if you can find the room, the best thread size for temp switch options is M22x1.5
niehoff p#ts81821 is a promosing part number for that thread size with 2 speed operation, first on at 189° second on at 198°

 

Whoa! $53.00 at Checker Auto for that particular sensor!

 

I think it was $30 here

 

Check this out it has all the info you need I did this to both my 76 f350 460ci and my 90 mustang 5.0 and it is the cats ***!!! it works great
FORDMUSCLE webmagazine: Junkyard Electric Fan

 

the windstar fits the trucks better and is dual fans rather then a single like the taurus
I bought a few of those goofy controllers but ended up going with the simplicity of a normal fan switch
I would never attach a cooling fan to the core of the rad, well I wouldnt put anything through the core like that but to each their own

 

I have flexalite dual 12" fans pulling and a perma cool coller/10"fan combo in front for the auto trans on a hot day you can see the temp gauge drop when they come on they work but I finally have a alt. that can keep up with them I went with a 3rd gen alt. I have one of those fans from a 3.8 tarus for my 5.0 mustang but have not hooked it up yet. I use painless relays to run them, if the sender goes out you can ground the wire to make them run and I can't stand those nylon ties they give you to mount with they just wreck your rad.

 

That looks like a nice option. Hmmm, how can we get a M22x1.5 thread though...?

 

if you buy a blingy aluminum rad it is easy to get that glued into the cold tank
maybe a rad guy could brase a fitting into a brass rad, dunno never worked with that metal
kinda why I went with single speed and 1/4 npt switch to run mine
when I add a second sender for 2 speed operation it will be in the hot water passages of the block

 

I had bought basket case Bronco a month or so ago and we took it apart to sell the stuff I didn't need or want and to get myself a 205 transfer case and drive shafts cheap to change up my 203 transfer case.

Well when we went to pick up the Bronco the guy had some other stuff for it one of the things was a clutch fan, now I didn't put much thought into it about this clutch fan until someone posted the write up about the electric fan versus the clutch fan versus the solid fan.

Well it's still a little on the cold side here in Ontario Canada and I don't have the time to wirer up an electric fan at the moment so I thought I have a free clutch fan and it can't take more than 1/2 hour to change it.

Well what an incredible difference it makes, the truck runs smoother and quieter a lot quieter and seems to have a real boost in power.

I took my wife out to the Wally Mart about 10 miles down the highway, she says what did you do to the truck, I say why do you ask?

She says it's way quieter and seems to drive a lot nicer, i said smoother she says yes that's it it drives way smoother and quieter.

I said I put a clutch fan on the engine she says what a difference.


I will be going electric for sure in the future but my god the clutch fan was way more than I expected.

Thanks again for opening my eyes.

Ok, I got my fan mounted to the radiator. It's not complete yet, but close enough to give everyone an idea of how it fits.

I think that an electric fan (shroud) needs to be "sealed" to the radiator to work the best, that way it can suck the air through the radiator instead of from around the edges of the fan. It is sealed real well on 3 sides, but the driver side still needs something to fill the small gap. A 1"x2" piece of angle will work nicely for this. I need to take the fan back out anyway, so I'll finish it then.

The passenger side is mounted with a 1"x4" piece of angle made from 12 gauge steel and bent 90*.

I rigged my relays to the battery to try it out and it seems like it should work real well.

Here's some pics...

 

Angle iron on an electrical fan & a radiator? WAY OVERKILL.

P.S. I'd worry about it conducting heat...

I am the King of Overkill

My Dad also gave me some crap for having so many bolts in it, too.

Put one on my daily driver. Love it. If you get one from an early 90's Taurus or even better is a Mark 8 fan. Either one of these have about 2000-2400 CFM and are excellent if you want to do it cheap. I also went with a Heavy Duty 4 core radiator though to help keep 'er cool. Like I said, it's a daily driver and it does wonderfully here in Oklahoma. Good luck.

 

I just got my new 460 running in my 77 F250. I installed a Milodon high flow water pump and hi flow thermostat, and am using the stock fan for now without a shroud. Even with a cam, intake and 10.5:1 compression, the engine temp sits right at 180 all the time. I am considering a Flex A Lite fan in the future.

 

You might want to put a shroud on that sucker before summer. My friends bronco always ran hot in summer till he put one on.
