U don't, if anything you add an inch. If u measured without a tensioner, then the belt needs to be longer.

No I added it with the tensioner but with no tension on the tensioner , if I go longer the tensioner won't do anything

Route a piece of twine around your pullies in the exact same pattern as whatever your routing is (not sure if you've deleted anything). Then have a buddy grab the ratchet and go to full tension on the tensioner. Pull the twine tight, mark it and measure it.

There is a diagram floating around specific to SN95 5.0's the A/C and PS are in different locations.. I believe I've posted on here before, if not use google images or bing images, it'll pop up.

Only way to do it.

I got two different size belts on both my cars.

Both 88's. not too sure what the difference is cause I haven't looked to closely. I used a piece of string wrapped it around and measures with my tensioner in the middle of the safe marking. A buddy of mine actually somehow turned the tensioner around to lift up for tension. Not to sure how it worked.

The diagram I was referring to.

Not really sure what all these diagrams are going to accomplish or the conjecture... I already mentioned the best way for him to figure out EXACTLY what length he needs in about 5 minutes with no guesswork... This thing called Empiricism...

Apparently this forum should be called "ask Scotty" because apparently his opinion and know it all wisdom is all that matters. Everyone else's opinion and advice is merely discussion fodder for him to discredit. I think I'm finally done with this forum. Later!!

That was a little un needed..

The original poster obviously doesn't know what to do with these diagrams, so Scotty just gave him the easiest, most fool proof way to figure out. Simple..

Drama bombs! Good thing the diagrams he posted accounted for pulley sizes other than stock like underdrives... oh wait they don't...
