Are you anywhere near the parts store? If so you CAN drive a very short distance without a belt...i drove about a mile on mine and it didn't over heat. Other than that your best bet is to probably just measure the belt path with either a tailor's measuring tape (the soft flexible kind) or run a string around the belt path all the way around untill it reaches the other end, then measure the string and take that measurement to the parts store, buy 2-3 belts in sizes around that measurement and then use the one that best fits and return the others.

when i had mine on my car, with a/c delete.. just to run the crank, water pump and the alternator, it was either a 60.5 or a 70.5... I really think it was a 60.5. The string method is really the best way to find out. the tensionor will eat up 2-3 inches if its too long.

When i do the string i pry the tensioner all the way down so i know the string isn't slacked and that helps to compensate for belt stretch.

The first time i did this, i bought a belt that fit fine when i put it on and a few days later it was loose and my tensioner was maxed out and i had to buy a new belt.


Also pay real close attention that you get the belt path right if you're using the FMS AC eliminator kit. There's 2 ways to run the belt that seems like it'll work but one way the belt will eventually rub itself.

i dont know the exact size but after taking the s/c off i needed a shorter belt and went through 2 differant sizes at auto zone b4 finding the one i needed laying around my own garage.. heres a pic i had to push the Alt; further away to make it work this summer im either taking the A/c out or buying the right belt

I have always used the masking tape method. Same as the string method mentioned above, but i started that when i heard that when using the string, it goes in the grooves of the pulleys and can be about 1/2" off of your measurement..

Yeah that's true....i'd say you're right the tape would probably be a closer measurement. I've even cut the old belt since it was getting trashed and was too long, and then measure the belt itself since it's already in the grooves.

thats a good idea too

I will say though, unless your car is a show queen or something, get a marker and write the belt size somewhere inconspicuous in your engine bay, that way the next time you need a short belt, you've got the info right there, because the print will wear off the belt.
