What is av belt?

An av belt, also known as an auxiliary belt, serpentine belt, or drive belt, is a critical component of a vehicle's engine system. It is responsible for transferring power from the engine's crankshaft to various engine accessories such as the alternator, power steering pump, air conditioning compressor, and water pump.

The av belt is typically made of a durable, elastic material such as rubber and is reinforced with cords to provide strength and resistance to stretching. It features grooves or ribs on its surface that match the pulleys of the engine accessories, allowing for smooth and efficient power transmission.

Over time, the av belt can wear out due to constant use, exposure to heat and friction, and general wear and tear. Signs of a worn or damaged av belt include squealing or chirping noises, visible cracks or fraying, and problems with the functioning of engine accessories.

Regular inspection and maintenance of the av belt is important to ensure the proper functioning of the engine system. It is recommended to replace the belt if any signs of wear or damage are present to prevent potential breakdowns or failures while driving.
