The PK belt is a type of drive belt that transmits power from the engine to various components within the vehicle, including the alternator, power steering pump, air conditioning compressor, and water pump. Unlike traditional V-belts, which are usually designed for one single purpose, the PK belt features a series of grooves along its length, allowing it to effectively grip multiple pulleys at once. This design not only improves efficiency but also saves space and weight in the engine compartment.

The designation 5PK essentially indicates that the belt has five ribs. Poly-V belts are a type of V-belt that features multiple longitudinal ribs or grooves, allowing for increased surface area contact with the pulleys. This design maximizes friction, enabling higher power transmission compared to traditional V-belts. The P in 5PK refers to the Poly-V design, which is characterized by its flat profile with grooves running along its length.
