poly v belt pulleys

The PK belt, also known as a serpentine belt or ribbed belt, is a key element of the engine's accessory drive system. It is named for its PK section profile, which features a series of ribs that permit better grip on pulleys. This design allows the belt to efficiently drive multiple components such as the alternator, power steering pump, water pump, and air conditioning compressor. The effective operation of these systems is crucial for the vehicle’s performance, safety, and comfort.

A V-ribbed belt pulley is a type of pulley specifically designed to work with V-ribbed belts, also known as serpentine belts. These belts feature multiple longitudinal ribs that run parallel to each other. The design allows for the efficient transfer of power from the engine to various accessories, including alternators, power steering pumps, and air conditioning compressors. The ribs fit snugly within the grooves of the pulley, providing a reliable grip that minimizes slippage and ensures optimal performance.
