What Sound Does a Faulty Tensioner Make?

[JustinAnn]

A faulty tensioner typically produces a buzzing or squeaking abnormal noise. Symptoms of a damaged tensioner include increased fuel consumption, lack of power, engine knocking, and other malfunctions. The tensioner's function is applied to the engine's timing belt or timing chain, providing guidance and tension to maintain them in an optimal tensioned state. Tensioners are generally categorized into hydraulic and mechanical types, both capable of automatically adjusting the tension of timing belts and chains. The removal method for a tensioner involves: driving the vehicle onto a lift, disconnecting the battery, removing the hose bracket, inserting a tool into the dedicated opening of the belt tensioner, then using a wrench to turn the automatic belt tensioner clockwise and loosening the engine auxiliary system belt. Finally, loosen the fixing screws according to the belt tensioner wheel to be removed.
