What Is A Serpentine Belt

A serpentine belt is a type of drive belt used in an internal combustion engine to drive multiple devices such as an alternator, power steering pump, water pump, and air conditioning compressor. It is called a serpentine belt because it winds through various pulleys in a serpentine pattern. The belt is typically made of rubber and is reinforced with fiber cords to increase its strength and durability. It is designed to wear gradually and need to be replace periodically as part of regular car maintenance.
