The designation 4PK refers to a specific type of poly-v, or serpentine belt, which consists of four ribs. The 'P' stands for pulley while the 'K' represents the 'K' profile of the belt's ribs. This belt is designed to drive multiple accessories in an automobile’s engine bay, such as the alternator, power steering pump, air conditioning compressor, and water pump. The ribs increase the surface area in contact with the pulleys, allowing for better grip and decreased slippage. This design not only ensures better performance but also enhances the longevity of the belt.
