Welcome, Going to move your post to the Ram truck section. I did send a message.

 

If the tensioner is frozen, Cut the belt. If i remember right there is a 13mm or 1/2 bolt head in the center of the tensioner. It could even be a 15mm or 9/16 bolt head. On the back side there is a pin to line up the tensioner.
