I have a 1992 Dodge W250 Pickup. It has 102,000 miles on it and has broken the serpentine belt. The engine has air conditioning unit. I am trying to connect a new belt, same type as the one that broke however I cannot get the belt over the altenator (too tight). The tension pully is in (forward) as far as it will go. What can I do? I can get it over the altenator if I release the altenator from the mount but when the belt is on the altenator cannot be returned to its location.
