squeeking noise from pullies

I have a 96 buick lesabre limited with ba 3800 v6 it has a squeek from the pullies. I have replaced the idler pully but still squeeks. think it might be the power steering pump. thank for any help

could be any of the pullys, pull off your belt, and twist them by hand, and listen for squeaks

Have you cleaned the belt? The belt gets a glaze to them over time and it can cause squeaks. Also remove the belt take a wire brush to all the pulleys and clean them. Over time the belt transfers some rubber to the pulleys whihc would help to make noises.

found the squeek it was the water pump and the belt tensioner
thanks
