A serpentine belt is a long, winding belt that encircles various pulleys located on the engine's front end. Unlike older vehicles that employed multiple belts for each accessory, modern vehicles typically utilize a single serpentine belt. This design simplifies installation, reduces weight, and improves engine efficiency. The serpentine belt is made from high-quality rubber and reinforced with cords to withstand extreme temperature variations and mechanical stress.

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.
