v belt for automobile

The serpentine belt is a single, continuous belt that drives multiple peripheral devices in an engine, such as the alternator, power steering pump, water pump, and air conditioning compressor. This streamlined design replaces multiple belts, reducing weight, space, and the likelihood of failure due to wear and tear. However, as mechanical systems and engine designs become more complex, the demand for adaptability in these belts grows—leading to the development of adjustable serpentine belts.

PK belts are a type of serpentine belt used primarily for driving multiple accessories in vehicles. They are characterized by their unique design that features several grooves running along the length of the belt. This design enhances their grip and reduces slippage, making them a preferable choice for many modern engines. The ‘P’ in PK indicates the belt’s profile, which is designed to improve contact with the pulley, while the ‘K’ signifies that it is intended for high-performance applications.
