A serpentine belt is a long, winding belt that encircles various pulleys located on the engine's front end. Unlike older vehicles that employed multiple belts for each accessory, modern vehicles typically utilize a single serpentine belt. This design simplifies installation, reduces weight, and improves engine efficiency. The serpentine belt is made from high-quality rubber and reinforced with cords to withstand extreme temperature variations and mechanical stress.

A belt and pulley system consists of a loop of flexible material—the belt—wrapped around a series of pulleys. The pulleys are connected to different components of a machine. When one pulley rotates, the belt transmits this rotational motion to other pulleys, which can drive different machines or parts of a machine. The speed of the driven pulley (output) in relation to the driving pulley (input) can be adjusted based on the size and configuration of the pulleys.
