The timing belt idler pulley (also known as the timing belt idler) is a critical component of the engine timing system. Its main function is to guide and tension the timing belt, ensuring the engine valves (intake/exhaust) open and close at the correct times, thereby maintaining normal engine operation. If the idler pulley is damaged (e.g., metal fatigue, wear), it may lead to: Timing belt slack or breakage, engine vibration, abnormal power output, malfunction indicator light illumination, increased fuel consumption, and in severe cases, potential valve damage or engine failure. It is recommended to inspect the idler pulley condition every 60,000 to 80,000 kilometers.
