An interference engine is a type of internal combustion engine in which the pistons and the valves share the same space within the cylinder at certain points in the engine cycle. This design allows for greater efficiency and better performance at higher RPMs but also introduces significant risks if the timing belt—the component responsible for synchronizing the rotation of the crankshaft and camshaft—fails. Understanding the implications of timing belt integrity in interference engines is crucial for vehicle maintenance and engine longevity.

The function of the power steering pump drive belt is relatively straightforward but critically important. As the engine runs, the crankshaft spins, turning the drive belt. The belt then transfers this rotational force to the power steering pump, enabling it to perform its function of pressurizing the hydraulic fluid. The most common type of drive belt used in modern vehicles is the serpentine belt. This single, continuous belt may also drive other accessories such as the alternator, air conditioning compressor, and water pump. In older vehicles, separate V-belts were used, but today’s serpentine systems have largely replaced them due to their efficiency and ease of maintenance.
