Belt squeak

Remove the belt, clean down all of the pulleys real good, especially the idler, and do the same to the belt. Make sure it doesn't have any cracks oneither side. I've got the same issue in my folks' Sable and I just bought some carb cleaner to try out on it.

there's going to be a tensioner arm with a nut in the center. I think there is a diagram on the underside of the hood or on the radiator cover that might show you which one it is. But, just use a socket set to either push it down or pull it up (cant remember which direction) and the belt will get loose enough to slide it off. Install is basically the same way; just start to route the lower pulleys then when you get to the last one or two put pressure back on the tens arm and finish routing the belt.

BTW...I just removed the belt from my folks sable and sprayed and scrubbed the carb cleaner on the idler and tensioner pulleys and the backside of the belt and after putting it back in its whisper quiet now. You can get the carb cleaner at autozone, advance auto, etc. I got the Gumout brand, but any carb cleaner should work.

just get some belt dressing in a spray can and spray on it while its spinning. that will help clean it off and condition your belt.

Belt dressing was just a band aid for me. The carb cleaner has been more effective thus far.
