....is there a way to remove both the smog pump AND the ac compressor, without having to use the eliminator kit?

I want my power steering..just not the other needless ola.

Viola! No AC!

Ok since you are the perfect candidate to experiment with this I have an idea.

On Jcassity's thread he discussed placing the tensioner on the belt that leaves the WP to the ALT.

It is very tight as is but if you place the tensioner on that part of the belt and run it as the the green model with the 77" I used it might work. You will probably have to alter the stops.

I am going to draw this up real quick

It looks like there will be a problem with the belt clearing the top of the tensioner pulley, BUT the pulley in the pic is not fully extended. I am sure there will need to be some ginding like Jcassity did only on the lower stop. I think you *might* clear the WP with about 2 inches of clearance.

Also another option would be a smaller tensioner pulley.

FordTruckFreak, if you could please try this for me I would really appreciate it.

You Have no AC on your pic and that makes a world of difference. Get the idler up over the other side of the belt,after you modify the tensioner so it has more CCW motion and it might work.

you will see where i explained what i did. 77 works perfect. Your pic has the belt on the wrong side of the idler. I have my belt routed as per the green diagram.

Stock fox Cougar brackets and as you can see the a/c is in place. A/c works fine so no reason to remove it.

What electric fan are you using?

So it sucks? I was just wondering since from what I remember you have a similar engine set up to me. I guess I'll stick with my stock fan and 5.0 Mustang Police Interceptor fan clutch for now.

Looking at that other thread, in Inne's pic, his PS bracket is moved up, that's exactly what I want to do...but is his the stock Tbird bracket, or a Mustang?

It sucks alot of air alright. But no matter what, the fan wasn't designed to fit the radiator and no matter what I did it still looked bad.

Looking at the routings; I noticed something. You can run the smog pump & A/C delete (purple) with the same routing as the A/C in place with no smog pump (blue).

You'll need a bigger belt though....

*EDIT* 76 inches works.....You could most likely get a 75.5" to work as well, but a 75" aint gonna happen.....
It actually has less tension, but is within limits and the belt has much more clearance.

I did this today with a 1985 LTD 5.0 HO, ex-police car. I just purchased this car for $400 on a street near my house.

I found a local guy that was selling the AC delete pulley (stock AC no longer worked) and when I put this on the stock belt was a hair too long. I thought if I was to buy a new belt I might as well by-pass the smog pump as well. I ended up with a 850K6 (they did not have a 845) and it seems to work great with the purple route.

Thanks for the info guys this will make it a lot easier to change out the plugs and work on the engine.

Now I need to find a fan shroud.

Hey now,, put up a couple pics without the air cleaner. Id like to see what the pn is on the injectors and also if you can tell us the color of them. I would be surprised if they were blue tops.

With a 351w block, march underdrive pulleys, and the route on the bottom I used a 86" belt

I think I used an 862k6. 86.2" long I used the smog delete belt routing with the purple belt in the above. It provided the best belt wrap on the most accessories.

I used the above purple routing and used a Napa belt 6k860, which is a overall length of 86.4 inches. I tried a shorter 6k854, but it was too short. I had a little smaller alternator pulley and the 862 would have been too long. Just adding to the thread. All other pulleys were stock.

This is great, but has anyone done this on a 3.8? (1988 specific)? I figured out my belt length, put it on, and then i realized I was running my water pump backwards!!!!! So now, I cannot figure out how to run the belt without causing it to run the opposite direction, and have to take the belt back and put the pump back on unless somebody knows the solution. Please help!!!! I'll put up pics when i get home

I haven't, try measuring the way you need with a rope, It will get you close. Start a new thread for yours. If it's running backwards, you missed something,
