Can You Still Drive with a Noisy Tensioner Pulley?

[StAnastasia]

You should not drive with a noisy tensioner pulley. The tensioner pulley contains bearings, and if there is abnormal noise, it indicates that the bearings are damaged. This may lead to timing belt/chain misalignment, ignition and valve timing issues, affecting the normal operation of the vehicle. Below is additional information: 1. Maintain Tension: The tensioner pulley directly contacts the timing belt or chain to ensure proper tension during operation, preventing slippage, misalignment, or loosening, and reducing wear on the sprockets and chain. 2. Adjust Tightness: It is used to adjust the tightness of the timing belt, but its lifespan is relatively short. Many vehicles experience tensioner pulley failure before the belt wears out. Generally, the tensioner pulley is replaced along with the timing belt. 3. Replacement Interval: It is recommended to replace the tensioner pulley every 3-5 years or 80,000-100,000 kilometers. Refer to the vehicle's maintenance manual for specific replacement intervals.
