When discussing the timing belt, it is essential to acknowledge the differences between timing belts and timing chains. While both serve similar functions, timing chains tend to last longer than timing belts, often exceeding 100,000 miles without requiring replacement. Timing belts are quieter and lighter than chains, making them a popular choice for manufacturers prioritizing engine design efficiency. However, timing chains can withstand more stress and are generally considered more durable.

The timing belt is a rubber belt, often reinforced with fiberglass or other materials, that connects the crankshaft to the camshaft in an engine. Its primary function is to synchronize the rotation of the crankshaft and camshaft, ensuring that the engine’s valves open and close at the appropriate times during each cylinder's intake and exhaust strokes. This precise timing is crucial for maintaining the engine's efficiency and performance, as it helps prevent misfires, optimizing fuel combustion and power output.
