SPECIFICS:

FAQ - Answer 1Yes, pulley bearings meet or exceed original equipment and are designed for application specific speed and load requirements.
FAQ - Answer 2No, always use the pulley called out in the ACDelco Catalog for your application.
FAQ - Answer 3Yes, 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 - Answer 4Yes, a patented vibration damping system improves not only tensioner life but also belt and accessory life as well.
