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.

Unlike traditional V-belts, ribbed belts feature multiple grooves along their inner surface, allowing them to grip the pulleys more effectively. This design not only improves efficiency but also allows a single ribbed belt to replace multiple belts in a vehicle, simplifying the engine design and reducing weight.
