Does a Faulty Tensioner Pulley Affect Engine Power?

[CourtneyFitz]

Tensioner pulley damage affects engine power. Below are the relevant details: 1. Function: The tensioner's role is to guide and maintain tension on the engine's timing belt or timing chain, keeping it in the optimal tension state. It generally operates through either hydraulic or mechanical methods, both of which automatically adjust the tension of the timing belt and chain. 2. Wear Item: The tensioner pulley is a wear-prone component in automotive parts. Over time, belts tend to stretch; some tensioner pulleys can automatically adjust belt tension. Additionally, a tensioner pulley ensures smoother belt operation, reduces noise, and prevents slippage.
