I realize it is very tight. They are terrible to work on. Have you tried to release pressure from the tensioner? That is the only way it can be installed.
When I say belt tensioner, are you familiar with what I'm referring to? Please let me know. I'm trying. LOL Also, you will likely need a ratchet or wrench with a long handle to reach the tensioner. Look at the pic I attached. Not having it in front of me, I can't remember which is the tensioner. However, I circled two pulleys. One is movable. You need to take a wrench and place it on the bolt I circled and when turning it, the pulley will move. Move it the furthest you can to the directions in which the belt will be loosest.
Let me know if that helps.
