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.

Over time, timing belts experience wear and degradation due to repetitive usage, exposure to high heat, and oil contamination. It is essential for vehicle owners to monitor for any signs of wear, which may include unusual sounds originating from the engine, such as grinding or whirring; visible cracks or fraying on the belt surface; or, in severe cases, complete breakage. A broken timing belt can lead to catastrophic engine failure. Knowing when to replace the belt is crucial—most manufacturers recommend replacement around every 60,000 to 100,000 miles, but this can vary significantly based on vehicle type and driving habits.
