Two reasons:
1. Belt tension is not sufficient and the belt is adjusted too loosely, causing slippage;
2. If the belt slips again after tensioning is complete. adjusted, check the belt itself for cracks and aging (rubber will harden after prolonged use and tends to slip); check if there are foreign objects inside the pulley groove (if there is grease).
The car belt is squeaking, just pour a little water on it and everything will be fine! But the problem persists on the next startup!
Usually the belt is stretched due to long-term use and slippage.
The main cause of engine belt slippage is loosening or aging of the engine belt. Factors that can cause the engine belt to come loose include improper adjustment of the t system.engine belt tension or insufficient adjustment. elasticity of the tensioner wheel. At this point, the motor belt should be loose or aged. First adjust the tension force of the engine belt tensioner. If this has no effect, replace the tensioner.
Check if it is the noise of the cylinder block. Otherwise, it can be determined that it is related to the car's starting system.
When checking, check if the belt is broken or has burrs; pay attention to whether the position of the starter is deviated, or whether the belt connecting the starter is aging or winding.
Timely inspection and maintenance, as well as minor car problems should not be ignored.

Car maintenance knowledge:
Antifreeze It is best to use the agent all year round. In addition to the antifreeze and cooling functionsment, antifreeze also has cleaning, rust removal and anti-corrosion functions, thereby reducing corrosion of the water tank and protecting the engine. Be careful to choose the right color of antifreeze and not mix them.
The function of the brake system is closely related to brake oil. When inspecting and replacing brake pads, pads and other hardware, remember to see if you need to add and replace brake fluid.
To ensure that the car runs smoothly, check the transmission oil frequently, whether it is gear oil or automatic transmission oil. Pay attention to the type of oil, which is usually high.
