Should you check transmission fluid when it’s hot or cold?

Checking your transmission fluid is essential to prevent serious and costly damage on the road. But is it important that you check it hot or cold?

It’s important to do it right, as incorrect fluid levels can lead to transmission problems. Read on to learn the ideal time and technique for inspecting your transmission fluid.

When to Check Transmission Fluid

Check When Hot or Cold?

As a general rule, you’ll want to check the transmission fluid only when the engine is fully warmed up and idling.

When the vehicle first starts and the engine is cold, the transmission fluid is condensed and hasn’t yet begun to circulate fully through the system. Once warmed to operating temperature and idling, the fluid circulates through all components requiring lubrication and expands to a normal state that the dipstick can accurately measure.

Turning off the engine allows the fluid to drain into the pan, giving you an incomplete picture of the actual operating levels.

Why is there a Hot and Cold mark on the dipstick?

The “cold” mark on the transmission dipstick primarily serves as a factory fill line to ensure there is enough fluid from the start to prevent any damage at initial startup. It does not necessarily indicate a recommended minimum fluid level for continued operation after leaving the production line.

The dipstick’s “hot” mark instead reflects the target operating level for which the transmission was designed. So, while the cold mark provides the factory with a safety net for newly built transmissions, the hot mark is the one to pay attention to when checking your fluid.

Follow the Vehicle Manufacturer’s Guidelines

With so many different combinations of vehicles and transmissions, be sure to follow your vehicle manufacturer’s instructions exactly. Testing procedures may differ slightly between makes and models. Some specify having the vehicle running and idling in park, while others want it in neutral or perhaps after a few minutes of spirited driving.

Consult your owner’s manual for the proper gear selector setting, engine state, required temperature conditions, and any other special conditions to check before pulling that dipstick. Precise steps lead to accurate readings.

Correctly Checking Transmission Fluid Level

Follow these steps for the most accurate results when checking fluid levels in your transmission:

1) Warm Up the Vehicle

Run your vehicle until the engine reaches its operating temperature and the transmission is warm. Cold fluid will provide unreliable readings on the dipstick. Operating temperature ensures the fluid has expanded to the appropriate level for measurement.

It’s a good idea to cycle through all gears (from 1st to reverse) several times. This allows the fluid to flow into all internal valves and passages, thus filling the entire system. Cycling the transmission through all gears ensures everything has first reached its maximum capacity.

Some car manufacturers may even specify that you drive your vehicle as usual for a few minutes, so consult that owner’s manual.

2) Shift to Park

When parked on a level surface with the engine idling, put your automatic transmission in the park position and engage the parking brake. Keep your engine idling at all times during the process.

3) Locate the Dipstick

The location of the transmission dipstick handle can vary by vehicle make and model. Some are found near the engine oil dipstick, but others may be elsewhere under the hood. Consult your owner’s manual or perform an online search to find the transmission dipstick equipped in your vehicle.

4) Remove the Dipstick

Similar to checking your engine oil, fully remove the transmission dipstick and wipe any fluid residue from the end using a clean cloth. This prepares the marked end for an accurate fluid level reading without any leftover fluid or dirt.

5) Reinsert and Remove

Fully reinsert the dipstick into place, then remove it again. This allows you to get a true snapshot of the current operating fluid level, rather than the residual fluid left on the dipstick from your initial removal.

6) Assess Fluid Color and Level

First, check that the transmission fluid itself appears healthy – clear, red, or pink, without dark coloring or strong, strange odors. Then note where the fluid level sits.

Most transmission fluid dipsticks will have a hot (or warm) range, a shaded area, notches, or dots indicating the proper fluid level. That’s where you want to be. Again, check with your owner’s manual to ensure you are correctly interpreting the fluid level marks.

7) Adding Fluid

If your transmission fluid level falls below the correct level, you will need to add transmission fluid to bring it to the appropriate levels.

FAQ

Where can I find the transmission dipstick in my vehicle?

Finding the transmission dipstick in your vehicle is usually a fairly simple process, although the exact location may vary slightly by make and model. Here are some tips to locate it:

• Consult your owner’s manual. The manual will clearly state where to find the transmission dipstick. It might be labeled and placed near the engine oil dipstick, or stowed elsewhere.
• Look near the engine. In most front-wheel-drive vehicles, the transmission dipstick handle will be located towards the front of the engine compartment, near the radiator or battery. Rear-wheel-drive dipsticks are usually found closer to the firewall.
• Identify by shape or label. Most transmission dipsticks have a ring or loop on the top of the handle, whereas the engine oil dipstick is straight. Some have “TRANS” printed directly on the handle. Be sure to remove the correct one.
• Feel the texture. Some transmission dipsticks (but not all) often have grooved metal or plastic handles, as opposed to the smooth engine oil dipstick. This helps differentiate by touch.
• Follow the transmission lines. If you’re still unsure, trace the metal lines going to and from the transmission. This usually leads directly to the dipstick location. The tube will be firmly mounted nearby.

What is the difference between the transmission fluid level when checked hot versus cold?

Checking the fluid level when the engine is hot provides the most accurate measurement of how much fluid is actually reaching all internal components under normal operating conditions.

When the transmission is hot, the fluid expands and circulates more freely, essentially giving you a “full” reading that reflects the amount present once everything has reached temperature. Cold fluid tends to measure lower, being denser and contracted, and will not reveal if there is sufficient volume present to properly fill the transmission once the entire system reaches operating heat and pressure.

Ultimately, you want to mimic the actual operating state rather than just a static cold measurement.

What should I do if my car doesn’t have a transmission dipstick?

Some newer vehicles no longer have a physical dipstick for owners to check the transmission fluid level at home. Often, they use a sensor to measure fluid levels and display a warning message for low fluid. If your car doesn’t have a transmission dipstick, try these instead:

• Consult your owner’s manual. A few models without a dipstick may have another way to check the transmission fluid, such as a plug on the transmission itself. Your manual will tell you if and how this can be done.
• Look for a fill tube. Cars without a dipstick often have a fill tube with markings instead. The car must be running and warmed up to read this tube correctly.
• Rely on an auto technician. If there is no owner-accessible check method, then the fluid requires periodic inspection by a mechanic or service technician. They have the necessary tools to check the levels.
• Inspect based on intervals. With no way to personally check the fluid, rely on drain intervals based on age and mileage instead. Today, most transmissions don’t need changes more often than 60,000 to 100,000 miles.

How to Diagnose a Bad Wheel Bearing Noise: While driving, do you hear growling, howling, or sometimes squealing that increases with the vehicle’s speed? If yes, then know that most of the time, it’s the damaged wheel bearing making noise. “Wheel Bearing – What is it?” – If you have the same question in mind, let’s learn about it first. Then, you can understand and put into practice the ways to diagnose the bad wheel bearing noise.

Introduction to Wheel Bearing

Wheel bearings are steel balls held together by a metal ring called a race. The job of these balls is to reduce friction while the wheel is turning. Used in all vehicles, from bicycles to airplanes, these car components are equipped with a metal axle shaft inside the hub. This hub is located at the center of the wheel, which facilitates bolting the tire onto the wheel. And the bearings are mounted in the hub from the back of the wheel.

What Causes a Bad Wheel Bearing Noise?

In every vehicle, wheel bearings accompany the wheel and also constantly move. While driving, the wheels touch the road, so there can be a wide range of reasons why wheel bearings produce a bad sound. Here are 5 common reasons for bad wheel bearing noises.

1. Driving on Rough Roads

While you are driving your car, the wheel bearing of your car will receive all the pressure from the wheel and tire. Therefore, if you drive over a pothole or a bumpy curb, there will be more pressure on your wheel bearing, which will damage it very easily.

While driving, hitting something is a risk you cannot avoid, leading to increased force on the wheel bearing balls. This will cause small imperfections in the wheel bearings. Driving a car with these faulty bearings for a long time will lead to more heat and wear. Debris will be created due to the wear and will then contaminate the wheel bearing lubricant, causing the wheel bearing to fail more quickly.

2. Poorly Installed

Even if you have replaced your wheel bearings with new ones, you still hear a bad wheel bearing noise. The only conclusion is that the wheel bearings are making bad noises because they were poorly installed (without following the manufacturer’s recommendations).

3. Driving on Flooded Streets

Another reason that causes bad wheel bearing noise is driving on a flooded street. If you drive your vehicle on a street flooded with water, your wheel bearings will be exposed to moisture. The moisture mixes with the lubricant, making the lubricant ineffective, damaging the wheel bearings. In this case, you cannot maintain or repair a modern-style wheel bearing. According to automotive experts, the only solution to water damage is to replace the wheel bearing.

4. Wheel Area Accident

Wheel bearings are connected to the wheel, so if the wheel area is damaged, the wheel bearing will be damaged and then cause bad wheel bearing noise.

5. Bad Shock and Unbalanced Tires

The wheel system can operate stably depending on its wheel bearing, lower joint, lower arm, tire, and shock absorber. If you drive your car with unbalanced tires, some of these other parts will break and cause bad wheel bearing symptoms.

How to Diagnose a Bad Wheel Bearing Noise

Before taking the car to the nearest mechanic shop, let’s learn the three different methods to check the wheel bearing and see if it is faulty.

1. Check the Wheel Bearing by Listening to It

To hear the wheel bearing noise, you need to drive your car at a speed above 30 mph. And, at that time, you will notice that the faster you drive, the noise from the faulty or damaged wheel bearing increases.

Here, it is essential to note that this noise may seem to come from the tires or the window, but in reality, the source of the problem lies in the wheel bearing. The biggest difference one can notice is that the car with good wheel bearings does not produce a howling or squealing noise like the one with bad bearings.

Furthermore, to find out which side of the wheel bearing is damaged, gently turn the vehicle. For example, if the car after turning left produces a bit less noise, it means the problem is with the bearings on the right side, and vice versa.

2. Physically Diagnose the Wheel Bearing by Shaking the Tires

For this step, you need to lift the front of the car by safely supporting it on a jack stand; with the rear tires blocked. This last action is necessary to prevent the vehicle from rolling back. Let’s now start by diagnosing the front wheel bearing and make sure it is the source of the problem.

First, grab the tire at both ends in the three o’clock and nine o’clock positions and shake it back and forth. If, while shaking the wheel, you hear some noise, it indicates a bad wheel bearing. Then, to ensure it is the bad wheel bearing noise and not a malfunction of the wheel itself, repeat the same process by holding the tire in the twelve o’clock and six o’clock positions. During this diagnostic procedure, also check the components behind the steering wheel. As this would ensure that the problem is not from any other part but only from the wheel bearing.

Tip: Before grabbing the tire in the six o’clock and twelve o’clock positions, make sure the vehicle is stable.

3. Use a Scanner to Diagnose the Problem

Before proceeding, it is important to note that not all vehicles are equipped with scanners. Therefore, cars equipped with ABS sensors can actually use this technology. Usually, newer cars have this technology.

For this, you need a device such as an OBD2 scanner (a kind of Bluetooth device), providing all information related to the vehicle’s configuration and the current status of its components. To check the condition of the wheel bearing, connect the device to the tablet/computer. Then enter the specific code for the wheel bearing on the tablet screen and confirm its status.

Therefore, here are the three simple methods that can help check the bad wheel bearing noise. And later, it can help you follow the corresponding maintenance tips.

Wrap Up

Bad wheel bearing noise is a common problem that can significantly impact a vehicle’s safety and performance. It is crucial to promptly identify and address wheel bearing issues to ensure the vehicle’s continued operation and avoid potential accidents or further damage.

Symptoms of Power Steering Failure Every innovation in the automotive science field makes driving safe and easy for us. Power steering is one such innovation that has revolutionized driving. It is a feature in all modern cars that allows us to steer the vehicle without applying much force. Without it, it would take Herculean strength to turn the steering wheel from one direction to the other, as in older cars.

In the event of power steering failure, driving can become a very difficult task. You will still be able to turn the wheels but with immense force. And if the power steering fails suddenly while the car is in motion, the result can be a serious accident since you won’t be able to steer the wheels as they should be.

When we buy a new car, we (humanly) cannot see how prepared we should be in case a car component gives up. With this blog article here, we are preparing you to face an imminent power steering failure by telling you the symptoms.

5 Obvious Symptoms of a Power Steering Failure

Here are 5 of the most obvious symptoms that tell you your car’s power steering is about to fail. Recognizing them in time can help you drive safely and avoid accidents.

1. Squealing and Whining Noises

Any kind of squealing in any part of the car is never a good sign. When you hear a whine or squeal when turning the steering wheel, or when moving the car at a slow pace, it means an imminent power steering failure. It’s probably because the power steering pump is about to fail.

Also, if you hear chuckling sounds under the hood when you start the ignition, your power steering pump is in bad condition. If there is a brake squealing noise, that’s something else. In any case, have it checked immediately.

2. Vibration in the Steering Wheel

This symptom is likely to manifest when the car is idling. And it can often come as a surprise, like an unexpected thunderclap. This vibration can often be turbulent and indicate that the drive belt is loose or damaged. In both cases, replacement becomes necessary. The drive belt needs the correct tension for the power steering pump to continue functioning properly. If not, the pump can fail.

You should, as usual, check the belt tension and cracks once a month.

3. Difficulty Turning the Wheels

This is one of the most obvious symptoms of a power steering failure, but you need to keep something in mind here. It could be due to an insufficient level of power steering fluid, which is most likely the case. It could also be due to insufficient tire pressure or an alignment issue. So, before jumping to a hasty conclusion, have it checked by a qualified mechanic.

4. Insufficient Power Steering Fluid Level

It’s a good thing that you follow the best maintenance tips and regularly check all car fluids. If the power steering fluid level is below the required level, it could mean a leak in the power steering system. A low level can cause noise and pump malfunction over time.

Check for leaks on the ground where your car is parked. Red puddles or a particular smell can indicate that there has been an oil leak and therefore the pump needs to be repaired.

5. Appearance of the Power Steering Fluid

New power steering fluid is red and has a particular smell. Old, oxidized fluid will appear dark gray. If air or water has infiltrated the fluid, it will appear foamy or bubbly. It can also happen that you find chrome particles in the fluid. When you notice this, it’s probably the power steering pump deteriorating.

So, make sure the fluid is red and has a distinctive smell.

What to Do If the Power Steering Fails While Driving ?

Experiencing a power steering failure while driving can be alarming, as it requires more effort to steer the vehicle. However, it is important to stay calm and take appropriate measures to ensure your safety. Here are some steps you can take when encountering this issue:

Hold the steering wheel firmly: With power steering assistance unavailable, you will need to apply more force to steer the vehicle. Use both hands and hold the steering wheel firmly.

Step 1 : Gradually Slow Down

Gradually reduce your speed and avoid sudden braking or acceleration, as the lack of power steering can affect your ability to maneuver quickly. Apply light pressure to the brakes and decelerate gradually to a safe speed.

Step 2: Turn On Your Hazard Lights

Inform other drivers on the road that there is a problem with your vehicle by turning on your hazard lights. This will increase your visibility and prompt others to be cautious.

Step 3 : Safely Pull Over

Look for a safe place to stop, such as the roadside shoulder or a nearby parking lot. Use your turn signals to indicate your intention to stop and proceed with caution.

Step 4: Turn Off the Engine

Once safely stopped, turn off the engine. This will prevent further damage to the power steering system and allow you to assess the situation calmly.

Step 5: Inspect the Power Steering System

After stopping, visually inspect the power steering components, such as the drive belt, fluid level, and hoses, if you have the necessary knowledge and experience. If you notice obvious problems, like a broken belt or a fluid leak, it can help you understand the cause of the failure. However, keep in mind that it may not be advisable to attempt to fix the issue yourself unless you possess the required expertise.

After performing all these steps, you should seek professional advice to diagnose and repair the power steering system in a timely manner.

You must recognize the symptoms of a power steering failure before it’s too late. Remember; a stitch in time saves nine. So, beware of these 5 symptoms.

How Many Amps to Start a Car? Have you ever been curious about this? You might need to jump-start the car or buy a new battery, and knowing the amp requirements is necessary for these things.

Important Factors to Consider

There is no clear answer to the amp requirement for starting a vehicle. Several factors come into play, including the operating voltage and the condition of the starter and wires. But the key factors are the engine’s displacement, the type of oil used, and the ambient temperature. A small engine may only need 50 amps for the initial boost, but a larger engine will require more amps. Similarly, other factors also determine the number of amps.

Oil

The fuel used in the car or its viscosity, to be more precise, plays a role in determining the amps. For example, an engine using 5W-15 oil will start more easily than one using 40W oil.

Temperature

Ambient temperature actually affects the engine oil, not directly the battery’s amperage. Oil becomes thicker at colder temperatures, resisting free flow. For this reason, the battery consumes a greater amount of current at lower temperatures.

How Many Amps to Start a Car?

Most small and medium-sized cars will not need more than 400 amps. This is probably sufficient for most compact SUVs and light trucks. Larger vehicles will require more amps, probably 1,000 amps. Remember that the amps needed to start the engine are always lower than the battery’s cold cranking amps (CCA).

Another thing to consider is that a high-amp jump starter can start a car that requires fewer amps. For example, a 1,000-amp jump starter will work for a vehicle that needs 500 amps to start. But it will not be sufficient if the vehicle requires 1,300 amps.

If you buy a 400-amp device, it will not boost a car that needs 800 amps to start. But the car may not respond due to a dead battery. For example, you might have left your car radio or a light on all night, which drains the battery. In this case, a 400-amp unit can charge the battery, which can easily restart the engine.

Simply connect the power pack to your battery and wait a few minutes to let it recharge. Buying a high-amp power pack is the right decision, but a cheaper 400-amp pack is not bad either. You can use it more than 30 times to boost your vehicle effortlessly.

The Voltage Calculation

So, now you know how many amps it takes to start a car, but the estimation is a bit different for voltage. If you have a 6V battery, do not plug it into a 12V source, or it will explode.

The starter’s power is calculated in watts, which you get by multiplying volts by amps. For a 12V battery, the engine will need about 200 amps to start. But the figure will increase when the battery voltage drops.

So, the things to remember are that you can use a more powerful amp pack but not a more powerful volt pack.

Whether it’s about bringing your engine back to life to restore it to like-new condition, customizing it for maximum performance, or as a hobby for a classic car, there are many cases where an engine rebuild is better than just repairing parts. Rebuilding an engine can be a challenging and intimidating task, but it’s still possible in your own garage with this comprehensive guide on how to rebuild an engine.

In this guide, you’ll not only find detailed step-by-step procedures and practical professional tips but also an informative and important discussion on the different options for any car owner needing an engine upgrade or overhaul. These include when to rebuild an engine and when to repair it, as well as a comparison between rebuilding the engine and replacing the existing engine with a “remanufactured engine.”

Partial Repair vs. Complete Engine Rebuild

There are two approaches to improving an engine that is deteriorating after many miles. You can either replace individual parts as needed to save money, known as the “piecemeal” approach, or perform a complete engine rebuild.

The piecemeal approach involves replacing only the worn or broken parts and leaving everything else intact. This maintenance approach typically tries to make do with standard-sized spare parts such as bearings, rings, pistons, and valves.

Obviously, the only underlying motivation here is economic, and you can expect such standalone repairs to keep your vehicle running without significantly improving engine performance.

So, when does the piecemeal approach make sense? When the vehicle and/or engine aren’t worth spending a lot of money on due to old age or low resale value, only the parts that absolutely must be replaced for the engine to keep running are changed. Other repairs can wait for the next owner.

The second approach to engine upgrade is to perform a complete overhaul when the engine needs major repairs and/or you’re hoping for significantly improved performance. This is certainly the more expensive approach, but it also yields much more durable and enhanced results.

By replacing major wear components such as rings, pistons, bearings, exhaust valves, the timing chain or belt, the engine is restored to “like-new” condition. This approach may involve purchasing an engine kit or buying the necessary components individually based on the owner’s preferences.

This usually also requires performing machining work, such as turning the crankshaft and resurfacing the cylinder heads.

Rebuilding the Engine vs. Replacement with a Remanufactured Engine

If you opt for a complete engine overhaul, you have two options: rebuild it or replace it with a “remanufactured engine.” There are pros and cons to each choice.

First, not all engines are rebuildable. If the engine block is cracked or severely damaged, rebuilding it is probably not possible.

Second, the internal parts needed for your engine may not be available, although the aftermarket usually has a sufficient supply of components for the most popular engines. It’s always wise to check availability first before starting the actual work.

The third consideration is your level of DIY automotive skill and the time you have. Rebuilding your engine yourself makes more sense if you’re sure the engine block can be reused, if the necessary parts are available and affordable, and if you have the time and ability. The rebuilding process typically requires machining work and you should expect to spend up to a week, probably more, on this project.

If the above conditions aren’t met, consider replacing your old engine with a remanufactured engine. Most remanufactured engines are made by reputable companies and come with a warranty.

Shop around to estimate whether this option will be more affordable than rebuilding an engine yourself, the availability of a remanufactured engine compatible with your vehicle, and the logistics needed to unload a 600 lb engine from a freight truck.

How to Rebuild an Engine: What You’ll Need

If you’re considering disassembling your existing engine down to the bare block and rebuilding it, you’ll need a few things.

Engine Hoists

You’ll need to start by removing the existing engine from your vehicle. Most DIYers use an engine hoist, also called an engine crane. To remove an engine in your own garage, basic engine hoists with a lifting capacity of 1 or 2 tons will be more than adequate for this task.

Load Leveler Bars

When your engine is supported by chains on both sides, it can tilt to one side if the weight is unevenly distributed, which is a challenge when removing an engine. To correct this, an engine load leveler bar allows you to move the horizontal support bar left or right as needed to balance and straighten an unbalanced load. Some load leveler bars are included with hoists.

An Engine Stand

Once you’ve removed the engine from the vehicle, you’ll need to take it off the hoist. An engine stand allows you to securely and safely mount the engine block. Most stands offer the ability to rotate an engine block into any position so you can easily work on all sides.

Other Tools

• Engine rebuild kit
• Camshaft bearing tool
• Cylinder bore honing tool
• Cylinder bore ridge reamer
• Piston ring compressor
• Rod bolt protectors
• Silicone gasket maker
• Timing gear puller
• Torque wrench
• Wheel chocks
• Engine assembly lubricant
• Water-displacing lubricant
• Basic hand tool set
• Electric drill
• Brass punch
• Air compressor
• Air blow gun and hose
• Fender covers
• Jack stands
• Flashlight
• Masking tape
• Permanent marker
• Oil drain pan (at least 2)
• Plastic sandwich bags and boxes: for storing and organizing hardware and parts
• Service manual

New Components for an Engine Rebuild

When an engine has accumulated a lot of miles, the internal parts may be worn or damaged and need replacement. The engine parts you’ll replace when rebuilding your engine will depend on their condition.

In the engine block, typical wear items include pistons, piston pins, piston pin bushings, piston rings, connecting rod bearings, and main bearings. Crankshafts are machined if possible and replaced if they can’t be machined. Connecting rods can be reused or replaced.

You may need head gaskets, valve covers, valve cover gaskets, oil pans, oil pumps, harmonic balancers, and timing covers. If you’re rebuilding your existing cylinder head, you’ll need new intake and exhaust valves, valve springs, rocker arms, pushrods, and their associated hardware. Sometimes, you might be able to purchase complete cylinder heads with associated camshafts and valves. You’ll also need new head bolts to secure the heads to the block.

Some other necessary parts include water pumps, associated pans and gaskets, throttle body assemblies, and flywheels.

How to Rebuild an Engine: The Steps

Below are the steps to follow for a complete car engine rebuild.

1. Remove the Engine

Step 1: Position the vehicle near your hoist

You’ll need a large, well-lit garage with a flat surface, with enough space to position your hoist and maneuver.

Step 2: Remove the engine hood

Mark the hinge bolts so you can find them later. While carefully loosening them, ask someone to help you as you slide it. Note that some hoods have electrical connections for the headlights, turn signals, and fog lights mounted on them. Disconnect these as well. Step 3: Disconnect the external engine components

For safety reasons, it’s important to note that you should disconnect the battery ground cable before doing anything else.

1. Next, drain the coolant and radiator hoses. Be very careful not to damage the metal clamps, which are harder to replace than the rubber hoses.
2. Remove the radiator and fan shroud.
3. Loosen the alternator, tensioner assembly, cooling fans, and belts.
4. Disconnect the intake air supply and fuel lines. If your car has a pressurized fuel system even when the engine isn’t running, drain the fuel and release the pressure before disconnecting them.

Tips: It’s recommended to take close-up photos and label parts with markers for reference as you go, considering the many parts of an engine. This will greatly facilitate the reassembly process later.

Step 4: Remove all electrical connections from the engine

To disconnect the transmission, you must first disconnect the exhaust manifold and unbolt all visible electrical connections to the transmission. You can leave the spark plug wires for later.

Step 5: Remove the bolts that secure the transmission bellhousing to the engine

Lift the car and place it on jack stands, then support the transmission from underneath with additional jack stands. It’s very important to use a support under the transmission before disconnecting the bolts, because once you loosen them, there will be nothing supporting the transmission.

Note: In most cases, the transmission itself doesn’t need to be removed from the vehicle, as long as it can be safely supported when the engine is lowered.

Step 6: Use the hoist to remove the engine

Connect the hoist to the lifting points on the cylinder heads or the largest bolts near the top of the engine and slowly adjust the leveler to begin lifting the front.

2. Disassemble the Engine Block

Step 1: Get the manual for your specific vehicle

It’s essential that you refer to the engine manufacturer’s instructions to understand all the necessary specifications and peculiarities for rebuilding your specific engine.

Tips: Check the identification and casting numbers of your engine to make sure the engine you think you’re working on is indeed the engine you’re working on.

Step 2: Inspect the engine

Look for any signs of overheating, cracking, and burning on the block. Check for any fluid leaking from the many plugs and seals between components. Also check for any excess gasket sealant left from previous maintenance.

Step 3: Inspect external components

Inspect the alternator belt for any signs of wear by spinning the pulley and listening for any unusual noise. Then, inspect the distributor for any signs of play by applying some pressure to it. Also inspect the clutch assembly for wear.

Step 4: Remove the exhaust manifold

If the exhaust manifold bolts or studs are corroded, be careful to loosen them without damaging them. Using lubricants can help. Otherwise, extremely stubborn bolts may require heat to loosen.

Step 5: Disassemble the rest of the engine

Start with the oil pan and valve covers, then the cylinder heads. Protect the lifters when lifting the cylinder heads: if they are bent or damaged, they will need to be replaced.

Step 6: Check the cylinder bores

If the cylinders are too worn, the chances of a successful rebuild will be slim. You may want to use a micrometer to determine the bore diameter, or you can get a good idea of cylinder wall wear by looking at the cylinder ridge. The ridge is the point where the cylinder isn’t worn because the rings don’t go that high in the bore. Cylinder wear must be below this point.

Generally, if the wear is less than 2/1000 of an inch, the original pistons can be reused; otherwise, the engine will need to be bored and oversized pistons used.

Next, remove the cylinder ridge near the top of the bore with a cylinder ridge reamer. This will allow the pistons to be removed without damage and allow the pistons to be reinstalled with new rings.

Step 7: Removal of piston and rod assemblies

After removing the rod caps from the rods, place rod bolt protectors on the rod ends and protect the bolts to prevent them from scratching the engine block. Once removed, put the same rod cap back on the corresponding rod and keep them as numbered, matched, or paired sets. Keep the parts marked or in order to put them back later into the correct cylinder from which they were removed.

Step 8: Remove and inspect the crankshaft

Remove the crankshaft using the crank mounting plates. Keep the old main bearings in order, inspect them for any wear and excess dirt. Remove the camshaft, balance shafts, and auxiliary drives. Keep everything organized as you’ll need to put them back in the correct order. Remove the cam bearings, paying attention to their position.

Check for cracks and any signs of overheating. Measure different dimensions of the crankshaft: journal diameter, out-of-round, taper, and runout. Compare this to the dimensions specified in the workshop manual.

If some dimensions don’t match, mark them and send the crankshaft to a machine shop to have it resurfaced. Then, measure the crankshaft again so you can replace the bearings to get a clearance between the crank and bearings that meets specifications.

Step 9: Finish disassembly

Remove the core plugs, brackets, guide pins, and everything else still attached to the outside of the engine block. Check the engine block for any cracks.

Meaning of “Check AWD System

All-wheel drive (AWD) systems send power to all four wheels. All-wheel drive is found on many modern vehicles, especially in regions that tend to experience poor winter weather conditions. If there is a problem with the AWD system, you will often see a message indicating “Check AWD System” or something similar.

Not sure where to start? Keep reading to understand what this warning means, what can cause it to appear, and what you should do if this message appears.

Meaning of “Check AWD System”

If you see the “Check AWD System” message appear on the instrument cluster, it indicates there is a problem with your vehicle’s all-wheel drive system, whether it’s a Toyota Highlander, RAV4, Lexus RX350, or another model.

While this is most common on Toyota and Lexus models, other car manufacturers use similar messages to report issues related to the all-wheel drive system. You might see a message saying “R.DIFF TEMP”, a check engine light, “Check AWD System”, or simply “AWD”.

Causes of AWD System Problems

1) Overheated Differential

An overheated differential is a fairly common trigger for all-wheel drive system warnings. Differentials can overheat when you drive the car with mismatched tires or when you drive hard for extended periods. You are more likely to overheat the differential in hot weather and under extreme driving conditions.

2) Low or Old Transmission or Differential Fluid

If your differential fluid is old, too low, or the wrong type, the parts inside the differential or transaxle will not be lubricated properly. This can lead to increased wear, slipping, grinding, clunking, and other unusual sensations while you are driving.

If you have recently replaced your transmission or differential fluid and you start noticing these issues, check that you replaced the fluid with the correct specifications. Your owner’s manual should contain a list of specifications you need to follow for each type of fluid.

3) Mismatched Tires

All-wheel drive systems tend to be more sensitive to differences in tire diameter. This is because many all-wheel drive systems are implemented using one or more limited-slip differentials. Since these limited-slip differentials aim to limit wheel slip, they produce heat. Excessive heat can wear out the differential prematurely.

Limited-slip differentials have to work harder when the wheels are spinning at different speeds for long periods, as they would be when the tire diameters do not all match. If you find that one or more tires do not match, you can sometimes find a tire shop that will shave a tire so that the tread depth matches all four tires.

Never forget to rotate your tires so you don’t end up in this situation. Rotating your tires is fairly inexpensive, but replacing part of an all-wheel drive system will cost you a lot if this maintenance task is neglected.

4) Transmission Problems

Transmissions are essential components of the drivetrain that transfer power to each of the differentials in an AWD system. Many front and center differentials are integrated into the transmission case. This is what the manufacturer often calls a transaxle.

Transmission problems can cause a number of issues for the AWD system, including shifting problems, transmission slipping, and grinding. Unfortunately, many transmission problems require expensive repairs.

5) Problems with Traction Control or Stability Control Systems

Not all AWD systems work the same way. Some vehicles rely heavily on their traction or stability control systems to limit wheel slip. If you are experiencing problems with your anti-lock braking or stability control systems, you will likely also see an AWD warning on the dashboard.

Traction control and stability control systems are mostly electronic, but they make extensive use of wheel speed sensors (also called ABS sensors). Make sure your wheel speed sensors are working correctly. You can check your wheel speeds using a high-quality scan tool.

6) Disconnected Sensors, Wiring Problem, Bad Ground

Sometimes the cause of an AWD system problem can be as simple as a disconnected sensor or a wiring issue. Modern AWD systems use sophisticated electronic components and software to monitor and control the AWD system. Some AWD systems use the brakes to control wheel slip, which is cheaper and easier to implement than a limited-slip differential.

A disconnected sensor, a wire with worn insulation, or a bad ground can trigger an AWD system warning if the ECU detects an erroneous input. Although wiring problems can be a huge headache, finding a disconnected sensor is fairly straightforward if you have a factory service manual.

If you were just working there, it is often quite easy to retrace your steps to make sure you didn’t forget to reconnect anything once your maintenance tasks were completed.

7) Problems with an Electric Motor or Hybrid Battery

Some hybrid vehicles use a gasoline engine for one axle and an electric motor for the other. Electric vehicles can use two motors: one motor for each axle of the vehicle. If there is a problem with an electric motor or the hybrid battery, one or more axles may not receive power.

If you are experiencing a problem with the hybrid battery or an electric motor, you should see an additional warning on the dashboard indicating this issue. Hybrid batteries can deteriorate over time, but they are replaceable. Unfortunately, the cost of replacing a hybrid battery can be extremely high.

Frequently Asked Questions

What should I do if the AWD system warning light comes on?

If the AWD system light comes on, it is important to have your vehicle inspected as soon as possible. As mentioned above, the light can indicate various problems, some more serious than others.

If you have access to an OBD2 scanner, use it to see what error codes are stored in the ECM that could be causing the AWD light to come on and go from there. Otherwise, schedule an appointment with your local dealer or a good independent mechanic who specializes in your vehicle brand.

Can I still drive my vehicle if the “Check AWD System” light is on?

It is not recommended to drive your vehicle when it is alerting you to a problem with the all-wheel drive system. Continuing to drive your vehicle with the AWD warning light on can cause additional damage to your vehicle and potentially put you and your passengers in danger.

How often should I have my AWD system checked?

It is recommended to have your AWD system checked at least once a year or according to your vehicle manufacturer’s recommendations. Regular maintenance and inspections can help prevent problems with your AWD system and ensure it functions as it is supposed to.

Press the clutch and brake at the same time

Clutch Pedal It often happens that you press the clutch and brake at the same time. Have you ever thought about what happens when you do that? Now is the time! You need to be aware of how your car reacts when you use the brake and clutch at the same time.

Come explore the consequences that arise from your actions.

The Results When You Use the Brake and Clutch at the Same Time

Time clearly shows that the brake and clutch have been used in synchronization. When you brake and downshift together in the right way, things could turn in your favor. On the other hand, if you do it wrong, things could get worse.

Read on to examine both sides of the coin in detail.

1. The Wrong Way

When you apply the brakes in sync with the clutch, it will cause your car to stop immediately. This would be necessary when it is required to stop the car instantly. For example, if a human or stray animal suddenly appears in front of you; you would need to stop the car immediately. You must use the brake and clutch at the same time in such situations.

One must use the brake and clutch at the same time

An important thing to keep in mind is that pressing the brake with the clutch is not at all suitable for your car. The combination of the clutch and brake can lead to excessive fuel consumption, stalling jerks, and wasted energy. Another drawback is the depreciation of brake quality. The brakes, in turn, would wear out easily, increasing risks to your safety while driving.

2. The Right Way

If you are a novice driver, you will need to press the brakes and clutch simultaneously when stopping. One must know that this is not an ideal thing to do. When you want to reduce your speed approaching an intersection or come to a complete stop, a definitive approach must be followed.

The correct step is to brake first, then press the clutch. For example, if you need to reduce your speed, gently press the brake to reach a lower speed. Then, you can press the clutch. This can help you make small stops at approaching signals. Alternatively, when you want to make a complete stop; follow the same procedure by pressing the brakes and then the clutch.

By doing this, you will increase the lifespan of the brakes and clutch while saving on fuel consumption. Refer to the maintenance tips to learn more about advice for increasing the lifespan of the clutch and brakes.

How to Correctly Use the Brake and Clutch at the Same Time?

Using the brake and clutch pedals simultaneously in a car is generally not necessary nor recommended during normal driving. However, there may be situations where you need to press both pedals at the same time, such as during an emergency stop or as part of specific driving techniques. Here is a general guide on how to correctly use the brake and clutch pedals together:

Understanding the Purpose of Each Pedal

• Brake Pedal: The brake pedal is used to slow down or stop the vehicle by applying the brakes.
• Clutch Pedal: The clutch pedal is used to engage or disengage the engine power from the wheels, allowing you to change gears.

Emergency Stops

In an emergency where you need to stop the car as quickly as possible, you may need to press the brake and clutch pedals simultaneously.

Press the clutch pedal all the way to the floor to disengage the engine power from the wheels, preventing the engine from stalling.

Apply firm and progressive pressure on the brake pedal to stop the car as quickly as possible.

Specific Driving Techniques

In some advanced driving techniques, such as heel-and-toe downshifting, you may need to use the brake and clutch pedals simultaneously.

Heel-and-toe downshifting is a technique used to shift to a lower gear while braking, typically in performance driving or spirited driving.

The technique involves using the right side of your foot to brake and the right side of your foot or the side of your other foot to press the accelerator while the clutch is depressed.

This technique requires practice and coordination and is generally used by experienced drivers.

1. Smooth Stop:

• For a smooth stop, it is advisable to press the brake first, then disengage the clutch progressively while you continue to brake.
• This allows the vehicle to slow down smoothly and maintain steering control.

2. Emergency Braking:

• In case of emergency braking, it is crucial to brake as hard as possible first.
• Then quickly press the clutch to prevent the engine from stalling.
• Not disengaging the clutch before braking in an emergency situation can lengthen the braking distance.

3. Downshifting:

• To downshift, it is necessary to disengage the clutch before releasing the accelerator.
• Then press the brake if necessary to slow the vehicle before shifting gears.
• Release the clutch progressively while you press the accelerator.

Important Points to Remember:

• Always apply gentle and progressive pressure on the clutch and brake pedals.
• Never hold the clutch depressed for a long period, as this can damage the clutch system.
• Coordinate your movements between the clutch, brake, and accelerator pedals for smooth and safe driving.

Conclusion

You would now know what happens when you use the brake and clutch at the same time. Always press the brake first, then the clutch to avoid potential wear. Better safe than sorry, and to ensure your safety; driving the car the right way is necessary.

Reasons for water leaks in the car on the passenger side

There are many types of fluids in your car – from fuel in the engine tank to radiator fluid and coolant. So, a fluid leak isn’t really surprising given the volume of fluid contained in a vehicle. Additionally, the car sometimes appears to have a water leak, but that’s not the case. However, you should pay attention when a car leaks water on the passenger side.

Reasons for Car Water Leaks on the Passenger Side

A car needs different types of fluids to operate, but only two systems use water-based fluids. These are the engine cooling system and the windshield washer system.

When there is water on the passenger side of the car, examine these two areas:

1. The Engine Cooling System

This is the first place to start the investigation when you see a car leaking water on the passenger side. The cooling system is highly pressurized, so even a small leak can force antifreeze out.

Furthermore, heating and cooling cycles can deteriorate seals and wear out gaskets and hoses.

2. The Windshield Washer System

The entire system consists of a reservoir, a pump, hoses, and nozzles. The reservoir stores the washer fluid and the pump pumps it to the hoses. Then, the hoses bring it to the nozzles, which spray the fluid onto the windshield.

A crack in the reservoir is the most common cause of a leak. This happens due to the extreme pressure exerted by frozen and expanded washer fluid.

You need to install a new reservoir to fix the problem. Use a low-freezing-point washer fluid to avoid it completely.

Remember that water will only leak when you use the washer. If you notice that the car is leaking water on the passenger side after using the system, you’ll know where to look.

My Car Leaks Water into the Passenger Side Floor When It Rains

Why does rainwater flow inside the passenger side? Well, there can be several reasons.

• Clogged sunroof drains or a loose drain hose. If your car has a sunroof, check its drainage system for these issues. Problems will cause water to seep into the car instead of draining outside.
• The heater core could also be the culprit. Check if the leaking fluid smells like coolant. In this case, the car will overheat or the coolant level will be low.
• A clogged drain in the air conditioning system or a vent. The passenger floor is the endpoint for these drains.

If you think rainwater is leaking through one of the seals, you can perform a water test to find the problematic spot.

Find an assistant to spray water on the car while you stay inside to try to locate the leak. Start from the low point, like the door crack, up to the bottom of the windshield and progress to the roof.

Testing takes time, but it’s the most cost-effective way to find the troublesome spot when a car leaks water on the passenger side.

FAQ

1. Can a clogged sunroof drain cause a water leak on the passenger side?

Yes, a clogged sunroof drain is a common cause of water leaks. When the drain pipes are clogged, water can overflow and enter the cabin, causing leaks.

2. What should I do if I suspect my car is leaking water on the passenger side?

First, locate the source of the leak by inspecting the affected area. Check for damaged seals, clogged drains, or rusty body panels. If in doubt, it’s best to consult a mechanic for a professional assessment.

3. Can a damaged windshield seal cause water leaks on the passenger side?

A damaged or poorly sealed windshield can allow water to enter the car. If you suspect this is the issue, have a professional inspect and reseal the windshield.

4. Is it dangerous if water seeps into my car?

While water leaks themselves are not immediately dangerous, they can lead to issues such as mold growth, electrical problems, and interior damage over time. It’s essential to address leaks promptly to avoid these secondary problems.

5. How can I prevent water leaks on the passenger side of my car?

Regular maintenance is key. Keep sunroof drains clear, inspect weather seals, and promptly repair any rust or body damage. Parking your car in a garage or under shelter during heavy rain can also help prevent leaks.

A faulty air conditioning system can cause condensation buildup, leading to water leaks. If you suspect this is the problem, have your air conditioning system inspected and repaired by a professional.

7. Is repairing water leaks on the passenger side expensive?

The cost of repairs depends on the cause and severity of the leak. Some tasks, like unclogging blocked drains, can be relatively inexpensive, while others, like replacing a damaged windshield, can be more costly. It’s best to get a repair quote from a qualified mechanic.

8. Can I temporarily fix a water leak myself, or should I always consult a professional?

Simple issues like unclogging blocked drains can sometimes be handled by car owners.

However, for complex problems or if you’re unsure of the cause, it’s advisable to consult a professional mechanic or automotive technician to ensure a proper and lasting solution. Temporary fixes may not address the underlying issue.

Conclusion

When a car leaks water on the passenger side, it usually stems from various factors such as blocked drainage systems, deteriorated seals, or other related issues.

It is essential to promptly diagnose and address these potential causes to ensure the ongoing safety and comfort of your vehicle.

To this end, regular maintenance practices, like unclogging blocked drains and inspecting seals, play a crucial role in preventing water leaks!

How to know which wheel bearing is faulty?

Wheel bearings are essential for the wheels to function harmoniously with the hub and tires. There is one bearing per wheel, and it is rare for all of them to fail at the same time. How to tell which wheel bearing is faulty?

Well, we will discuss how to discover the faulty one and what they actually do to keep the wheel assembly together.

What is a wheel bearing?

Before delving into the symptoms of a bad bearing and ways to identify which one is defective, you need to know what it is and its functions.

A wheel bearing is a metal ring housing a number of steel balls. The ring, called a race, fits into a hub, which is a hollow metal piece at the center of the wheels.

The hub rolls on a metal axle shaft to reduce friction when the wheels rotate. These ball bearings are the most common type in today’s vehicles. There are also ball bearings and precision roller bearings.

Wheel bearings support the entire weight of a vehicle and do not have a constant source of lubrication. For these reasons, they endure a lot of abuse and wear out over time.

How to tell which wheel bearing is faulty?

Every system in an automobile consists of several small components that must function and be integrated together for the car to run smoothly.

But like everything else, these parts are subject to abuse and show warning signs when they are about to fail.

Wheel bearings also exhibit certain symptoms when they cannot function fully and are about to fail. But how to tell which wheel bearing is faulty: front or rear?

All types of wheel bearings show similar symptoms when failing. Here is how to tell which wheel bearing is faulty:

Pay attention to noises

A grinding noise coming from the tires indicates overused bearings that do not have enough lubrication to prevent the grinding friction between metal parts.

The noise intensifies when the vehicle accelerates and it comes from either the front or the rear, indicating the position of the bad bearing.

Sometimes it can be a rumbling when you drive on a straight road and it intensifies once you make a turn. Here is how to tell which wheel bearing is faulty when turning, as the opposite side of the turn is the affected area.

A click also requires attention, as it likely comes from a broken bearing in the hub.

If a bearing is the cause, the noise rotates faster with acceleration. To identify which bearing is responsible, slow down the car and gently sway it.

If the click is muffled when you move to the left, it is likely that the right wheel bearing is broken.

Check the tires.

The condition of the tires is another simple way to tell if there is a problem with the bearings. If a tire wears unevenly, it is probably because the wheel bearing attached to it is damaged.

Tires will show signs of wear over time. It is completely normal for all of them to deteriorate at the same rate.

Wobbly wheels

Another symptom related to damaged bearings is a wobbly wheel. In this case, the car feels loose or you find the steering less responsive, to be precise, while driving.

When this happens, check each wheel by lifting the vehicle. If the wheel assembly moves back and forth, the wheel bearing attached to it is definitely damaged.

Unstable wheels can also be the result of other problems, such as broken suspension or a misaligned chassis. A mechanic can identify the exact reason by performing a road test.

Stiff wheels

Just like loose wheels, stiff wheels are another safety issue and indicate bad bearings. To find out which bearings are responsible, you need to lift the car with a jack and check the front and rear wheels.

Simply grab the tires and spin the wheels. A rotation without effort means they are fine, but if one of them is stiff, its bearing must be broken.

Pulling to one side when braking

Besides a faulty bearing, this problem can result from a number of faulty components, including damaged brakes, a worn rotor, a faulty equalizer, or a broken rotor.

However, if the cause is a broken bearing, it will eventually lead to loose brakes. Whenever you brake, the car acts as if it has a mind of its own and pulls in a specific direction. Examine the bearings on the side towards which the vehicle pulls.

FAQ

1. Can a bad wheel bearing cause other problems if not replaced?

Yes, a bad wheel bearing can lead to bigger problems if not replaced promptly. These include:

• Damage to the wheel hub assembly.
• Uneven tire wear, which can affect handling and traction.
• Increased stress on other suspension components.
• Safety issues as it can lead to loss of control in extreme cases.

2. Is it difficult to replace a wheel bearing?

Replacing a wheel bearing can vary in difficulty depending on the make and model of your vehicle. Some bearings are relatively easy to replace, while others may require specialized tools and knowledge.

It is recommended to entrust the job to a qualified mechanic if you are not sure about your DIY skills.

3. Are there maintenance tips to avoid wheel bearing problems?

• Even though wheel bearings wear out over time, you can extend their lifespan by:
• Keeping your wheels properly aligned and balanced.
• Regularly inspecting and lubricating the wheel bearings according to your vehicle’s maintenance schedule.
• Avoiding overloading your vehicle beyond its weight capacity.

4. How much does it cost to replace a wheel bearing?

The cost of replacing a wheel bearing varies depending on factors such as the vehicle’s make and model, labor costs in your area, and whether you use original or aftermarket parts. On average, it can cost between $100 and $600 per wheel.

5. Can I drive with a bad wheel bearing?

It is not recommended to drive with a bad wheel bearing. Continuing to drive with a faulty wheel bearing can lead to safety risks, further damage to your vehicle, and more expensive repairs.

6. How long does a wheel bearing typically last?

The lifespan of a wheel bearing varies, but it typically lasts between 85,000 and 100,000 miles (137,000 to 161,000 kilometers) or more under normal conditions. However, factors such as driving habits and road conditions can affect their longevity.

7. Can I replace just one wheel bearing if it’s faulty, or should I replace both sides?

While it is not mandatory to replace both wheel bearings at the same time, it is often recommended to do so. If one wheel bearing is faulty, the other may not be far behind in terms of wear. Replacing both can help ensure uniform performance and safety.

Remember that if you suspect a bad wheel bearing, it is essential to have it inspected and replaced by a qualified mechanic to maintain your vehicle’s safety and performance.

I hope you now know how to tell which wheel bearing is faulty. Just detect the symptom and perform a simple task to find out which bearing is at fault.
