There are many occasions that may require you to work under the vehicle. This could be changing a tire, checking the brakes, or inspecting for a leak or damage. Whatever the reason, it is absolutely essential to use the proper equipment and follow the correct procedure. After all, you will be working under the car, so even a small mistake can cause a serious accident. But how to safely jack up a car?

Jacking up a car may seem simple; it’s a preparation for performing actual tasks. But trying to take shortcuts or using poor quality equipment can cause a life-threatening accident. This process involves using the right equipment and carefully following instructions.

Why do you need to jack up a car?

The reasons can vary. The most common are draining engine oil, removing a wheel, and replacing a flat tire. In fact, you will need to lift the car to access the undercarriage parts.

Some questionable repair shops might scam you during repair work. They might simply top up the oil without draining the dirty oil, use inferior quality products, and overcharge for certain parts. If you know how to perform mechanical work in addition to jacking up a car, you can save a lot of money.

Knowing how to use a car jack can save you in an emergency when you don’t have access to outside help. However, never attempt to change a flat tire on the highway. It’s dangerous for you and other drivers. The best thing to do is call roadside assistance. If this service is not available, you must attract the attention of the highway police by hanging something white (a piece of cloth or paper) on the driver’s side window.

Never attempt to change a flat tire or do anything else by jacking up a car on a hill slope. If going downhill poses a risk of completely destroying the tire, you should park the car near the curb. To prevent the car from rolling downhill, turn the wheels towards the curb and block the wheels on the downhill side.

How to jack up a car: follow the step-by-step instructions

Lifting a vehicle with a jack is a simple operation, but one that requires the utmost caution. Safety must be the priority during this tedious task. This detailed guide will teach you how to jack up a car in the safest and most effective way.

The tools you need

To perform repair or maintenance work on a vehicle, you will need the right tools. Before starting the process, make sure you have these items on hand:

• A jack
• Jack stands (for added safety and stability)
• A few pieces of wood blocks, which can work similarly to jack stands
• Cinder blocks or something similar/wheel chocks
• Lights like wireless LED lights (if the area is not well lit)
• Utility gloves
• Owner’s manual

How to jack up a car: steps to follow

If you want to complete the lifting smoothly, proceed exactly as indicated in the following steps. Do not attempt to improvise unless you are sure it will not cause an accident.

Park the car correctly.

The first thing to do is park the car on a flat asphalt or concrete surface. An uneven surface can cause the jack to shift or tilt, which can lead to serious injuries. If you have a garage, choose a flat spot to perform this operation.

Engage the parking brake and keep the gear selector in “Park.” In the case of a manual transmission, engage first gear. Turn off the ignition and remove the key.

Place the wheel chock.

A chock is a wedge made from sturdy materials. A wheel chock prevents the wheels from rolling unexpectedly. Its bottom is covered with rubber for better traction and a firm grip on the ground.

You must place the chock behind the wheels opposite to the ones you are going to jack up. For example, the right rear wheel should be chocked if you want to lift the left wheel. When lifting the left side of the car, use two chocks against the right front and rear wheels.

Prepare the floor jack.

This part of the procedure for jacking up a car involves preparing the floor jack for the task. The jack’s relief valve must be closed. If it is open, you must close it by turning the jack handle clockwise. Also check for any fluid leaks or damaged parts. You should never use a jack that shows signs of deterioration.

A hydraulic jack is an ideal tool for lifting a vehicle. Some people might be tempted to use the car’s emergency jack instead of spending money on another jack. Don’t do that. The emergency jack is for changing flat tires when there is no other option. A floor jack is stronger, more stable, and can support more weight.

Mark the safe lifting points.

Mark a point where you are going to position the jack. It should be on the part of the car you wish to lift.

Vehicles are likely to have designated areas where you can place the jack. A jack positioned on these points ensures it can support the weight of the entire vehicle without breaking.

There are places where you should never place the jack, such as under the body panel. Placing it in the wrong spot can lead to a life-threatening accident.

Place the jack under the vehicle.

Where to place the jack under the vehicle? This is important because it might not support the weight for long if the placement is incorrect. Place it just behind or in front of the wheel to lift a front or rear wheel respectively. Place it somewhere in the middle between the two wheels when you want to lift the entire front or rear section.

Some vehicles come with dedicated points for placing the jack. There should be one near each wheel, and another additional point may be located between the front and rear wheels. Consult the owner’s manual if you can’t find them. The points are probably marked by a small arrow.

If there aren’t any, calculate the midpoint of the subframe and position the jack under that point. There are certain non-structural components, including the steering rack, radiator, and oil pan, on which you should never place the jack.

The rear differential on some vehicles is strong enough to be used as a lifting point. But you must check the owner’s manual to be sure.

Adjust the jack’s position.

After placing the jack in the correct spot, the next step is to adjust its position because the angle of the car may change after being lifted. Readjusting the position will ensure the jack does not slip.

Lift the vehicle.

After completing all the necessary preparations for jacking up a car, here is the step where you finally lift the car. To do this, push the jack handle down and pull it up quickly.

Continue pushing and pulling the handle until the vehicle reaches the desired height. Once the operation is complete, carefully monitor the vehicle’s stability. It is important that the jack remains exactly on the designated point. If it needs readjusting, lower the vehicle by releasing the jack’s valve, then lift it again after repositioning.

Place the jack stand.

This is the time to place the jack stand (one or more, as needed) under the vehicle. Place the jack stand near the jack so it can firmly support the vehicle. Its location should be under a secure part mentioned above. When lifting both ends of the wheels, you should place jack stands on each side.

Then, you can remove the jack. Simply open its release valve and lower it until the car touches the jack stand. Let it rest on the jack stand while you remove the jack. However, if you don’t need to use the jack for another task, leave it under the vehicle for added safety.

Remove the jack.

The final step is to remove the jack when you have finished the maintenance or repair work. You need to push and pull the jack lever to raise the car a few inches in order to remove the jack stands. After that, slowly open the jack’s release valve to lower the car to the ground. Then, carefully remove the jack.

This is how to jack up a car when you need to perform a repair, maintenance, or inspection. After completing the task and safely removing the jack, you can get back behind the wheel.

Diesel car owners often face significant carbon deposit buildup and occasional engine contamination. The reason your vehicle’s engine behaves this way is blow-by in a diesel engine. Now you must be wondering what blow-by is in a diesel engine, right? Well, it’s not an ordinary issue but a drastic problem that can diminish the vehicle’s engine performance. Several causes are responsible for this behavior of your car’s engine.

So, let’s understand why the diesel engine behaves this way and what blow-by gas means:

What is Blow-by in a Diesel Engine? Causes and Solutions

A serious issue affects engine operation when a cylinder wall and piston have a faulty seal, allowing the air-fuel mixture to leak into the engine crankcase. This is what we call blow-by gases in a diesel engine. Possible causes of this problem can be poor performance, reduced torque and power, or even higher oil consumption. It’s always advisable to follow effective maintenance tips from experts for better understanding. Now let’s see what causes it and how it affects the vehicle.

What Causes Blow-by in a Diesel Engine?

Blow-by is a phenomenon that creates unwanted pressure waves; this process often generates unusual sounds and can damage certain moving parts inside the engine like a cylinder or piston. We often encounter this issue in gasoline engines; nevertheless, diesel engines always have this problem due to the high compression ratio.

Typically, blow-by occurs at the end of compression, at the beginning of combustion, when the spark plug hasn’t ignited yet and the air mixture in the car has spontaneously ignited. For diesel engines, fuel burns in many combustion areas. So, what are the causes of this problem:

1. Worn Pistons

One reason that can answer your question about what blow-by is in a diesel engine and what causes it is worn pistons. Unlike cylinder walls that amplify wear, pistons tend to become smaller. Since aluminum is a soft metal, it easily allows buildup in the combustion chamber and creates grooves in the piston. And this means the air-fuel mixture will accumulate in the crankcase.

2. Damaged Cylinder Walls

Another possible reason leading to blow-by in a diesel engine is damaged cylinder walls. With continuous use, the vehicle and its components wear out. This also includes cylinder walls. Continuous piston and piston ring scraping lead to damage to cylinder walls.

This creates a gap in the cylinder, enlarging it, which makes it easier for compressed gases to pass into the piston. We hope these points help you understand what diesel blow-by is. Worn cylinders can never function as they should. So it’s always recommended to keep an eye on the cylinder.

3. Broken Piston Rings

The third reason could be those broken piston rings. When looking for an answer to the question “what does blow-by mean in a diesel engine,” it’s important to mention this point. Broken or damaged piston rings can cause blow-by in a diesel engine. The incessant friction of the rings in the cylinder eventually damages it. The sealing capabilities of the piston ring can be expected to deteriorate significantly over time. This certainly leads to gases easily seeping behind the ring, which simply results in blow-by in a diesel engine.

Solutions for Blow-by in a Diesel Engine

Excessive smoke, decreased engine performance, or higher oil consumption can be the result of blow-by in a diesel engine. So, how can we fix this phenomenon? The steps below can help:

Check the PCV System:

The PCV, or Positive Crankcase Ventilation, is responsible for regulating crankcase pressure. If you notice a leak or a hose on the PCV system, you need to replace it to solve the problem.

Inspect and Change Piston Rings:

Faulty or worn piston rings are the most common reasons causing blow-by. The consequence is that the rings don’t create a proper seal and gases can’t escape. In this case, we recommend changing the piston rings, but it’s a rather complex task and you should entrust your car to a qualified mechanic to repair it.

Inspect Valve Seals and Cylinder Head:

Inspect the cylinder head for any signs of damage or warping. Damaged cylinder heads can cause blow-by. Additionally, worn valve seals can allow gases to bypass the piston rings. Replace faulty components if necessary.

The Crucial Point

We believe you may now have an answer to the question of what blow-by is in a diesel engine and what causes it. So it’s recommended to keep an eye on the piston, piston rings, and even the cylinder to ensure your vehicle operates properly.

The compression ratio is a determining factor in the behavior of any engine. It is the evaluation of the engine cylinder’s ability to compress fuel and air. Different engines, such as gasoline engines and diesel engines, have different compression ratios. However, the diesel engine’s ratio is comparatively higher. Why are diesel engine compression ratios higher than those of other engines? This question must be haunting you, and you will find the answer right now.

So let’s find out together!

Definition of Compression Ratio

For an engine to function properly under highly variable conditions, the following conditions must be met:

• Air and fuel mixture
• Good compression ratio
• Ignition process

Thus, the compression ratio is calculated by the maximum volume of the cylinder (when the piston is at the bottom of its stroke) divided by its minimum volume (when the piston is at the top of its stroke).

• Gasoline engine: The compression ratio will need to increase to help boost engine power, but the risk of knocking will be high.
• Diesel engine: The compression ratio would need to be reduced to make the engine “quieter,” but in return, lower pressure and temperature conditions would reduce the auto-ignition capability, making combustion more difficult.

Therefore, the automotive engineer will need to limit the compression ratio of the engine using each type of fuel to a certain range.

Why Are Diesel Engine Compression Ratios Higher? – Main Reasons to Check!

Generally, the compression ratio of diesel engines is higher than that of gasoline engines (with the exception of some special gasoline engines like Mazda’s).

A typical gasoline engine has a compression ratio of about 8:1 to 12:1. However, in diesel engines, the compression ratio is typically around 15:1, and there are “special” diesel engines with compression ratios that can reach up to 25:1.

The main difference between gasoline and diesel engines lies in the ignition mechanism. While gasoline engines need spark plugs to carry out the combustion process of the compressed air-gasoline mixture, diesel engines operate on the principle of auto-ignition. When the air-diesel mixture is compressed at high pressure (high compression ratio), the heat generated creates the spontaneous combustion process. This characteristic gives diesel engines high energy efficiency.

To learn more about the reasons, we have listed below the main reasons why a diesel engine has a higher compression ratio than any other engine. So, take a look!

1. According to Application

Diesel engines are ideal for heavy vehicles such as locomotives, ships, trucks, and other gigantic automobiles. Therefore, they have a higher torque application. To start such a large vehicle, a large amount of energy is needed, which ultimately leads to an increased combustion rate. The compression of air is the process that occurs in a large cylinder inside an engine. Therefore, fuel is also burned rapidly. It produces more power inside the engine, which ultimately leads to a higher compression ratio. Therefore, the engine cylinder size and, of course, the application are the reason why diesel engines have a higher compression ratio.

2. Knock Avoidance

Knocking is a serious problem in engines. It occurs when there is abnormal combustion inside the engine cylinder. Knocking problems are generally more frequent in gasoline engines. When the compression ratio increases, the gasoline engine knocks, which is why it is not considered an ideal compression engine by many people. Coming back to the diesel engine, there is no knocking. The larger cylinders provide enough space for your fuel to flow and burn inside the engine.

The main reasons why an engine can produce knocking are:

• Ignition delay inside the injectors
• Increase in temperature inside the engine
• When the fuel injector fails to completely ignite the fuel

Thus, to avoid engine knocking, the diesel engine has a maximum compression ratio.

3. Spark Plug

Gasoline or petrol engines require a spark plug to burn the fuel. The diesel engine does not need a spark plug to generate power, but the high compression ratio is enough to ignite the fuel. For the engine to auto-ignite, a higher compression ratio is needed. Furthermore, diesel is very volatile, and only air compression is enough to ignite the fuel. Thus, to prevent the engine from burning or presenting other hazards, a diesel engine is built to acquire a high compression ratio. Additionally, to handle any unexpected issues with the diesel engine, you can learn some useful maintenance tips from the experts.

Conclusion

So, whenever you wonder why diesel engines have a higher compression ratio, remember this useful information and choose the engine of your choice.

Your car’s coolant plays an essential role in keeping all parts at an optimal temperature and improving engine performance. It can happen that a small coolant leak occurs, which is repairable without spending too much time or money. However, if the leak is not controlled until the cooling system empties, repairs can be quite costly. Vehicle owners should remember that having coolant in the engine oil is never a good idea for the car.

Let’s see what happens when coolant leaks into the engine oil. Coolant is a useful element in your car to keep it cool. However, it can become a source of headaches if it leaks into the engine.

How to handle a coolant leak in the engine oil

If there is a coolant leak in the car, it can overheat and break down. You might then find yourself stranded in the middle of the road. However, if the coolant leaks into the engine oil, the damage will be expensive to repair.

On the other hand, if you try to drive the vehicle without coolant, there is a high chance that it will damage the thermal seal. In addition to leaving your car in the garage for repair, you will have a large repair bill to pay. In the worst case, the car’s engine would fail and require a complete replacement. You can browse online to find the best maintenance tips for the proper functioning of your vehicle.

We will help you understand what would happen if coolant were present in your vehicle’s oil.

1. Changes in lubricant

The mixture of coolant and engine oil can completely alter the properties of the lubricant. The antifreeze would cause the oil to thicken and prevent it from flowing as easily as before. It then moves to other parts of the engine, which require a thinner fluid for lubrication and protection. Due to the coolant leak in the engine oil, an acidic environment is created inside the oil, leading to internal corrosion of the system. Additionally, the additives in the oil are compromised.

2. Oil balls

Once coolant is present in the oil, small oil balls form. These balls measure between 5 and 40 microns but can cause significant damage to your vehicle. They are abrasive and lead to surface erosion. The most common area to check is the inner wall of the car’s cylinder, where these balls cut and notch the wall. They can quickly cause surface fatigue and may even lead to lubrication failure.

In summary

So, when you notice a coolant leak in the engine oil, immediately contact an automotive repair specialist to resolve the issue in time.

Summary of our Engine101 lesson: your vehicle’s internal combustion engine requires a constant supply of fuel, as well as air, as inputs for combustion. This requires that gasoline or diesel be transported from the fuel tank to the fuel injectors or carburetors, depending on the type of vehicle you own, by the fuel pump. It goes without saying that you will need the best fuel pump for a constant fuel supply and optimal engine performance.

You might think that since it’s simply a “pump,” it should be a simple and easy-to-maintain component of your car and that purchasing such a pump should be a no-brainer.

In reality, when it comes to your precious vehicle, especially anything related to the performance of the complex and delicate engine, choosing the best fuel pump that will last you many years on the road and provide reliable service requires some research.

We’ve done the hard work and compiled in this comprehensive fuel pump guide everything every car owner needs to know to get the best fuel pump for their particular vehicle and specific needs.

Learn the importance of a good fuel pump, the different types, symptoms of a bad fuel pump, important purchasing criteria, and a list of the best fuel pump models on the market.

Function of a Fuel Pump

While your engine needs air and fuel to be injected into the combustion chamber, the fuel is stored in the fuel tank.

Therefore, a fuel pump, also called a “fuel transfer pump,” is needed to transfer fuel from the fuel tank to the engine, specifically to the carburetors or fuel injectors, which disperse the fuel into the engine’s combustion chambers.

Fuel pumps accomplish their job by combining mechanical or electrical forces with pressure.

A fuel pump is actually made up of several pumping systems inside a can-shaped container, which is about the size of a small jar of jelly. First, the fuel supply pump works like a vacuum to suck gasoline or diesel from the tank.

The fuel is then filtered through a mesh screen to block any residue in the tank, then introduced into a metering pump. Here, piston-like mechanisms push, pull, spin, and shake the fuel to achieve the required pressure.

Once the fuel has been pressurized to a precise level, it is pushed out of the pump, into the fuel line. From there, a small nozzle sprays a fine mist of fuel into the engine’s combustion chamber. This fuel mist is combined with air at a precise ratio, then ignited to create combustion.

Symptoms of a Faulty Fuel Pump

It goes without saying that when your vehicle’s fuel pump fails, the engine will not receive the correct amount of fuel at the right time, which will harm its performance. Below are the most common symptoms of a faulty pump.

If your car shows any of these signs, you will certainly want to inspect the fuel pump to determine if it needs to be replaced or not, as well as a few other possible culprits.

Difficulty Starting

Since fuel pumps run continuously as soon as the ignition is turned on, they can end up wearing out and deteriorating over time. A weakened fuel pump may continue to pump fuel, but the vehicle may have difficulty starting due to lack of pressure.

A weakened fuel pump can cause the vehicle to require more key turns than normal to start and, in the most severe cases, may even require several key turns before starting.

When a fuel pump fails, fuel cannot reach the engine upon ignition. The engine cranks and turns over but never starts.

Before attempting to replace the pump, it is always wise to check that there is no blown fuse and/or low pressure in the fuel line.

Engine Stalling at High Temperature

Many problems can cause stalling, but when it occurs frequently at high temperatures indicated on the car’s thermometer, the culprit is likely the fuel pump motor. If stalling continues to occur as the temperature gauge rises, it may indicate a deteriorating fuel pump and the need to replace it.

Sputtering Engine

One of the surest indicators of a faulty fuel pump is an engine that sputters at high RPM, as the fuel pump cannot provide a steady flow of fuel to the engine at the ideal pressure. If you are driving at a consistently high speed and the engine suddenly sputters before returning to normal operation, there are most likely problems with the fuel pump.

Engine Overheating

If the pump sends too much gasoline to the engine, it can cause engine surging. Although this symptom is usually associated with fuel pump problems, it can also be a sign of bad gasoline. To understand why this is the case, as well as other symptoms of the common engine surge problem, check out our comprehensive guide on engine surges: how to troubleshoot and repair.

Types of Fuel Pumps

Depending on the type of machine, fuel pumps are powered differently, but they can be classified into 3 main types.

1. Mechanical Fuel Pumps

Mechanical fuel pumps are more common on older vehicles, especially those equipped with carburetors. Before fuel pumps became a necessity for cars, fuel was routed directly from the tanks to the carburetor.

This happened thanks to gravity. Since the mechanical fuel pump pumps fuel into the carburetor, it slows down the efficiency of the fuel supply.

Carburetors are no longer very common as they pump fuel at very low pressure. They are now only used in older models. These pumps are suitable for cases where electrical conductivity can be dangerous.

Over time, mechanical fuel pumps gave way to electric fuel pumps due to improved energy efficiency and the demand for higher fuel pressures.

Mechanical pumps are equipped with a number of valves and levers that help pump the fuel to the desired location. A lever is placed on the camshaft which exerts pressure on the diaphragm. Therefore, they are usually located under the hood, near the front of the engine. The valves serve to prevent the backflow of fuel and thus ensure one-way flow to the engine.

2. Electric Fuel Pumps

Electric fuel pumps do not require a direct physical connection to initiate fuel movement. Instead, these pumps require a steady direct current to transfer fuel. For this reason, they generally improve fuel economy.

Another advantage of electric fuel pumps is that they can be optimized to deliver significantly higher fuel pressures, required by modern fuel injection systems and direct injection systems.

Furthermore, since they do not require a mechanical connection, these units are more portable and easier to use: they can be placed anywhere flexibly. Manufacturers most often place electric fuel pumps inside the fuel tank.

The cost of using cutting-edge technology is higher, but these pumps are well worth the extra dollars as they offer added safety by minimizing the risk of explosion. The pump’s robust coating also serves to avoid damage.

In-Tank Electric Fuel Pump and Inline Fuel Pump

When a fuel pump is mounted outside the tank, it is an externally mounted or inline fuel pump. If it is placed inside the tank, it is an in-tank fuel pump.

In the past, electric pumps were placed inside the fuel tank. This helped reduce the risk of fire from extreme heat or a spark, as both gasoline and diesel are cold in liquid form and do not explode.

On the other hand, if you run out of fuel or take a sharp turn, the fuel flow in the pump can be interrupted, which can not only cause your vehicle’s engine to misfire but also damage the pump itself.

Technology has progressed and the inline fuel pump was developed, which can be safely mounted outside the fuel tank. Balance and stress sensors ensure that if the pump is clogged or damaged, or if the vehicle is involved in a collision, the pump stops, thus cutting off the fuel supply to the engine and killing it.

3. Manual Fuel Pumps

As the name implies, fuel is transferred from the fuel tank to the combustion chamber manually using hand pumps that, by turning, siphon fuel from one place to another.

This type of pump is particularly handy in case of power shortage, as the device does not require electricity and in the case where the car is equipped with a non-conventional fuel tank, such as jerry cans. The manual pump is the cheapest type.

Fuel pumps can also be classified into three types based on fuel flow rate:

1. Low Speed

This category includes pumps that can move 50 liters of fuel per minute from one point to another. These pumps are useful for transferring fuel in smaller vehicles as they minimize the risk of spillage.

2. Medium Speed

By transferring 70 liters per minute, these pumps serve at a moderate speed and are suitable for large trucks or vehicles with large tanks.

3. High Speed

By pumping 90 liters per minute, these pumps do the job quickly and efficiently and are therefore highly recommended for rigorous work. Heavy machinery will get the most out of these powerful pumps.

The Best Fuel Pump: Buying Guide

Choosing the best fuel pump most suited to your vehicle and engine requires thorough research, as there are many purchasing criteria, from flow rate to pressure to compatibility, all of which are important.

Consider the following purchasing factors to decide which is the best fuel pump that offers the right balance between different requirements.

Power

Your engine’s power determines the fuel flow rate needed to run it. As power increases, the volume of fuel needed to run it also increases.

A good indicator of the volume/power ratio is about 10 hp per gallon or 2.64 hp per liter. For example, if your pump flows at 60 gph, it should be able to support a 600 hp engine. However, to actually know the gph, you must also take into account the fuel pressure required for your engine.

Fuel Pressure

Fuel pressure is also an important element in fuel management. Fuel pressure is rated at one gallon per hour and one liter per hour at different psi.

Different engines require different fuel pressures. For example, a carbureted engine typically requires between 4 and 7 psi, while a General Motors small-block V8 LS engine runs at about 58 psi.

It is important to know the maximum pressure required by your engine, as fuel pressure has a significant effect on the flow that a pump can produce. A fuel pump will flow at its highest volume when there is no pressure, or “free flow.” When fuel pressure increases, fuel flow decreases.

Each pump has a different flow rate at a given pressure. That’s why it’s important to examine the flow chart of the pump you decide to buy.

It should also be noted that different types of fuel will produce a different type of fuel pressure. Sometimes, certain fuel pumps can only handle one specific type of fuel.

In this case, they may work with non-designated fuel types but will deteriorate very quickly. Using an incompatible fuel type will create suboptimal fuel pressure, thereby reducing the fuel pump’s durability.

Note:

Fuel pressure determines the use of different types of filters and accessories for better performance. Additionally, electric pump installation locations depend on fuel pressure.

Voltage

Fuel pumps have different flow rates depending on voltage. When voltage increases, the fuel pump speed also increases, which increases the flow rate at a given pressure.

Therefore, when looking for the best fuel pump for your vehicle, it is advisable to check the pump’s rating at a given voltage. Most cars produce about 13.5 volts when running.

Fuel Type

Although most pumps are capable of working with different types of fuels, some are not. So it’s best to check if the fuel pump you are considering works with the type of fuel consumed by your vehicle.

Fuel Pump Locations

Depending on the fuel pump installation location, the pump can vary. Most mechanical pumps are mounted on the engine and placed outside the fuel tank. Electric fuel pumps can be mounted inside the tank or outside.

Materials Used / Durability

Even if you don’t necessarily need a heavy-duty fuel pump for your vehicle, durability is always a crucial factor. A durable fuel pump will save you a lot of time and money on maintenance and offer you better value for money.

Materials that claim to meet the “OE standard” will result in a longer lifespan.

The warranty will be another indicator of a fuel pump’s quality and durability. In general, you can expect that the longer a product’s warranty, the more confident the manufacturer is in its products, or the higher their quality and durability.

Nowadays, a good number of products offer replacement and repair warranties for varying durations.

AC/DC – Alternating Current/Direct Current

DC products are often portable and easier to use.

Purpose

You might be buying a fuel pump for heavy machinery while others are buying it for their daily commute.

If that’s the case, there’s no need to get an unnecessarily powerful fuel pump, even if it’s considered the best fuel pump. That would be overkill and would surely cost you more.

How Long Can a Dealer Keep Your Car for Repair

It’s a frustrating situation: you drop off your car at the dealership for a repair, and days turn into weeks. And you want to know exactly how long a dealership can keep your car for repair?

The answer lies in the complex nature of the repair, the availability of parts, and the dealership’s workload!

How Long Can a Dealership Keep Your Car for Repair?

Generally, dealerships typically have a maximum period of 30 days to diagnose and repair your car under warranty.

However, this timeframe is not always strictly adhered to, and some repairs may take longer.

Several factors can influence how long a dealership can keep your vehicle for repair. Complex repairs requiring specialized parts or tools can extend the repair time.

Furthermore, the dealership’s workload and the availability of technicians can impact the speed of service.

Therefore, it is important to maintain open communication with the dealership throughout the repair process.

Factors Affecting Repair Timelines

Now that you know how long a dealership can hold your car for repair, here are some factors that affect your car’s repair timelines at your dealership!

Repair Complexity

The complexity of the repair has a significant impact on the time required. Simple repairs, like an oil change or tire rotation, can often be completed within a few hours.

However, more complex repairs, involving engine or transmission issues, may require significant disassembly and specialized tools. These repairs can take several days, or even weeks.

Parts Availability

The availability of necessary parts can also influence repair timelines. If the required parts are in stock at the dealership, the repair can be completed quickly. However, if parts are out of stock or need to be ordered from the manufacturer, this can significantly delay the process.

Factors affecting parts availability include the car’s make and model, the specific part needed, and the manufacturer’s production and shipping schedules.

Dealership Workload

The number of vehicles currently being repaired at the dealership can affect the speed of service. If the dealership is experiencing a high volume of repairs, it may take longer to get to your vehicle.

Additionally, the availability of qualified technicians can influence repair timelines. If there are not enough technicians to handle the workload, this can lead to delays.

Manufacturer Repair Guidelines

Manufacturers often provide specific instructions and recommendations for repairs. These guidelines may include recommended repair procedures, specific tools to use, and even estimated repair times.

Although dealerships are generally required to follow these guidelines, deviations can occur due to unforeseen circumstances or the complexity of the repair.

Furthermore, manufacturers may set minimum or maximum repair timeframes, which can influence the dealership’s schedule.

Consumer Rights and Protections

When your car needs repair, you should not only know how long a dealership can hold your car for repair, but also be aware of your rights as a consumer.

These laws vary by state, but generally, they require the manufacturer to replace or buy back a vehicle if it has been repaired multiple times for the same issue.

In addition to Lemon Laws, the implied warranty of merchantability applies to all new and used vehicles.

This warranty ensures that the vehicle is fit for the purpose for which it is intended, meaning, in this case, driving. If your car breaks down or malfunctions repeatedly, this may constitute a breach of this warranty.

Dealerships have an obligation to keep customers informed throughout the repair process. This includes providing updates on the repair status, estimated completion times, and any unforeseen delays.

Negotiating Repair Timelines

Be mindful of Lemon Laws and the implied warranty of merchantability, as these laws can offer protection in certain cases.

By understanding your options, you will be able to negotiate more effectively with the dealership. Express your concerns and expectations clearly and respectfully.

If the dealership is unable to provide a satisfactory timeline, request alternative transportation or compensation such as loaner vehicles, reimbursement for a rental car, or discounts on future services.

It can be helpful to negotiate a deadline for the repair to ensure the dealership takes your concerns seriously. Set a reasonable deadline based on the complexity of the repair and the dealership’s workload.

If the dealership does not meet the deadline, be prepared to discuss consequences. This may include escalating the issue to a higher manager, seeking legal advice, or exploring other repair options.

Alternatives to Dealership Repairs

Although dealerships offer convenient service and a warranty, it can be advantageous to explore other repair options. Independent mechanics often offer competitive prices and personalized service.

When is it not worth repairing a car

Determining whether repairing a car is a significant financial and practical decision is an important choice. This guide will help you assess the costs and benefits to decide if it’s time to say goodbye to your vehicle.

Factors to Consider When It’s Not Worth Repairing a Car

Repair Costs vs. Vehicle Value

The first step in deciding whether to repair or replace your car is to compare the cost of repairs to the overall value of the car. It’s essential to calculate both figures accurately. To determine the cost of repairs, get detailed estimates from several reputable mechanics.

These estimates should outline the necessary parts and labor. Consider additional costs such as taxes and fees.

At the same time, assess the current market value of your car. Online tools like Kelley Blue Book and Edmunds can provide estimated values based on your car’s make, model, year, mileage, condition, and location. Keep in mind that these are estimates, and the actual value of your car may vary.

Once you have both figures, compare them. If the cost exceeds a significant percentage of the car’s value (often around 50%), it may be more financially prudent to consider replacing the vehicle.

However, this is only one factor to consider, and other elements, such as the car’s age, safety, and your personal situation, should also be taken into account.

Age and Mileage

Another element to consider when determining if repairing a car is not worth it is its age and the mileage on the odometer. Newer models often incorporate advanced engineering and materials that can enhance durability and performance.

However, even the newest cars can encounter unexpected problems. While age is a general indicator, other factors should be considered.

Mileage is another determining factor of a car’s condition. High mileage is typically associated with increased wear on components such as the engine, transmission, and brakes.

Driving conditions, however, play a crucial role. A car that primarily travels on highways may experience less wear than one subjected to stop-and-go city traffic. Regular maintenance and careful driving habits can mitigate the impact of high mileage.

Beyond age and mileage, the overall condition of the car is paramount. Factors such as rust, body damage, and interior wear can provide clues about its history and potential future problems.

A well-maintained vehicle with a documented maintenance history is more likely to provide reliable transportation. Conversely, a car with a neglected past may require significant investments to restore its reliability.

Safety Issues

Determining when it’s not worth repairing a car is a complex decision influenced by various factors, including safety.

In case of a safety issue, prioritize your well-being and that of others. Start by identifying essential safety components, such as brakes, steering, and airbags.

Assess the risk of driving with unresolved safety problems. Even seemingly minor issues, like worn brake pads or faulty steering, can escalate into dangerous situations.

Consider the severity of the problem, its potential impact on your ability to control the vehicle, and the likelihood of a sudden breakdown. A car with significant safety issues poses a higher risk of accidents, which could lead to serious or fatal injuries.

Compare the safety features of your car with those of newer models. Technology evolves rapidly, and modern vehicles are equipped with advanced safety systems such as lane departure warnings, automatic emergency braking, and adaptive cruise control.

If your car lacks these features and the cost of repairs is high, it may be wiser to consider a newer, safer car. Remember that investing in safety is an investment in your well-being and peace of mind.

When safety is compromised, you must always carefully assess the risks and prioritize your safety and that of others.

If the cost of repairs outweighs the safety benefits, or if the severity of the problems raises significant concerns, it may be time to consider a safer alternative.

Frequency and Cost of Repairs

The decision to repair or replace a car often boils down to one fundamental question: how much does it cost to keep it running? A steady stream of repair bills can quickly erode your budget, and the cost of repairing your old car may exceed the car’s value.

To determine if it’s time to let go of your vehicle, analyze your repair history. Track each repair by noting the problem, cost, and date. This data can reveal patterns of breakdowns, helping you forecast future expenses.

Assess whether the frequency and cost of repairs are trending upward. Are you constantly facing the same issues or needing major repairs more often? This indicates that your car may be approaching the end of its useful life.

Remember to account for the cost of routine maintenance, such as oil changes and tire rotations, which can also add up over time.

It’s difficult to predict future repair costs, but you can estimate the likelihood of major problems based on your car’s age and mileage. Consider potential repairs such as engine replacement, transmission overhaul, or bodywork.

Keep in mind that these repairs can be extremely costly and exceed the value of your vehicle. If the cost of future repairs seems insurmountable, it may be time to consider a newer car.

Environmental Impact

While an old, reliable car might seem appealing for your wallet, consider the environmental impact of keeping an aging vehicle on the road. Newer cars are often equipped with fuel-efficient engines and cleaner emission systems, reducing their carbon footprint compared to older models.

By opting for a newer, more fuel-efficient vehicle, you can reduce your dependence on fossil fuels and contribute to cleaner air.

Assessing the environmental impact of disposing of an old car involves understanding end-of-life processes.

While some parts can be recycled, others may end up in landfills. The overall impact depends on factors such as the materials used in the car’s construction and the methods used for disassembly and recycling.

However, the responsible disposal of an old car can be a more sustainable option than continuing to drive it and releasing harmful emissions into the environment.

The decision to keep or replace your vehicle should also take environmental factors into account. While older cars may seem reliable and affordable, they often contribute more to air pollution and resource depletion.

Remember that you can always make a more informed decision that aligns with your personal values and contributes to a more sustainable future.

Alternatives to Repairing or Replacing Cars

Car Sharing

You now know when a car repair is not worth it and, unfortunately, giving up car ownership entirely might seem radical. However, carpooling or public transportation could be a game-changer. These options are perfect for your short-term needs.

Car sharing may seem more expensive at first glance, but it can save you money compared to monthly payments and ongoing expenses. Public transportation, if accessible and reliable in your area, can be an affordable and environmentally friendly choice!

Buying Used Vehicles

For those seeking the freedom of owning their own vehicle, buying a used car can be a smart alternative to a new model. Used cars offer a significant price advantage over new cars, allowing you to potentially purchase a higher-quality vehicle within your budget.

Factors such as age, mileage, and maintenance history can tell you a lot about the car’s past and potential future.

As always, buying used cars carries risks, just like wondering when it’s not worth repairing a car, so be mindful of making choices that are suitable and optimal for your finances and needs!

FAQ

• How does parts availability influence the decision to repair a car?

If spare parts for your car become scarce or are only available through specialized suppliers or aftermarket parts, repair costs can skyrocket.

This could be a sign that the car is no longer worth repairing, as finding replacement parts could become increasingly difficult and expensive.

• Can insurance costs influence the decision to repair a car?

As cars age and their value decreases, insurance premiums do not necessarily decrease accordingly. If the cost of insuring your car remains high while its market value is low, this can be another factor indicating that it’s not worth repairing.

• Is there a point where a car’s safety features become obsolete enough to justify replacement?

Modern cars are equipped with advanced safety features such as lane departure warning, automatic emergency braking, and adaptive cruise control.

If your car lacks these features, the additional risk might justify considering a replacement rather than investing in costly repairs.

• Can the emotional stress from frequent breakdowns be a sign that it’s time to stop repairing a car?

Constant repairs and the anxiety of potential breakdowns can harm your mental health.

If the stress of dealing with an unreliable vehicle affects your quality of life, consider moving on, even if the car is technically repairable.

• How do lifestyle changes influence the decision to stop repairing a car?

If your lifestyle has changed, for example, if you need more cargo space, better fuel efficiency, or a more reliable daily vehicle, your old car might no longer meet your needs.

In this case, repairing it might not be worth it compared to purchasing a vehicle better suited to your current situation.

Conclusion

Determining when it’s not worth repairing a car requires careful consideration of various factors.

While the desire to repair your vehicle to extend its lifespan is tempting, the financial implications, safety issues, and overall condition of the car must be weighed against the costs and potential risks!

How to coast in neutral with a manual car

Manual cars are efficient in several ways. You have complete control of the car when driving a manual transmission vehicle. But when you need to coast from one gear to another, following the right method is the best choice. For this reason, we have listed three very useful and accurate methods that will help you find the answer to the question: how to coast from one gear to another in a manual car.

So let’s find out right now.

How to Coast in a Manual Car – The Basic Methods

The manual car is an amalgamation of several parts that require perfect handling. These three useful tricks will help you master the clutch easily. So let’s discover them!

1. With the Clutch Disengaged

When you are driving at high speed and wondering how to coast in a manual car, the best way to proceed is to disengage the clutch while the engine is running. Why is this method effective? Because when you do it with the active engine, the braking system is engaged by it and less fuel is consumed. The reason behind lower (or zero) fuel consumption is that the accelerator does not use fuel because it is not pressed. If you try to reduce speed, the risks of pressing the clutch, shifting to neutral, or even stopping abruptly are higher. Try to maintain speed between 40 and 55, regardless of the situation.

2. In Neutral with the Clutch Disengaged

Some people mistakenly think that if you stay in neutral with the clutch disengaged, you will consume more fuel. In fact, that’s not true! Whether the gears are engaged or the car is in neutral, the engine is disconnected from the wheel. Therefore, no brake will function. Being at this stage is not a sign of increased fuel consumption. However, it is true that a small amount of fuel is consumed, but it is not even counted. Nevertheless, disengaging the clutch in neutral is beneficial for the release bearing.

3. With the Clutch Engaged

When both the clutch and gearbox are engaged, you can coast without any problem. But many drivers avoid doing so because they think the pressure on the clutch can damage the disc. In reality, that’s not even logically possible. When the clutch is engaged, there is no connection between the disc and the pressure plate. However, if you press the clutch for a long time, it would damage the disc. There is a hydraulic or mechanical connection between the clutch fork every time you press the clutch. There is a small part attached to the clutch fork that takes the form of a ball bearing with internal and external rotating areas. These two rotating parts manage the tension equally. Therefore, every part of the car remains safe throughout the clutch facing process.

To Conclude

That’s how to coast in a manual car! Choose one of these methods and enjoy a smooth driving experience with the manual car. So add these useful methods to the list of maintenance tips and get ready to make the most of your manual car.

How to disable the anti-theft system in a car

After parking your car in the basement of a shopping mall, the only thought that comes to mind is: “Is your car still parked in the parking space?” This is why car manufacturers include an anti-theft system inside the vehicle to protect it from theft. These systems work through an electrical circuit that disconnects to stop the current and prevent your car from being stolen by an unauthorized person. However, sometimes this system can be a bit faulty, and the owner may want to know how to disable the car’s anti-theft system.

Car Anti-Theft System: How Does It Work?

Car manufacturers today pay great attention to preventing car theft. An “anti-theft system” is one of the common choices of manufacturers. Equipping an anti-theft device on a car is similar to installing a dashcam, but there will be additional sirens, sensors, and magnetic cards… This system will help you know the location of the parked vehicle via a GPS device or a mobile station. In case of theft, the system will alert and send a message to the car owner’s mobile phone and provide the vehicle’s coordinates.

Read Here How to Disable My Car’s Anti-Theft System

First, you need to understand why your car’s anti-theft system may not be working properly. This can happen due to a dead car battery, which loses its memory key. Even a dead battery in the remote can lead to a passive anti-theft system deactivation, thus leaving your car exposed to theft and other damage. Another reason may include a damaged immobilizer chip in your key or door lock.

In short, if you’re wondering how to disable the car’s anti-theft system, you will need to stop the system for that purpose. We have developed a systematic guide on how you can disable the car alarm system.

1. Checking the Key and Cylinder

The first step in knowing how to disable the anti-theft system of your vehicle is to check the key fob battery. A dead battery would result in the anti-theft system being deactivated. You must ensure that the battery has been properly installed inside the key fob. Additionally, make sure to replace the battery at regular intervals so that the key fob remains activated.

2. Check the Car Door Cylinder

The second step in knowing how to disable the anti-theft system of your car is to check the door cylinder. If your car was damaged in a previous theft attempt, the alarm system may have been deactivated. You should check the lock cylinder or under the door handle, where thieves may have drilled with a screwdriver. If the lock is damaged, try the passenger side one.

However, remember that even if the driver’s door lock is damaged, the passenger door does not necessarily have to be damaged as well.

3. Use the Correct Key

Many cars are equipped with a “valet” type key or a door key, which performs limited functions such as unlocking the doors. These keys are easily identifiable as they have a “V” on the key shaft, or sometimes a different color. It’s possible that the key used does not have the chip required to start your car. This is one of the essential tips for disabling the anti-theft system of your vehicle.

Checking the Car’s Ignition

If the anti-theft alarm is blocking the car’s engine, you will not be able to start the vehicle. You will need to bypass the anti-theft by following the steps mentioned below.

1. Checking the Anti-Theft Light

The first step to disable your car’s anti-theft alarm system is to check the anti-theft light, located on your car’s dashboard and featuring a blue or red light. This is an effective maintenance tip to protect your car from thieves.

2. Check the Anti-Theft Light

If the anti-theft light is no longer flashing, turn the key to the OFF position and leave it like that for a minute or two. This will allow the alarm system to rest; otherwise, you won’t be able to start the car.

3. Turn the Vehicle’s Ignition to the ON Position

We advise you to insert the key into the vehicle’s ignition and turn it to the ON position. This will activate the vehicle’s accessories but not the engine. Then, leave the key in the same position for at least 10 to 15 minutes.

4. Start the Engine

Now, try to restart the car’s engine. If it still doesn’t start, make sure the battery is not dead.

Using the Key in the Car Door

The last method to know for disabling the anti-theft light is to use the car key. You need to use the car key on the driver’s side door and the physical key even if the car is equipped with a keyless entry system.

Finally, turn the key to unlock the car door, but do not release it. We recommend holding the key in the same position for at least 20 to 30 seconds. This will allow the car’s system to know that you have the correct key and bypass the alarm system.

In Summary

So, when you want to know how to disable the anti-theft system of your car, these guidelines will help you accomplish the task without much hassle.

How Long Do Alternators Last

The alternator is an essential component of your car. Using the engine’s power, it recharges your battery and prevents it from discharging and dying. It also provides power to your car’s electrical components, such as the headlights and GPS systems. But how long do alternators last from when the car is new? What factors contribute to the longevity of this important component?

The alternator is an automotive part that requires regular attention because if it fails, you may not be able to start your engine. If your alternator fails, it’s highly likely you’ll need to replace it. Discover how long alternators last, what affects their lifespan, when to replace them, and other maintenance tips.

What Contributes to the Alternator’s Lifespan

An alternator produces alternating current (AC), unlike the generator in older vehicles, which produces direct current (DC), hence its name. Cars equipped with an alternator use a diode pack to convert AC to DC, which the car’s electrical system components need to function.

The main role of the alternator is to prevent the battery from losing its charge and dying because when the battery dies, all the electrical components in your vehicle don’t receive the necessary power to operate.

A few decades ago, the alternator only powered your headlights and a few basic electrical accessories like your radio. In contrast, modern vehicles are now fully equipped with a multitude of accessories.

GPS navigation systems and entertainment systems, for example, consume a lot of power. Additionally, you probably have an onboard navigation system, power windows, power mirrors, and maybe even heated seats. All these elements together consume a lot of power from your alternator.

In short, your alternator works all day, throughout your entire journey. The more electricity you consume with all these accessories, the harder your alternator has to work, and thus, the shorter its lifespan.

How Long Do Alternators Last

Generally speaking, depending on whether you maintain your vehicle appropriately and regularly, you can expect the average lifespan of an alternator to be between 40,000 and 100,000 miles.

Many factors can affect the lifespan of your alternator, so it’s hard to say for sure how long you can expect it to last. However, the alternator typically won’t last as long as your car.

For one, the alternator’s rotor spins on a needle bearing, a component that can break due to wear and tear or dirt buildup. The diodes in the voltage regulator can also fail. Additionally, engine heat puts enormous pressure on the alternator, as it does on other components under your car’s hood.

Can I Drive with a Failed Alternator?

Technically, the car can still run, but only for a short period, as it uses only the energy stored in the battery. You might get a quick start with the help of a friend or a helpful passerby with jumper cables, but the car won’t last very long with a failed alternator.

It is also extremely dangerous to drive this way. This is because a car with low electrical power doesn’t have enough “food” to power many components necessary for its operation. Remember that a number of other important car parts also consume power: headlights, brake lights, interior lighting, engine control unit (ECU), etc.

Even if you’re lucky enough to avoid accidents, you risk getting stuck in the middle of the road due to a failed alternator. If alternator problems manifest on the road, especially during a long trip, your safety is compromised. You should test the alternator and battery at regular intervals, for example, every 4 to 6 months.

Once you encounter one or more of the telltale signs below, you should try to get to an auto repair shop immediately.

Signs Your Alternator Is Wearing Out

Below are the most common symptoms of a failing alternator:

• Warning light on the dashboard: Usually, this light is shaped like a battery, or in some cases, it’s labeled “GEN” (for “generator”) or “ALT” (for “alternator”);
• Dim headlights. This is because the headlights and other parts that use electricity don’t have enough “power” to function normally;
• Interior lighting: the dashboard gradually dims while the car is running;
• Loss of power to various electrical accessories, such as the air conditioner, when your car is idling;
• A radio hum in the speakers. This is a sign that the alternator’s diodes are not in good condition and are leaking energy in the wrong places.
• You hear a screeching noise coming from the front of the car when the engine is running;
• Slow cranking;
• The car doesn’t start at all.

Alternator Maintenance

If you encounter these issues, resolve them immediately. Follow this guide to learn how to test an alternator in less than 10 minutes at home to ensure hassle-free driving. After all, it’s pointless to know how long alternators last without seeking ways to maximize their lifespan. And it’s much easier and cheaper than you think.

There are several ways to test the condition of your car’s alternator. One of them is to use a multimeter, while another common method is to use a digital voltmeter. The multimeter measures a number of different electrical properties, including voltage, current, and resistance, while the voltmeter is used to measure electrical power. Both are available at almost any auto parts or electronics store and typically cost between $10 and $20.

It’s important to always test the battery first when checking the condition of your alternator. To test an alternator, you must first test the battery. This is because the battery allows the car to start; when the car is running, it spins the alternator, and this spinning keeps the battery charged. If the battery is too weak, it won’t start the car, and any subsequent test to check the alternator will therefore be useless.

Among the above symptoms of a failing alternator, if slow cranking only happens early in the morning, the battery is likely the cause. In contrast, if the slow cranking problem occurs while the car is running, meaning when the engine is warm, the alternator is more likely to be the culprit.
