You can probably changed it without pictures. You can take the serpentine belt off, and to do that you actually turn that tensioner that you want to replace, which releases the tension on the Belt. Once you have the belt off there is one bolt to take off the tensioner arm. It all comes off in one unit, and the new one will come already assembled, with a new bolt, ready to disc boat right in. There was a little pain that needs to line up to make sure you get it in the right position, other than that there's nothing to it.
