What causes an idler pulley to stop spinning?
The same kind of visible wear is likely to be seen on the belt as well. It is thanks to ball bearings that the idler pulley rotates smoothly on its shaft. When there is a problem with these bearings, the pulley could stop rotating altogether or continue rotating but with rough resistance in every spin. This is a frozen pulley.
Why is my idler pulley on my GTP not working?
A few days ago the serpentine or “accessory” belt in my 2001 Pontiac Grand Prix GTP tore itself apart after some spirited driving. While replacing the Serpentine Belt and the Supercharger Belt, I noticed that a tensioner pulley and an idler pulley didn’t spin easily due to their bearings being worn out.
What kind of pulleys do I need for a Grand Prix idler?
The parts you may need to complete this procedure include the following: Dayco 89007 (Tensioner & Idler), Dayco 89051 3″ Ribbed Pulley, Dorman 419-602 (Supercharger), ACDelco 38009 (Supercharger), Gates 38009 (Supercharger), and the ACDelco 38006 (Idler Pulley).
What’s the difference between a smooth and a ribbed idler pulley?
Remember that smooth pulleys get the smooth side of the belt and ribbed pulleys get the ribbed side of the belt. Route the supercharger belt over or around the 3″ smooth tensioner pulley, the 3″ ribbed idler pulley, and the 3.5″ smooth idler pulley.

When to replace the idler and tensioner pulleys?
Pictures illustrated instructions for replacing the idler and tensioner pulleys in a 1997-2003 GM Pontiac Grand Prix GTP.
Remember that smooth pulleys get the smooth side of the belt and ribbed pulleys get the ribbed side of the belt. Route the supercharger belt over or around the 3″ smooth tensioner pulley, the 3″ ribbed idler pulley, and the 3.5″ smooth idler pulley.
