The lifespan of a rubber timing belt varies depending on several factors, including the make and model of the vehicle, driving conditions, and maintenance practices. On average, most rubber timing belts should be replaced every 60,000 to 100,000 miles. Neglecting to replace a worn or damaged timing belt can lead to severe engine damage. If a timing belt breaks, it can cause the camshaft and crankshaft to become out of sync, resulting in valve collision with pistons and extensive damage to the engine.

A fan belt adjuster, commonly referred to as a tensioner, is a device that maintains the proper tension on the fan belt. It ensures that the belt remains adequately tight to prevent slippage during operation.

If the fan belt is too loose, it can slip off the pulleys, leading to a complete failure of accessory operations, while a belt that is too tight can cause excessive wear on both the belt and the components it drives.
