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.

The auto drive belt, often referred to as the serpentine belt or accessory drive belt, plays a crucial role in the performance of modern vehicles. Despite its relatively small size, this essential component is responsible for transferring power from the engine's crankshaft to various engine accessories, such as the alternator, power steering pump, water pump, air conditioning compressor, and more. Understanding its function, maintenance, and the implications of a worn-out drive belt is important for any vehicle owner.

V-belt drives feature a belt with a trapezoidal cross-section that fits snugly into the grooves of the pulleys. This design significantly increases the friction between the belt and the pulleys, reducing the chances of slippage and allowing for the transmission of higher power loads. The compactness of V-belts enables them to fit into tighter spaces, making them ideal for applications where space is a constraint.
