A serpentine belt, also known as a multi-ribbed belt, is a single, continuous belt that drives multiple accessories on an engine, such as the alternator, power steering pump, air conditioning compressor, and water pump. Serpentine belts are designed to be more efficient and durable than traditional V-belts, and they can last up to 100,000 miles.
It is important to check your serpentine belt regularly for signs of wear or damage. A worn or damaged belt can slip, which can lead to overheating, power loss, and even engine failure. You can check your serpentine belt by visually inspecting it for cracks, glazing, or fraying. You can also check the tension of the belt by using a belt tension gauge.
