A: It will affect the line. In general, for example, an abnormal sound or a strange noise may be the failure of the tensioner.
 

tensioner acts on the timing belt or timing chain of the engine, guiding it and tightening it so that it is always in the best tension state. It is generally divided into two types: hydraulic pressure and mechanical, which can automatically adjust the tension of the timing belt and the timing chain.
 

The tensioner is a consumable part of the automobile and other parts. The belt is easy to be stretched for a long time. Some tensioning wheels can automatically adjust the tension of the belt. In addition, the tensioning belt runs more smoothly. The noise is small and it can prevent slipping.
 

The role of the tensioner is to adjust the tightness of the timing belt, which is usually replaced with the timing belt to avoid worries. Other parts do not need to be replaced, as long as regular maintenance.
