If the car belt is loose, will it cause a loud sound?

Yes, and if not treated in time, it will affect the water pump (wheel), generator (wheel), and air conditioning compressor.

wheels), steering power pumps (wheels), air compressors, etc., which affect the overall working condition of the engine, and even damage the engine or cause safety accidents.

For the car, the limiting screw of the wheel without load should be adjusted to restore the belt to a suitable tension.

Trucks, in general, adjust the limit screws of the generator to adjust the tension of the belt.

The belt should be replaced in time due to wear and aging.

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.

If you've driven almost 20,000 kilometers and haven't changed your belt before, you should basically replace your belt now. Don't wait until the belt is broken to change it.

How to judge the abnormal noise of the engine belt:

The first thing to do is to check the engine belt. If there are multiple belts in the car, you can not judge which belt is the problem, you can start the car first, and then pour some water on the belt, if there is an abnormal sound to disappear, it means that the belt is a problem, you can see whether it is loose or the quality is not good.

If the engine belt makes abnormal noise, pouring water is to increase its viscosity, which actually improves the viscosity of the belt. But when the water dries, the belt will return to its original state, which is the principle of belt watering.

It may be because the engine belt slips on the generator, air conditioning compressor, and power steering pump, and the engine belt and the engine pulley are violently rubbed and vibrate, making a certain frequency of sound.

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

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

This situation requires the replacement of the engine belt.

There is an abnormal sound in the engine belt of the car, which means that the belt has aged.

The breakage of the engine belt after abnormal noise will lead to the failure of the car's air conditioning system, power steering system, power generation system and other fault phenomena.

The engine belt is connected to these components, and the power of these parts comes from the engine, and the transmission of power is transmitted through the engine belt. Abnormal noise in the engine belt and then breakage can cause these parts to lose power**. There are some failures such as the air conditioner compressor not working, the generator not working, and the power steering pump not working.

Therefore, if there is an abnormal noise in the engine belt, it needs to be checked as soon as possible to prevent the above faults after the engine belt breaks.

This is caused by the relatively smooth grinding of the joint surface of the belt and pulley. It usually occurs when the engine speed changes rapidly, and sometimes the belt rings when the load of the attachment driven by the belt increases.

Solution: 1: Check whether the attachment driven by the belt is damaged, stuck, loose or the power of the attachment has increased.

2: Replace the belt, or use 100 gauze to polish the joint surface of the pulley with the belt (light sanding is fine).

3: The temporary solution can be 1 2 drops of oil on the joint surface of the belt and the pulley (it will not affect the belt slippage).

The best way you can tell which belt is to drip oil on the belt.

If the generator belt rings and the headlights are turned on, you need to take off the generator belt and turn the motor pulley to see if the generator rotates smoothly.

If the generator is normal, you can check whether the battery is not storing power, because the battery storage is not good will increase the load of the generator.

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

The engine belt makes an abnormal noise, the automatic tensioner is not working, what should we do?

What are the causes of abnormal belt noise?

If the belt is due to a long working time, it can be adjusted, provided that there is an adjustment device, if it is an abnormal noise caused by the aging of the belt, then this situation can only be solved by replacement

Hello, the car belt can only change the belt, it is best to go to a professional place to check whether it is the belt or the front tensioner or idler pulley, etc.

Generally, when the car starts cold, you hear a piercing squeak, and the sound disappears after the car is hot This is generally the case that the belt is loose, and you can solve the problem by tightening the belt in the 4S store I don't know how many kilometers your car has run Whether the belt is aging and cracked The belt of the Tiida car will age and crack when it is 4-50,000 kilometers, it is recommended that you check it, simply apply oil, or spray anti-rust liquid to solve the problem temporarily Can not be fundamentally solved Oh I hope it can help you

If the belt is new, remove the belt and shake it up and down with your hands, left and right, whether the belt tensioner bearing feels loose, and it should be worn out after running for so long. As long as it is a bearing connected to a belt, it is possible.

Always the sound caused by the slippage of the nest of the generator with the belt, and the friction will slip as soon as it heats.

It is possible that the nest of this generator is slightly offset from the other wheels in the same group, and the force will ring.

When you have an abnormal belt noise, all kinds of methods have been tried, all kinds of suspicious things have been changed, are new and ringing, you may wish to carefully use things to move the belt on both sides of the belt pulley when rotating, and the sound becomes louder to the outside of the engine, that is, the generator, tensioner and other components are too tight, and the sound is too loose to the inside of the engine....This will cause the pulleys to not be on the same line, resulting in a greater coefficient of friction, at this time it is good to tighten or loosen the tensioner or generator, hoping to help the car gods who cannot solve the problem in various ways

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.

Most belt auto tensioners have a set of belt wear length indication signs somewhere along the direction of the chute between their bottom and the tensioner arm. The sign consists of a pointer and two or three markings, which indicate the operating range of the belt tensioner. If the pointer is out of this range, then the belt is probably stretched too long and should be replaced.

In cars where there is no automatic belt tensioner installed, a standard belt elongation gauge is used to measure the middle of the two pulleys. If there is a discrepancy from the standard value, it is better to replace the belt.

If the elongation of the drive belt does not exceed its class limit, then you should focus on it if your car is fitted with an automatic tensioner. First, start the engine, load the auxiliary drive configuration as much as possible, and then observe the belt tensioner cantilever; While the engine is working, there should be a small amount of displacement in the belt tensioner overhang. If the belt tensioner cantilever does not move, turn off the engine and manually move it within the working stroke of the belt tensioner suspension, which is about a centimeter of displacement.

If the cantilever of the belt tensioner cannot be moved, it indicates that the belt tensioner has failed and should be replaced in time; If the displacement of the cantilever of the belt tensioner exceeds about centimeters, it means that the spring load is too small, which will make the belt slip.

If the belt is not over-elongated and the automatic tensioner is working well, see if the working surface of the belt is as smooth as a mirror. This is a typical slippage phenomenon caused by excessive wear of the belt under load, and the paint peeling off the surface of the pulley is the best proof of the slippage.

If the belt squeaks, it often occurs in wet weather, and the surface of the belt and pulleys is relatively smooth. Let's do the same experiment: let the auxiliary configuration work under load while the auxiliary configuration is sprinkled with water on the belt, and if there is a noise, the belt is replaced.

Long screams or shrill noises:

Although the surface of the pulley can be stained with dirt such as sand particles or if the used belt is installed in the opposite direction, it can also cause the belt to make a long squealing or screeching noise, but it is usually caused by improper assembly of the auxiliary device.

Generally speaking, it may be that the belt of the car is worn out, and it is recommended that you replace it with a new belt.

When you have an abnormal belt noise, all kinds of methods have been tried, all kinds of suspicious things have been changed, are new and ringing, you may wish to carefully use things to move the belt on both sides of the belt pulley when rotating, and the sound becomes louder to the outside of the engine, that is, the generator, tensioner and other components are too tight, and the sound is too loose to the inside of the engine....This will cause the pulleys to not be on the same line, resulting in a greater coefficient of friction, at this time it is good to tighten or loosen the tensioner or generator, hoping to help the car gods who cannot solve the problem in various ways

Summary. Yes, the belt is new, and it will not be after a period of running-in.

The main reason is that the belt is new, so it will lead to wear and tear for a period of time, and after the run-in is good, this sound will be removed.

After the car starts. Spray some watch plate wax on the belt, and the colder the weather, the louder it is. You can also check the tightness of the belt

The car belt has just been replaced.

The main reason is that the belt is new, so it will lead to wear for a period of time, wear for a period of time, and after the run-in is out of draft, this sound will be removed. After the car starts. Spraying a little bit of watch wax on the belt is not respectful, and the colder the weather, the louder it is.

You can also check the tightness of the belt

That's the problem of belt tightness, and it shouldn't have been run-in for 3 months.

It would be nice to adjust the repair shop.

I've run a repair shop myself, and it's a belt problem

It has nothing to do with the new water pump, right, the repair shop said that it is not loose, and the socks of the pump wheel can't be broken, let the change of this round and that round When I came, there was no sound at all, and my mind trembled, and I asked what was going on.

It's not that problem, it's a problem with the belt, let him check it carefully, try to wipe something on the belt, and don't need to replace the booster pump wheel.

I'll go to him tomorrow, if he doesn't want to open it after wiping something, will it be wiping something?

Just spray the table plate wax.

If you don't want to open it after wiping something, will it ring?

It's possible, I didn't see the actual car, so it's still possible, if it sounds again, you can tell me, I'll give you another tip.

Brother, why did you talk about the last one<>

Okay, I'll take a moment

1. If the belt of the automobile generator is loose, it will cause the generator to charge the battery insufficiently, which will affect the normal use of the battery. The car generator is the main power source of the car, which can supply power to the electronic equipment in the car and store power to the battery. One thing to note here is that the engine needs to be running normally (above idle) for the generator to be able to supply power properly.

2. The car has a timing belt and a motor belt, if the motor belt is loose, then the charging will be affected. If it is a timing belt, then the car power will decrease. And the transmission power is insufficient, resulting in poor heat dissipation, so that the engine power output becomes poor, energy consumption increases, and fuel consumption also rises.

There is some abnormal noise in the belt of the engine. The engine's belt should be well inspected. Probably because the engine's belt is loose. It should be thoroughly checked.

In such a situation, I think I should go to the 4S shop in time to repair it, and I should also find the fault of the engine and replace it in time.

You should stop driving immediately, check if the engine is stuck, and if you can't find the cause, go to a 4S shop to repair it.

You can change the belt of the car, and then clean the engine in time to improve the performance of the engine.

Loose belts in car generators will affect power generation.

The generator of the car is to supply power to the electronic equipment on the car during the use of the vehicle (except in the idle state), as well as to charge the battery, if the belt on the generator is too loose, it will cause the generator to charge the battery insufficiently, thus affecting the normal use of the battery.

The car generator is the main power source of the car, and its function is to supply power to all electrical equipment (except the starter) when the engine is running normally (above idle), and at the same time charge the battery.
