My sincere apologies for the delayed response.
I am personally going back to answer your unanswered questions.

I do not know if you still need this information, but I am going ahead and answering it anyway.

CLICK on the following LINK. It has the Belt Diagrams you will need.

The standard rule to removal the Serpentine Belt:
1. Find the Tensioner(s). (See Diagrams on Link)
2. Rotate/Move the Tensioner away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.
