Fan belts are critical for powering various components within a vehicle. They are responsible for transferring power from the engine to essential accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. A well-functioning fan belt is essential not only for ensuring that these accessories work properly but also for maintaining the engine's overall health. If a fan belt fails, it can lead to serious issues, such as the overheating of the engine or a sudden loss of electrical power, which can be both dangerous and costly.

The “4PK” designation refers to the specific configuration of the belt itself. The 4 indicates that the belt has four ribs, while PK signifies that it is part of the multi-ribbed belt category, also known as serpentine belts.

The use of multiple ribs provides a greater surface area for friction, enabling the belt to efficiently transfer power from the engine crankshaft to the various components.
