The belt tensioner pulley is often important on car engines. Generally, if the tensioner fails, the assembly needs to be replaced. The tensioner acts on the timing belt or timing chain of the engine to guide and tighten it so that it is always in the best tension state. . If the tensioner wheel is broken, it will affect the timing of the engine, the timing of ignition and gas distribution will be disordered, the engine will shake and ignite difficult, and the car will not be able to hit the car in severe cases.
How to judge that the tensioner is broken in life? Remember these points:
1. If the tensioner is broken, there will be noise at 1400-1500 rpm, and the noise will be louder when the power consumption is large.
2. If the tensioner is broken, the resonance will be very obvious, the noise will be very loud during rapid acceleration, there will be noise, and the power will be insufficient.
3. If the tensioner wheel is broken while driving, there will be no brakes, and no direction and the consequences are very serious.
4. If the tensioner wheel is not very bad, then the car will make a creaking sound when it starts.
