The fan belt, commonly referred to as the serpentine belt, is responsible for powering several accessories in your vehicle, including the alternator, power steering pump, water pump, and air conditioning compressor. Typically made of durable rubber, its design allows it to withstand high temperatures and flexible movements. The fan belt is an integral part of the engine system, helping to circulate coolant, which maintains the engine at optimal operating temperatures.

The designation 6PK refers to the design specifications of the fan belt. The 6 denotes the number of ribs or grooves on the belt, while PK signifies that it is a part of the PK series of belts, which are commonly used in automotive applications. The ribbed design is critical because it enhances the belt's grip, allowing it to transmit greater torque without slipping. This is particularly important in high-power applications where maintaining consistent tension and friction is essential for performance and reliability.
