What is a Timing Belt in a Car?

[DiHailey]

The timing belt is a crucial component of an engine's valve train system. Here are the specific details: 1. Function: It drives the engine's valve mechanism, connecting the timing pulley on the engine cylinder head at the top and the crankshaft timing pulley at the bottom. This ensures the engine's intake and exhaust valves open or close at the correct time, allowing the engine cylinders to properly intake and exhaust air. 2. History: Timing belts first appeared in the 1960s and were used in most 4-cylinder vehicles, with increasing application in V6 engines. Initially used in overhead cam engines, timing belts are more prone to wear compared to traditional timing chains.
