A serpentine belt is a single, continuous belt that connects multiple engine components, including the alternator, power steering pump, water pump, and air conditioning compressor. The term serpentine refers to the belt's long, winding path around several pulleys, which makes it a crucial component for transmitting power. Unlike older vehicles that often utilized multiple belts for various systems, modern cars predominantly rely on the serpentine belt for a more streamlined design.

Poly V-belts, also known as ribbed belts or multi-rib belts, feature multiple ribs along their length, which increases the surface area in contact with the pulley. This design allows for higher torque transmission compared to traditional V-belts, making them ideal for compact applications where space is limited. Poly V-belts excel in environments demanding high-speed operations and have become a staple in automotive engines, household appliances, and industrial machinery.
