installing new serpentine belt

The operation of cogged belts is primarily based on the interlocking design of their teeth. When the belt is driven by a pulley, the teeth fit snugly into the grooves of the pulley, ensuring that there is minimal slippage. This characteristic offers a high degree of accuracy, making cogged belts especially suitable for applications where precise timing is crucial, such as in engine timing systems, where the belt must synchronize the crankshaft and camshaft rotations.

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.
