An accessory drive belt tensioner is a component in a vehicle's engine that maintains the proper tension on the serpentine belt, which drives various engine accessories like the alternator, power steering pump, and air conditioning compressor. It typically consists of a spring-loaded arm and a pulley, allowing it to automatically adjust and keep the belt taut as it stretches or wears over time. Proper tension ensures efficient operation of the accessories and prevents slippage or belt damage.
