If you hear an abnormal "sizzling" noise while driving, it is due to an engine belt problem, because the abnormal "sizzling" noise is mainly caused by aging of the engine belt assemblies, or by the problem of the tensioner roller. makes the belt too loose, causing abnormal friction and noise, belt slippage, etc. If a similar abnormal "sizzling" sound occurs, look for the main belt assemblies and tensioner pulleys inside the engine, such as the engine timing belt, generator belt, circulating water pump belt, air conditioning belt, power pump belt, etc. The problem causing this abnormal noise is the abnormal noise of the motor belt. It is caused by the gentle grinding of the joint surface of the belt and pulley. . This usually happens when the engine speed changes quickly. Sometimes, the increased load on belt-driven accessories also causes belt noise.
How to solve the problem of abnormal noise in the motor belt
1. Check belt-driven accessories for damaged bearings, stuck, loose, or loss of engine power. accessories have increased.
2. Replace the belt or use #100 gauze to polish the joint surface of the pulley and belt (just buff it lightly).
3. As a temporary solution, you can drop 1-2 drops of engine oil on the joint surface of the belt and pulley (this will not affect the sliding of the belt)
The best way to determine which belt is which oil is flowing on the belt. If the generator belt is noisy and this is more obvious after turning on the headlights, you need to remove the generator belt and turn the generator pulleyator to see if the generator is working. turns smoothly. If the generator is operating normally, you can check if there is no power to the battery, as improper battery storage will increase the load on the generator.
The above explains the causes of abnormal noise in the engine belt and how to solve the problem of abnormal noise. I hope this is helpful to you!
