Dayco 89052 Idler/Tensioner Pulley: Optimal Performance for Your Vehicle Review

Slightly smaller than OEM, doesn't seem to matter, works perfectly. 20,000 miles and then again. No parts, just a GM quirk.

Idler pulley received quickly. The bearing is good quality, the diameter was smaller than my original 05 Envoy 4.2L. I installed a pulley, it works quietly and the smaller diameter doesn't affect the belt tension.

Bought this spanner and another from someone else. Both were wrong! Also, you need the puck or it will move. Ordered and compared a tensioner assembly from Autozone. Your pulley is smaller and without a washer. So I will use it for everything!

These pulleys are supposed to match the original but are NOT. They don't work on the Hyundai 2.4 because the front end is too low and the mounting flange touches and fixes the surface. He doesn't turn around after pinning her. Look at YOURS and then THIS and you will see a matching problem.
