Symptoms Of A Broken Belt Tensioner

The drive belt tensioner is a kind of car tensioner, which is used in the engine timing system software of the engine to adjust the tightness of the timing chain/transmission chain.

It will continue to cause common failures such as vibration, increased fuel consumption, accelerated fatigue, and engine knocking.

If there is a problem with the tensioner of the transmission belt, it should be replaced immediately. If it is not replaced immediately, it is likely to cause the engine to vibrate, it will be difficult to fire, and the car will not start in serious cases.

For the actual replacement time, refer to the vehicle maintenance manual. When replacing the timing chain, it will be replaced together with the tensioner. The price of spare parts is around 500-60 yuan. If a set is replaced and the labor cost is added, the replacement cost will be around 1,000 yuan, and the car 4S shop will be relatively more expensive. , but more assured.
