Taurus Cooling Fan Install

El, that sure looks real sweet, sorta like it was made to be there

I'm waiting with baited breath for the road test and 20 minute @ 100deg outside temp idling marathon results. Thanks for all the pioneering.

I see Dave's 2 hi-amp relays are rated for 40 amps continuous with a 60 amp peak load. I'm still half way tempted to build my own relay pack with 60 amps continuous and a 75 amp peak rated relays. I'd also use number 8, vice number 10 as Dave did. Ya just can't have too big a wire.....still mulling that one over.

It fits very well, though I am going to trim the edge off of the shroud from what would be the left side of the pic above so it looks more symmetrical. I haven't had much experience wiring relays so I went with Dave's Hollister setup. After looking at how they are wired, its a no-brainer and I'll be building my own from now on.

As you know, the motor on this thing is massive and much more powerful than a SPAL or Zirgo 16" fan. I am very excited to get it going.

Very similar to the Mark VIII fan, except the M8 is 18". The M8 fan fit my car beautifully. If I am not mistaken they use the same motor.
I like the aluminum surround treatment above...very clean and professional.

Actually, its just temp mounted using my 4 existing bolts and some thin 1" aluminum straps to keep it immobile. If it works as I planned, I will redo that top aluminum piece to fold over and come down to the top edge of the shroud, then do the same on the bottom. Right now I have about 1" top and bottom with core showing.

I think you are correct about the Mk VIII fan. Can you post up a pic of yours?

Thanks.

here is a picture of a 1997 ford thunderbird 2 speed setting electric fan I installed in my 428 c.i. - 400 HP cobra. On a 95 degree day, I can let the cobra idle for hours and the engine does not go above 180 degrees.

It looks like the T-Bird uses the same fan as the Lincoln MK VIII, 18" fan.

Cobraman428;
Did you plumb for both speeds? I just use the hi, run directly to a toggle switch. I would have run to a t-stat, but use the 'off' to warm the car up when it's cold outside. That doesn't happen much now...104 in the shade today in N Texas

I wired the fan on the high setting only and to a toggle switch with a relay. It is not tied into an automatic thermostat but might if I ever get around to it. I just keep an eye on the temp guage when sitting in traffic and bump the switch on if i see it creeping up. The 18" fan works awesome. I had to do some trimming on the shroud with a sabre saw but looks sweet !! The fan blades are only about 3/4" from the radiator fins. It had to be this tight because otherwise it would interfere with the rack & pinion steering.
I had the idea of using this fan from a wrecked 97 T-bird because the V-8 Ford T-bird would always sit in traffic with air conditioning on and never overheat??? I thought damm, why not try it on the cobra ! The results were very surprising and cost nothing.

TBird LX uses the same motor as an RX7 and it looks very much like a MarkVIII and has the same 18" blade. I use this one in my truck and it works great. The TBird SC is not the same, but may work just as well.

The Mark VIII motor is only in a Mark VIII fan. The Taurus/Sable and Lincoln Continental share a motor on the RF125 fan but its a smaller fan than the Mark VIII. The Mark VIII is an RF123 with a bigger motor.

Very in-ter-es-ting! (Remember Laugh In?)
I used the M8 fan because I had one in my garage from a car long departed. Was cleaning out the place and thought hmmmmm when I found it. All I know for sure is that it is strong. When it's on I have a very good draft under the car, much more so than with the Spal I had. I also use 2 'pusher' oe type fans in the front (home built) and I can run very well, even in ridiculous heat like we have now. Nice to know the lady luck smiled on me for a change!

Let me jump in here,,, The Beuler relays are 60 amp constant load on the high speed side and and 40 amp constant load on the low speed side. Hence the 40/60 Single Pole Dual Throw designation. The peak spike load is 150 amps but when you use the 180 temp switch the fan motor is rolling when you hit high speed so the spike of 100 amps is greatly reduced. If you buy one and it doesn't perform send it back within 30 days and I'll give you a refund.

Sorry Thor, don't "hammer" me for that one ...

I stand corrected. In the HVAC industry sometimes relays are rated continous and peak, which is not the same as in-rush (spike). The "ratio" of your 40/60 amp rating fit that mold. That being said, it would be a no-brainer to use your setup, not worth the effort and parts to build my own ... I still don't like the #10 wire though. I know, I know ....... it's adequate for the load and length of run.

Hey Gang,
My engine is 540 inches and have a 30"x17" alum. rad from Be Cool. I was already very close to getting the car to live on the 180* T-stat but could still get caught once in a while so wanted a little more. I installed the Lincoln Mark 8 fan on my Cobray C3.

This fan is a real winner !!! Just got back from a 300 plus mile week-end trip that included a parade. The ambient temp was 89 degrees with a little humidity for fun. The
4th of July parade took 54 min. to cover about 4 miles with the first 1/2 hour going toward getting in line and stagging. The car never got over 205 degrees but that was after over a 1/2 hour at idle.

The install was very clean and easy. I wired up a controller per the schematic with a few of my own twists. I used 2 adjustable temp switches, 3@ 40 amp relays and a few feet of #8AWG feed wire. The low speed turns on at 155 degrees with high fan kicking in if temp reaches 185* in the block. I also shrouded air flow from the fans up and toward the engine rather than down or under the car.

I did use a parade only trick that (Bob B) told me about to reduce under hood temps. Roll up a towel and set it on the air cleaner to hold the hood open a few inches so air flows out. The hood just rested on the soft towel so no harm no foul and did not look bad from the sidelines. The Lincoln Fan kicks a$$

This is good news. If Armando will ever send back my *&^%$ oil pan maybe I'll get a chance to test mine before winter when it drops back to 80*F.

Thought those of you using the Taurus or T-Bird fans would be happy to hear you can buy replacement motors if your high mileage unit fails or one speed goes out. see the link below at proliance.com. You will see there are about 3 manufacturers that list a replacement motor. Contact them to see how you can get one near you.
