Purchased this for a 2006 Taurus with a 3.0L SOHC engine. There is only one idler pulley but part listings show two different parts, which are different diameters. Mine was 90mm, which is about 3-1/2 inches. I believe the other was 76 mm, or about 3 inches in diameter.

Had to modify the dust cover (the big flat washer between the head of the bolt and the bearing)to maintain an OEM function. The bearing spins smoothly, but the whole assembly seems to have excessive side-to-side play. We'll see how long it last.

          Perfect match for 2002 Explorer idler pulley. Seems like a quality part - steel pulley, not cheap plastic. Quiet. No issues so far.

                This is not the correct width 90mm idler for 99-04 F-150/Lightning 8 rib belt applications. It will wear the belt quickly if used due to belt riding off edges of the pulley. Dayco 89048 should be listed for this application.

                        I'm happy to help, Tim! For your 1997 GMC K1500 SLE Z71 4x4 5.7L it will depend on what your vehicle has for an idler pulley currently. If it is grooved it must be replaced with grooved. Smooth must be replaced with smooth. From what I see the grooved pulley tends to be for the trucks without A/C. Based on your serpentine belts routing, either the smooth side of the belt or the grooved side of the belt will come into contact with the idler pulley and that will need to match.
