It's not really all that big. Get a piece of string and run it around the grooves where you want to go, then tie a knot in it. Take that string to a parts place and get a new belt to match the size of the circle you made with the string. First, check to see if your water pump pulley and your alternator pulley line up so you can use one belt. If not, then you will need to go with two, and use two different grooves.

yeah looks like they don't line up - so i'll go with two



thanks for the help!

if the grooves dont line up you might need some sort of a spacer...and remember to leave slack in the string when you tie it off to account for the extra thickness of the belt as it will not sit as deep in the groove as the string.

well the center groove on the main pulley lines up with the alternator, and the rear lines up w/ the water pump. I don't think I could get away with running a single belt to both...

I was afraid of that. Not sure how you will tighten the belt from the water pump if it is not the same belt as the one used on the alternator, since the alternator has the adustable bolt and the water pump doesn't. If this is the case, then you may need to get a tension arm with a pulleym or do as Shifty suggests and get a spacer. Ask the guys at the parts place what you need to make it work.

there are different offsets for the fan pulley depending if the car had ps or not. I cant be sure from the photo, but your fan pulley looks like the deep one. THere is a shallow one that you should be able to get one from a wrecking yard pretty easily so you just run the alt and water pump from the same belt and use the alternator to tension the belt. IMO that would be a lot easier than adding non standard tensioners. Also, the belt size should then be standard Ford.

I found this water pump pulley for a 302 - you think it would work?

And i've found a few water pump pulleys for cars with A/C - I wonder if they would line up. Hard to tell w/o having it in my hands...

You could replace the water pump and alternator pulleys with a single groove setup, since that's basically what you're down to. March Performance is one place that can help you out. Otherwise, you'll be spending money on pulleys that may or may not work.

You could also add a spacer between the WP flange inside the WP pulley to move the pulley out a little to line up with the alternator. This will add some additional stess to the water pump shaft bearings, however, so only do this as a bandage and not as a permanent solution.

I wonder if I should just throw the PS pump back in there and have it spin the water pump but not have the PS pump hooked up to anything - is that even possible (run dry)?
