Review on ACDelco 36299 Professional Pulley Retainer by Sirious Cavalli

Perfect replacement for 2004 Silverado 5.3L pickup. Installation was quick, dramatic and easy. Fixed general sounds on these trucks. For best results, replace as many pulleys (idler, air conditioner idler) as possible at one time with new belts. This saves a lot of time during disassembly, since the tensioner can be replaced in about 10 minutes. I also check the part numbers against the ACDelco Parts Guide available online. This has been reliable proof of all my GM auto parts purchases.
