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 is the relevant content explaining why the engine belt makes abnormal noise and how to solve the problem. Hope this is helpful!
What is the reason for this problem. Geely generator belt to make noise when it rains?
The sound produced by friction between the timing belt and the timing cover. Such problems can damage the timing belt in advance. If it breaks, it will damage the engine valve and require servicing. The water pump makes an abnormal noise. But most of them happen when the car is hot. If the noise is not loud, you can ignore it and replace the alternator belt ou the alternator tensioner as well as the timing change at 9 weeks/6 years. As long as the sound is not loud, you can ignore it. Will not affect belt life. Even if it breaks down, you can replace it immediately before the battery runs out. Generally there will be no loss of other components. Even if the power steering pump is disconnected, it will not work. How to confirm if the generator belt makes abnormal noise: Pour water on the generator belt before starting, turn on and the chirping noise disappears. After the water dries for 1 or 2 minutes, the chirping will reappear. Pour a little more water and the abnormal noise disappears again.
Depending on how your vehicle is used, this is a question of belt tightening. It is recommended to go to the repair shop to adjust it. Secondly, you also need to check whether the belt. is aged,has a hard surface and has cracks and other phenomena, if it exists, it is recommended to replace it. As for the generator voltage, there is a normal voltage fluctuation. According to the values above, there should be no problems.
