Do you have a serpentine belt tool?

In the center of the belt tensioner pulley there is a bolt that will have a 15mm head. Use the correct addaptor to fit this bolt. Then turn the tool as if you where going to try to tighten the bolt. This will take the pressure off of the belt so you can slide it off of a pulley. Then you can let go of the belt tensioner and install the new belt.
