After the car started in the morning, the belt of the generator squeaked back

It may be because the belt has slipped on the generator, and the belt and the pulley are violently rubbed and vibrate, making a certain frequency of sound.

The main reason for belt slippage is belt looseness or aging, among which the factors that can lead to belt loosening are improper adjustment of belt tensioner or insufficient elasticity of belt tensioner, at this time, the tension of the belt tensioner should be adjusted first, and if there is no effect, the tensioner should be replaced.

Belt aging mainly refers to the gradual hardening and loss of elasticity of the belt during long-term use, and the friction between the belt and the pulley is reduced.

In this case, only the belt can be replaced.

A crack indicates that the belt is aging. If the timing belt needs to be replaced immediately, the engine belt can continue to be used for a while.

This is the reason for the sagging of the belt and the need to re-tighten the belt.

The sound of friction between the belt and the pulley occurs when the belt slips, causing the generator to run and lose its rotation.

Especially when the engine accelerates, the squeak will be more obvious, which is the key to judging the slack of the belt.

When the car started in the morning, the belt of the generator creaked. At this time, the belt is relatively cool, and there is a certain amount of clearance on the belt, which will make a squeaking sound when the driving wheel rotates. Check whether the squeaking sound is made by the belt, you can take a bottle of water and sprinkle it on the belt, if the sound disappears, it is the sound of the belt, which is the hidden danger of the belt, and it is recommended to replace it in time.

Summary. Hello, dear, the reason why the car clicks after changing the generator belt is that the belt is too loose or too tight and the water pump is ringing 1The friction between the timing belt and the timing cover creates noise, which can damage the timing belt in advance, and if it breaks, it can damage the engine valves and require major repairs.

2.The sound of the water pump is abnormal. However, most of them are used when the car is hot.

If the sound is not loud, it can be ignored. When you change the timing for 9 weeks or 6 years, replace the generator's belt or the generator's tensioner. As long as the sound is not loud, it can be ignored.

And it does not affect the service life of the belt. Even if it is broken, it can be replaced immediately before the battery dies. In general, other parts are not lost.

Only when the direction is broken, the booster pump does not work.

After the eight-generation Accord changed the generator belt, the cold car was always clattering after starting.

Hello, dear, the reason why the car clicks after changing the generator belt is that the belt is too loose or too tight and the water pump is ringing 1The friction between the timing belt and the timing cover produces a noisy sound, which can damage the timing belt in advance, and if it is broken, it will damage the engine valve and need to be overhauled. 2.

The sound of the water pump is abnormal. However, most of them are used when the car is hot. If the sound is not loud, it can be ignored.

When you change the timing for 9 weeks or 6 years, replace the belt of the hair slider motor or the tensioner of the generator. As long as the sound is not loud, it can be ignored. And it does not affect the service life of the belt.

Even if it is broken, it can be replaced immediately before the battery dies. In general, other parts are not lost. Only when the direction is broken, the booster pump does not work.

The squeak after replacing the timing belt can be caused by an overtight timing belt, damaged tensioner pulleys, abnormal valve clearance, or offset or loose timing wheels. When the car can't step on the accelerator and can't fill up the fuel, the crack return energy will cause the timing belt to age, and the engine will shake seriously when the car is idling, indicating that the timing belt is seriously damaged and needs to be replaced.

Did you ring before you changed or did you just ring after you changed your belt?

It only rings after a new belt.

The engine clatter after the timing belt is changed is that the timing belt is too tight, the tensioner wheel is damaged, the valve clearance is abnormal, and the timing wheel is deviated or loose.

I thought it was a generator, and after checking it, I found that there was no problem.

It is recommended that you check the timing and valves.

Do you need to change the tensioner?

You can replace it to see that a damaged tensioner can also cause a click.

It has nothing to do with the booster pump.

It doesn't matter much. Oh oh ok thank you.

The main reasons are that the timing belt is too tight, the tensioner wheel is damaged, the valve clearance is abnormal, and the timing wheel deviates or loosens.

After the car starts, the engine has a squeaky belt, which is likely to be caused by the wear and aging of the belt, the slippage of the engine or directional power pump leakage, and the temperature becomes low.

Socio-economic development is getting faster and faster, people's quality of life is also improving, people must understand the situation of the vehicle in the process of driving the vehicle, if the engine belt squeaks, we must pay attention to it in time, go to the local 4S shop for repair, so as to better prevent accidents.

The belt is worn and aged, resulting in a squeaky sound

As we all know, the belt must be tightly fitted with gears in order to work normally, generally speaking, there will be aging in the use of the belt, at this time only need to be replaced in time, but we need to pay attention to the fact that when replacing the belt, we must pinch the belt with the thumb and index finger, and it is appropriate to be able to twist the upper side of the motor belt 90 degrees after exerting force, so as to better ensure that the abnormal sound of the belt disappears when the car is cold.

Oil leaks from the engine or directional booster pump and causes a squeaking sound on the belt

In the process of using the vehicle, each component will have a certain amount of wear and tear, if the direction of the booster pump or the engine leaks oil and causes a lack of lubrication, there will also be belt slippage symptoms, often in the past not only will there be a squeaky sound, and even the belt will break to cause traffic accidents, at this time you can choose to fill in time with new oil or replace a new oil pump.

The temperature is too low, causing the engine to creak and squeak

Most of the belts are made of rubber, if the temperature is too low, the rubber will also become hard, and there will be abnormal noise when the car is cold, if you want to avoid this situation, you can choose to spray lubricating substances, which can better avoid the generation of abnormal noise, I hope everyone can understand their vehicles in life, and repair them in time once there is a problem.

The squeaking of the engine belt may be caused by the wear and aging of the belt, and it can be replaced in time. The breakage of the engine timing belt will cause the engine to fail to run normally, seriously affect the working condition of the engine, and will break the valve and piston as well as the two banks. Engine timing belts need to be replaced in a timely manner when cracks and aging.

The following are the replacement steps of the timing belt: 1. Disassemble the valve chamber cover, disassemble the crankshaft pulley, and remove the timing chain shell; Rotate the crankshaft, turn the crankshaft to the top dead center of a cylinder, screw the crankshaft fixing screw, and fix the crankshaft; 2. Rotate the intake and exhaust camshaft, there is a groove at the rear end of the camshaft, align the grooves of the two camshafts in a balanced manner, and snap the special tool into it; 3. Remove the old chain and replace it with a new one. The crankshaft pulley is also without a slide key, and when installed, there is a round hole on the pulley, which is aligned in the groove above the chain shell; 4. The crankshaft position sensor can be adjusted, and the gap should be adjusted in place during installation, otherwise the fault code will be reported; Both the crankshaft sprocket and the pulley rotate freely.

Belt wear, belt aging, belt model and vehicle regulations are not the same, engine oil leakage, automatic tensioner damage or manual fixation tensioner damage,

It is very likely that the belt is seriously worn or aged, and you need to go to the 4S shop to find a professional maintenance personnel to check, and then decide whether to replace or in-depth check the fault of the surrounding parts.

Why does the belt make an abnormal noise when the car starts? What are the reasons for this?

Let's talk about buying a car, using a car, maintaining a car, and repairing a car.

Hello, this is the abnormal sound of the belt caused by the belt being too loose, it is recommended to tighten the belt tensioner.

As soon as the car starts, the abnormal sound of the belt may be the sound of friction caused by the belt being too tight, but after the engine is running, there will be no sound, and it will be fine.

One is that the cold car belt may be stiff, and the other is caused by the loosening of the belt, if it is only the sound when starting is the first reason.

One is rust, the other is that the belt is a little loose, and the belt will sound when the car is cold.

I think that if you leave it overnight, there will be some rust on the belt tensioner or pulley! Of course, the belt is also loose.

Sometimes it's not necessarily a belt problem. You go and see if there's anything wrong with the engine!

The belt gum is dry and aging, and it is recommended to replace it.

It is recommended to check to see if there is any problem with the belt.

First, the aging of the transmission belt will cause abnormal noise when the vehicle starts. Because the belt is the rubber inside, the friction after aging is not as good as before, so it will have a certain impact on the transmission of power, which will cause the occurrence of slippage, after a period of slipping, the rubber will gradually soften due to friction heat, and the sound will disappear.

Second, insufficient belt tension will cause abnormal noises when the vehicle starts. In fact, when the belt tension is insufficient, the belt will also be very prone to slippage like aging. Most of the belts used in automobiles are automatically adjusted tight, it presses the belt through a large spring design, and then realizes the adjustment of the belt tightness, when the belt is too loose, the friction will also be reduced, at this time, it will produce abnormal noise due to skidding.

Thirdly, severe belt wear will cause abnormal noise when the vehicle starts. When the belt of the car is severely worn, the contact area between the belt and the pulley is greatly reduced.

In fact, in fact, there are many abnormal noises in cars, and it is not only the abnormal noise of belts. And judging whether the car is a belt abnormal noise is also very simple, that is, when we carry out the cold start operation, sprinkle some water on the belt, if the start does not sound is the belt abnormal noise, because the water can be lubricated, so even if the belt is slipping, the noise will disappear at this time.

In most cases, the belt is loose, in this case, it is best to go to the repair shop to adjust the belt tension, because the belt will produce a screaming sound when the belt slips, once the belt slips, the belt will be further elongated due to the friction and high temperature, and the slippage will be more serious, and it will enter a vicious circle. Therefore, timely adjustment of belt tension is the key.

On the issue of abnormal noise, it is difficult for ordinary car owners to distinguish which ones are fault abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. Models equipped with turbocharged engines are different; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

How to identify the sound of a car:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the slag-burning car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of the beam structure of each section of the car when it is working will make a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, it is necessary to distinguish between normal sound and abnormal sound first. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod such as a source piece as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire to reduce the sound to meet the needs of diagnosis. The auscultation site should be kept quiet to minimize human interference.

What is the squeak of the car generator belt This is caused by the relatively smooth grinding of the joint surface of the belt and the pulley, which generally occurs when the engine speed changes rapidly, and sometimes the increase in the load of the accessories driven by the belt will also cause the motor belt to squeak. Solution: 1. Check whether the accessories driven by the belt are damaged, stuck, loose or the power of the accessories has increased; 2. Replace the belt, or use 100 gauze to polish the joint surface of the pulley and the belt (light grinding is enough); 3. Temporarily solve the tomb can be used to drop 1-2 drops of engine oil on the joint surface of the belt and the pulley (it will not affect the slippage of the belt).
