FAQ - A1Yes, pulley bearings meet or exceed original equipment and are designed for application specific speed and load requirements.
FAQ - A2No, always use the pulley called out in the ACDelco Catalog for your application.
FAQ - A3Yes, when your idler pulley or belt tensioner breaks, the belt no longer powers key systems within your vehicle. For example, the belt provides power to the alternator, power steering and water pump, so you may notice lights on your vehicle flickering due to the drain on your alternator, eventually leading to complete power loss, or your power steering no longer operating, or the temperature gauge reading increasing dramatically.
FAQ - A4Yes, a patented vibration damping system improves not only tensioner life but also belt and accessory life as well.

FAQ - Q2Are these pulleys interchangeable?
