Should the Tensioner Pulley Be Replaced When Changing the Belt? It is recommended to replace the tensioner pulley along with the belt. The details are as follows: 1. Belts: There are two belts in a car, the timing belt and the accessory belt. The replacement interval for the timing belt is similar for almost all cars, approximately every three years or 60,000 kilometers. 2. Replacement: During the replacement, the tensioner pulley and the idle pulley should be replaced at the same time. This is because the lifespan of the belt and the tensioner pulley is nearly the same. Once the belt reaches the end of its lifespan, even if the tensioner pulley is still functional, it is uncertain how much longer it will last. 3. Safety: It is not advisable to replace the tensioner pulley after another 20,000 kilometers because the labor cost for belt replacement is very high, equivalent to paying twice for labor. For safety and cost-saving reasons, it is best to replace them simultaneously. However, the water pump does not need to be removed and replaced.
