Whats the belt size and routing to bypass the air pump on a 91 Bronco 302 4wd with AC.

Thanks

 

Just take a flexible tape measure and run it around all the pullies and then go to a local parts store and tell them the length of the belt you need.

I don't remember what number my belt is but mine is all most to short. Besure you leave a little room for the idler pully to take up some slack
