Thanks for posting that! I've been looking for the belt routing schematic for some time now. I recently bought a 87' mustang and the previous owner deleted the smog pump and the A/C. If you saw how the belt is being ran now you would laugh. The belt runs on both sides of the tensioner. I don't know how he did it, but when I looked at it I knew something didn't look right. Now I have something to go off of. Thanks again.

Is there a kit to remove the a/c, p/s ,and using smog idler pulley? It don't seem that you can?

Wont the stock vs. the no smog routing cause reverse water pump rotation? Never mind I got it now, just looks funny in the pic.

What size belt would I need if I went with that bottom right pic? The no smog and no ac. Looks like the belt is on the opposite side of the tensioner? How's that work?

Click to expand...

how does the belt go under the tensioner without hitting the water pump?

Here are my schematics for the SN95 5.0 (belt lengths assume stock pulleys):

Just put a ribbed Idler pulley on mine. Will test and take pix tomorrow. Looks like the alignment is a little off from the ribbed idler, not sure of how to fix that short of machining something.

think theres some pictures missing from this thread now, I have a 92 5.0 engine with the smog deleted and the ford racing ac delete bracket that relocates the PS pump to old AC position. think I was using a 73 inch belt, I have a new alternator with a 1.8 inch pulley on it now,should i use a 72.5 or 72 incher? wonder if they make em that size

If the 73" belt is loose go for a 72", or string it and measure.

You would use the RED belt routing in the very first pic (a couple down from original post)

As for belt lenght....FAR too many variations in what pulleys everyone is using. Stock, aftermarket, mixed and matched alternators, etc.

Best way to find a belt lenght is to get a peice of string, wrap it around the pullies in the appropriate pattern and measure it. I'd buy a few belt sizes and go from there. Settle on one on the "tight" side of the tensioner range as the belt will stretch slightly.

You can take an old belt that is longer, route it, Gorilla tape it over itself and go to the parts store. If they do not have the belt measuring tool (or give you a dumb look when you say you need one this size), go elsewhere or ask for the old guy behind the counter.
