If you do not have the belt that came off the way it is set up now without the A/C, the best way to determine the correct length is you have to get a piece of ribbon about a half inch wide and wind it around each pully making sure that you follow the correct groove side to back side of the belt. Remember that the tensioner will be fully extended. Once you get the length of the ribbon you then measure the length of the ribbon and subtract about 2 inches. (this depends on how many pullies and how many times is wraps around the accessories.) This is a trial and error method there is no exact way to find the length you are looking for that I know of. Once you get the length take that to your auto parts store and get that length and try it. If it is too long you can guess about how much too long it is by looking at it with the tensioner all the way retracted. Do the same if it is too short. A piece of ribbon gets you closer than string as it fits on top of the grooves.
I hope this helps. Let me know if there is anything else I can help you with or if you have any questions about this post. Thank you Brian
