v ribbed belt

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.

Engine belts are rubberized components designed to transfer power from the engine to various accessories. The serpentine belt, for instance, drives multiple peripherals—such as the alternator, air conditioning compressor, power steering pump, and sometimes even the water pump. The timing belt, on the other hand, synchronizes the crankshaft and camshaft, ensuring that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes.

While non-interference engines have their advantages, they are not without limitations. Generally, these engines may not achieve the high-performance output that comes with interference designs. Manufacturers often use interference designs to harness the mechanical advantages of closely timed piston and valve movements, which can lead to greater efficiency and power. Consequently, many high-performance vehicles feature interference engines, leaving non-interference models commonly appearing in economy and compact vehicles.
