This idler pulley is a quality part and the price was very good through Amazon
Direct OEM replacement for my 2008 Yukon Denali. I replaced tensioner pulley along with this idler pulley at the same time as replacing the serpentine and A/C belts, all original at 126K miles. This idler pulley is a quality part and the price was very good through Amazon; however, my only gripe is the wrong size indicated in the listing: 5.2 x 5.2 x 1.5 inches (WRONG)... ironically though, ACDelco lists this size everywhere else, too. It's the same as my original pulley, a little over 3.5 in diameter. See photos that accompany my review. Notice a slight difference in appearance from old to new, as well as the photo in the listing. It's the same part though, just updated. Installation was easy with 15mm socket on 3/8 ratchet. After removing the tension from the serpentine belt and slipping it off the pulley, just loosen/remove the pulley by ratcheting the center bolt and reversing the procedure with the new one. Torque to 30 ft lbs and you're all set to reinstall the belt. Note: An old "working" pulley will spin more freely than the new one. That's because bearings are wearing out in the old one, thus it's more "loose." Bottom line: great part, great price, somewhat confusing listing with the wrong dimensions provided by ACDelco. Go with whether Amazon states it's a fit for your vehicle.
