How to Solve Abnormal Car Belt Noise

This may be because the belt has slipped on the generator and the belt and pulley are rubbing and vibrating violently, producing a sound of a certain frequency.

The main cause of belt slippage is belt loosening or aging. Factors that can cause belt slack include improper belt tensioner adjustment or insufficient tensioner elasticity. The belt tension must be adjusted first. If that doesn't work, replace the tensioner.

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, the belt can only be replaced.

How to judge the abnormal noise of the motor belt:

First of all, check the motor belt. If there are morers belts in the car and you cannot determine which belt is the problem, you can first start the car and then pour water on the belt. If the abnormal noise disappears, there is a problem with this belt. and you can check. Maybe it's loose or the quality is bad.

The motor belt makes an abnormal noise. Dousing it with water will increase its viscosity, which effectively improves the viscosity of the belt. But after the water dries, the belt will return to its original state. This is the principle of belt watering.

The reasons for the abnormal noise of the motor belt are as follows:

1. It is caused by the gentle grinding of the belt joint surface. belt and pulley. This usually happens when the engine speed changes quickly. Sometimes the increased load on belt-driven accessories also causes a clicking noise.hemmed.

2. The noise of friction between the timing belt and the timing cover. Such problems can damage the timing belt in advance if it breaks, this will certainly damage the engine valve and require servicing.

3. Check whether the oil pump is damaged, resulting in insufficient oil supply, resulting in failure of the timing chain to be lubricated in time, resulting in abnormal noise.

Detailed information:

1. Mileage and replacement cycle, general engine belt replacement. mileage is five years or 100,000 kilometers. This duration and mileage are estimates only. The quality of the belts of different models is also different.

2. If the belt makes an abnormal squealing sound when starting a cold car, simply pour some cold water on the belt andremember not to drip lubricating oil. If the abnormal noise disappears, it means the problem is related. the belt is the cause.

3. Engine oil, gear oil and other corrosive liquids accidentally spilled onto the belt should be replaced even if washed, as this will harden the belt and over time damage the engine. If the belt breaks suddenly, it will affect driving safety. When maintaining, be sure to pay attention to this point to avoid dripping on the belt.
