belt idler pulley source

[girl mark]

Hey guys,

My 6.5 van has an squealing noise that I think is coming from the idler pulley up there in the serpentine belt. I don't have the manual for this engine yet and I'm trying to order the part online before I go tearing it apart. A few friends have assured me that it's a common failure point on those vehicles. Anyone know what the name of the thingamajig is and do it have a part number? Is there a good online aftermarket parts place you recommend- I'm new to GMC's...

thanks,
Mark

If its a idler pulley, it is avalible through the aftermarket. Its either a Gates or a Goodyear branded item. If you have a pic post it so I can Id it closer.
