind resistance, and this only occurs at higher speeds.

FQA

Why does the Toyota Prius make a loud engine noise?

The Toyota Prius is the world’s first mass-produced hybrid (gasoline-electric) vehicle. At the same time, it is also a popular car model due to its fuel economy advantages and environmental friendliness. But there are some complaints about the noise of this car. The problems can range from a simple dirty spark plug to a more serious damaged muffler or catalytic converter.

Do hybrid cars need to be charged?

With a full hybrid or a mild hybrid, the car does not need to be charged because the internal combustion engine will take on both the driving role and provide energy to the hybrid battery. As for plug-in hybrid cars, the battery must be charged by an external power source.

How to maintain a hybrid battery?

Basically, the battery does not require periodic maintenance; the part that needs periodic maintenance is the air filter of the cooling system. This air filter should be cleaned every 10,000 km and replaced every 30,000 km.
