ribbed drive belts

In addition to the timing belt itself, other components of the timing system—including the tensioner and idler pulleys—should also be inspected regularly. These parts play a key role in maintaining the proper tension of the timing belt. If they wear out or fail, it can cause the timing belt to slip or misalign, leading to similar issues as a belt failure. Therefore, replacing these components simultaneously with the timing belt can save time and money in the long run.

One notable feature of timing belts is their quiet operation. Because they are made from rubber and have a non-metallic composition, they generate less noise compared to their chain counterparts. However, timing belts do have a limited lifespan, typically ranging from 60,000 to 100,000 miles, after which they need to be replaced to avoid catastrophic engine failure. If a timing belt breaks, it can cause severe damage to the engine, especially in interference engines where the pistons and valves occupy the same space.
