How do you change a serpentine belt on a 95 park ave Do you need to remove the upper engine mount?

I have a '96 Ultra and I've changed both belts. I had to remove the bottom screw of the upper engine mount to change both the Supercharger and Accessory belts. Take the right front tire off for easier access. Remove the bolt, then get a star socket and remove the screw. There is a metal piece held in by the screw. With the screw missing you can now pull the belts through. You'll have to route the belts in front of the pulley that is behind the mount.

I am a Do-It-Yourselfer. I've done this twice. And that's how I did it.

Also, make sure you don't waste your money on cheap belts. Pay a little extra for good belts so you won't have to do this much.
