The “4PK” designation refers to the specific configuration of the belt itself. The 4 indicates that the belt has four ribs, while PK signifies that it is part of the multi-ribbed belt category, also known as serpentine belts. This type of belt is designed to drive multiple accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. The use of multiple ribs provides a greater surface area for friction, enabling the belt to efficiently transfer power from the engine crankshaft to the various components.
