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.

The belt connects the crankshaft, which is responsible for converting linear motion from the pistons into rotational motion, to the camshaft, which controls the opening and closing of the engine's valves. During operation, as the crankshaft spins, the timing belt rotates, in turn spinning the camshaft. This precise timing means that as the pistons move down to draw in air and fuel, the camshaft opens the valves at exactly the right moment. If this synchronization is off, the engine may not operate efficiently, leading to performance issues or, in extreme cases, severe engine damage.
