How To Judge That The Tensioner Is Broken

Symptoms of damage to the tensioner include sudden increase in engine noise during rapid acceleration (especially when the speed is around 1500), engine timing jumps, disturbance of ignition and valve timing, engine jitter, and difficulty in ignition (severely unable to hit the car directly) ). When the above situation occurs, check whether the tensioner has been damaged.

Experienced "veteran drivers" can tell whether the tensioner is good or bad by feeling the tightness with their hands, or by sound. The tension pulley is composed of a fixed shell, a tension arm, a wheel body, a torsion spring, a rolling bearing and a spring sleeve. The tension pulley can automatically adjust the tension force according to the different tightness of the belt, thereby making the transmission system stable Safe and reliable.

The tensioner is a vulnerable part of the car body. The rubber belt will naturally be stretched and elongated after a long time. With the tensioner, the belt runs more smoothly, the noise is less, and it can prevent slipping. . The tensioner is generally replaced together with the timing belt to avoid worries.
