A/C belt broke again. Which pulley is idler? Which do is repack with grease? PIC A/C belt broke for the 3rd time. I bought a new belt and some wheel bearing grease yesterday. I'm going to try repacking the pulley? Which pulley should I remove? Should I try them all?
Which one in this diagram?

The bottom one is the tensioner, top is what I call the idler. I picked up a new tensioner for around 50, and a metal idler around 25 at local stores. I had an issue earlier this year when I removed the water pump and somehow got it installed a little lower. Had an interference problem with the bottom of the pump and idler pulley. Have you done any work before the belts started breaking?

It's on a 2000 Camaro SS. The belt/pulley squealed badly before the belt finally broke. It did the same thing last year. I know you're not supposed to do this, but when I spray wd40 on the pulleys, the squealing went away. I'm going to check them both out.

I busted the crap out of my knuckle, but I removed both the top idler and bottom tensioner. Both were dried out so I repacked them with a little grease and snapped the seals back on. WORKED LIKE A CHARM. No more squealing and I think it solved the problem of the breaking belts. Thanks everyone!!
