I'm running no smog, the Ford Racing A/c Eliminator, and an alternator bracket ( no tensioner ). I dont know what size belt I need so I only had a belt big enough for the water pump, alt, and crank. I need power steering! Ideas?!
Take a string or a even a tape measure and run it along the pullies just like the belt is going to go, and measure how long you get. Go to the parts store and buy 3 belts...one the size you measured, one an inch smaller and one an inch bigger. Take'em home and see which fits the best, then return the other 2.
Oh come on, you know it's never that easy! Besides, chance are you'll need a different size anyways and just get frustrated and feel like you were givin wrong info. Hell to be honest i don't even remember what size i'm running and the lettering has wore off the belt so once mine needs replaced, guess how i'm gonna find out?
(actually, i'm gonna cut the old belt and measure it and then do the 3 belts thing like i mentioned above)
