When a car engine belt breaks, abnormal noises may occur during startup, the vehicle may experience power loss or slow acceleration, or ignition may become erratic, potentially leading to engine failure. Below is relevant information about engine belts: 1. Classification: Engine belts are divided into timing belts and water pump belts. Timing mechanisms use either belts or chains, with chains being maintenance-free and lasting the vehicle's entire lifespan. As rubber components, belts age over time and typically require replacement between 50,000 to 120,000 kilometers. 2. Causes of breakage: The belt tensioner pulley bearing may seize, causing belt strain; difficulty in crankshaft rotation can lead to timing misalignment, oil seal leakage may cause oil contamination of the belt, reducing its lifespan.
