Does a Noisy Tensioner Pulley Damage the Car?

[ElliottLynn]

A noisy tensioner pulley can damage the car and affect its normal operation. Here are the reasons for a noisy tensioner pulley: 1. Aging or damage to the internal bearings. In severe cases, the tensioner pulley may completely fail to function. 2. Damage to the tensioner pulley can cause timing belt misalignment, leading to ignition and valve timing disorders, engine shaking, difficulty starting, and even valve deformation upon starting. 3. If the generator belt tensioner pulley is damaged, the vehicle's generator may not work properly, and power steering may become ineffective. Below is additional information about the tensioner pulley: 1. The tensioner pulley is located on the engine's timing belt or timing chain, providing guidance and tension to both. 2. During the operation of the timing belt or timing chain, the camshaft drives the valves to open and close at the correct time, coordinating with the piston to complete the four processes: intake, compression, power, and exhaust.
