I know there are lots of threads about removing, deleting, taking off, or otherwise getting rid of one's smog or air pump. Well, for the 5.8, aka
351W, with air conditioning, with the single tensioner and serpentine belt setup, the part numbers that I have found are below:

Kelly Springfield 915K6
Goodyear 915K6
Durkee-Atwood 915K6
Dayco 915K6
Gates K060915
ArmorMark K060915
NAPA NBH25060915
NAPA PBH4060915

The application that you can use for your average bonehead parts guy to be able to find it is:

2000 Mercury Grand Marquis 4.6L V8

And yes, it's 91.5" long - 2 inches shorter than the factory belt. Hope this helps someone.

I dont have all of those numbers but I know when mine ceased
I took off the pulley and used a belt from an explorer to bypass the thing.

I don't know that this is certain, because I haven't personally tried it on a 302 aka 5.0. However, my sources are telling me it would be an 84.5" belt. Sooo....the part numbers would be like above, but with 845 in them instead of 915. For example, Gates K060845 or Dayco 845K6.

The application to search for these would be 1989 Ford Mustang 5.0 without air conditioning.

If anyone tries these numbers, please let us know whether or not they worked out.

Great idea for a thread..

What about a 5.8, smog pump deleted with a sag power steering pump swap. The pully on the sag is larger than the original one on the Bronco, but I doubt it's a two inch difference..

You've got me on that one. I used the saginaw pump with the ford bracket and pulley on it. If you figure it out, post it up!

This is a good thread, These are the ones for a 94 351 correct? Having the idler pulley doesnt affect this at all does it? I ask because I had thought that the setup with the idler was added in like 1992 but I am probably wrong.

It's for an engine with one tensioner with an idler pulley on the end of it. I believe there was a later setup that had two of them. This won't work for them.

I'll post a photo of the setup if I can find one tonight.

Yea my truck has an idler pulley and the belt tensioner with a pulley on the end of it.
Then these parts won't work. And I think maybe you'll have an issue with getting the water pump to spin the right direction, too. I remember reading something about that.

If you get it figured out, post your solution (and part numbers, etc) here so we can all learn!

Are you guys rerouting the belt for more traction on the water pump pully?
Mine looks just like your blue diagram, but because it's a 5.8, it's a 91.5" belt. So, I guess I am getting more traction on that pulley.

Some people try running it like the green is only without hiting the smog pump. This puts the belt verry close to touching itself at the tensioner and only touches 1/4 of the water pump pully.

I think the only solution is to buy the pulley that Ford Racing makes to go there.
That's an expensive solution, though. There has to be an easier/cheaper way!

Sorry to bump an old thread, but I'm running the 91.5" belt. I was wondering if anyone has found theirs to be too long still. My tensioner is just outside of the marks and I think it's causing a squeek that came back after I took out my air pump. I'm not sure how much more to take out of the belt to get it to tension right. Would an inch be too much? I'll have to experiment to find the right size otherwise.

I always buy mine by the size (i.e. how many inches long they are). All belts(?) have a secret number on them somewhere that tells you just how long they are. And I know most manufacturers make them in 1/2" increments. I'd try a 91" first Moz---then maybe a 90 1/2"-er..............

I'm running a Continental belt 90.5in total length. I actually have the upper hose tied back against the distributor because the tensioner was so high up that it would rub the upper hose. But since the tensioner is that far up theres more tension on the belt and i haven't had a noise yet.

Alright thanks guys. Sounds to me like 90.5 is just a bit too short, I'll be trying out that 90" 91" one!

I am no math genius but I am pretty sure 90 is shorter than 90.5:toothless

Bleh, typo. :banghead

Edit: Got a 91" belt and it fits perfectly, the pointer on the tensioner was right in the middle of the range area.
