Fan belts are elongated loops made from reinforced rubber and are designed to transfer power from the engine’s crankshaft to numerous accessories, including the alternator, water pump, power steering pump, and air conditioning compressor. Their primary function is to ensure that these components operate efficiently, contributing significantly to the overall performance of the vehicle or machinery. Over time, fan belts can wear down due to constant friction, exposure to heat, and environmental factors, necessitating regular inspection and replacement.
