The serpentine belt is typically driven by the crankshaft, which is connected to the engine. As the engine runs, the crankshaft spins, thus turning the serpentine belt. This rotation powers the connected components, allowing them to function efficiently. The belt's tension is crucial; if it is too loose, it can slip off the pulleys, leading to ineffective power delivery; if too tight, it can cause excessive wear on both the belt and the components it drives.

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.

3. Fabric-reinforced Materials Flat belts may also be constructed from fabric-reinforced materials, typically combining textiles with rubber or polyurethane layers. This reinforcement provides additional strength and flexibility while still allowing for a lightweight design. Fabrics like polyester or cotton are often used, and the choice of fabric can significantly affect the belt's performance characteristics, such as its ability to handle loads and resist wear.
