How do you put the serpentine belt on for the power steering pump and alternator on a 2004 Dodge Intrepid what needs to be loosened?

loosen the nut on the idler pulley. There is a bolt at 10:00 o'clock from the pulley.

Loosen this bolt until you can put the belt on then tighten the bolt till the belt is tight then tighten the nut on the idler pulley. Recheck the belt tension after a day or so..
