   HOW TO REPLACE IDLER ARM AN TENSIONER PULLEY ON A 1995 ... Serpentine belt replacement Buick Lesabre 1998 3.8L Oldsmobile, ...

Those belts have a tensioner on them. IF the belt is too big then the tensioner might not be retracted. It might be missing. There are idler pulleys too. If you have high miles on the this car, the pulley or the tensioner might be worn. The tensioner also has to be pulled back to have the belt put on.

You might just need a fan bellt or serpentine belt, get an empty spray bottle mix a small amount of
dish soap and water, spray on belt, then start your engine if the noise stops just replace your belt.,
if it does'nt it could be another pulley or the tensioner pulley, then i would suggest removing the belt
and spin each pulley to determine which one is making the noise. if it turns out to be the alternator, you
will have to replace the whole thing. they don't normally sell just the pulley, and even if you can get one
requires special equipment to pull it off, if needed just replace it and save yourself time and trouble.
plus parts normally come with some kind of warranty. good luck!

Sounds to me like an idler pulley bearing. If that is for sure where the sound is coming from. If thats the case then time to swap out the pulley.
