engine accessory drive belt

The term 4PK refers to a specific type of fan belt characterized by having four ribs on its inner surface. The PK designation indicates the design style, which is often found in multi-rib belts used for engaging multiple accessory components powered by the engine, such as the alternator, power steering pump, water pump, and air conditioning compressor. The ribs help to ensure a firm grip on the pulleys, enabling efficient power transfer and minimized slippage.

Micro rib V belts, also known as ribbed belts or serpentine belts, feature multiple longitudinal ribs that run along the length of the belt. This design allows for a larger contact area with the pulley, which increases the friction and provides better grip compared to traditional flat belts. The micro ribbing not only maximizes the transmission of power but also reduces slippage, which is essential in applications where consistent performance is necessary.
