I have a 2004 mountaineer that needs a belt change. I have found the pulley where I think the belt can be loosened and tightened. Problem is I can't figure out how to do it. Can I find something on the Web which provides details.

Thanks

 

The tensioner usually just swings back with the help of a 1/2 " drive breaker bar. There is even a square hole in the tensioner wheel itself tro accept the breaker bar. Just apply a swing with one hand and pull the belt loose with the other. But check youtube...they always have help there.
