three v 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.

The type of vehicle you own can also affect the price of timing belts. Certain makes and models may require specific belts that are designed for unique engine configurations. Luxury vehicles or models with complex engine designs typically incur higher timing belt costs. Moreover, vehicles that have non-interference engines—which allow some margin for slack in belt functioning—may have less expensive timing belts compared to interference engines, where the failure of the belt can lead to significant engine damage.
