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.

The steering belt, often referred to as the power steering belt, is an essential part of the power steering system. This belt connects the engine's power steering pump to the engine itself. The primary function of this belt is to transfer power from the engine to the pump, allowing for the proper functioning of the power steering system. While modern vehicles may employ electric steering systems that do not use belts, the majority of older and some newer models still rely on hydraulic power steering, making the steering belt an indispensable component.
