Serpentine Belt Size

[mf7lakes]

OK guys n gals -- don't beat me over asking this:

Is there a definitive way to order the correct size serpentine belt the first time around ??

Does Ford still make them ?

I have looked through several parts catalogs and there are multiple lengths shown all over the map.

Thanks in advance........and yes I did a search through old posts and never found a "hit the nail on the head" answer.............

Well it's not the one that AutoZone calls for. It's too short. It's ~111 inches and the only way to install it is over the vacuum pump pulley. The ambulance package belt is ~113 inches, that is my next try.....

Im running a 1120k6 on my 93. Seems to work very well

On my 1993 E350 7.3L IDI N/A,

I have used 112 and 113 inch belts without problems. The 112 needs the idler pulley fully lowered to get it on the last pulley, the alternator pulley. It had to be the alternator pulley.

It will stretch a fair amount over time.

O-Reilly's Auto Parts can get many different lengths if the clerk has a brain and knows how to use the computer.

Autozone Duralast 1110K6 is the one I used originally for my '93 F250 M code (NA) engine with A/C.

There was a trick with that^ I can't recall what had to go on last but it had too,in order to go on.Alternator? Vac pump? Don't recall.Whatever it was,it had to be last or forgetaboutit.

Since ditching the vac pump,I now run:
Duralast Belt #1080K6 (snug fit without vacuum pump there,but once on,tensioner isn't bottomed out and belt is perfect fit)

Real snug! The trick to get this one on without a vac pump,is to slide one rib at a time over the AC clutch.It's a ****** and takes a good 30 seconds of swearing lol.Then once on,there is just a bit of play in the tentioner.Not completely bottomed out and with it nice and snug,there's no slop in anything across the wide span.

All these numbers work but best check the tensioner for correct fit. All tensioners have a measurement on them for fit. Most have no idea of this. On my tensioner that has the shock absorber on it there is clearly a place showing the fit on the black plastic.Look at ebay for this.http://www.ebay.com/itm/New-Genuine...ash=item3607c97881:g:4PIAAOSwQM9UZnot&vxp=mtr
