More About Engine Drive Belt Parts

Drive belts transfer crankshaft power to various accessories, including the alternator, water pump, power steering pump, and air conditioning compressor. Replacement of drive belts, serpentine belts, and drive belt tensioners at recommended service intervals helps you avoid untimely breakdowns and expensive vehicle repairs.
