You guys that replace idlers and belts just because it hit 100,000. Where's your faith in GM?I haven't replaced any of that and I'm coming up on 200,000 miles. Been carrying the spare belt in the tool box now for over a year, maybe someday...
Little hint, take your cell phone and take a picure of your belt routing before it breaks and keep the picture in your phone. Oh and it don't hurt to photograph the belt part number that is on the belt you now have you know. So when you walk up to that parts counter looking for a new belt, the info will be right there with you.
