The DAYCO APV2762 tensioner pulley is a crucial component for ensuring the proper functioning of your serpentine or V-belt system. It works by applying consistent pressure to the belt, preventing slippage and ensuring that all accessories, such as the alternator, power steering pump, and air conditioning compressor, receive the correct amount of power.
