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.

A timing belt set refers not only to the timing belt itself but also includes related components such as the timing belt tensioner, idler pulleys, and sometimes the water pump. Collectively, these parts work together to synchronize the rotation of the crankshaft and camshaft(s), allowing for precise timing of the engine’s intake and exhaust valves. When properly aligned and functioning, this set helps prevent engine misfires, loss of power, and catastrophic engine failure.
