The End All, Be All FC3S Electric Fan?

Opinions are like........
Some FC's have a small electric pusher fan mounted in front of the AC condenser, just in case the mechanical fan isn't pulling enough air(cheap jab at the pro mech fan crowd). Obviously, with certain options and in certain conditions, the stock mechanical fan is lacking and needs help.

Alright, I'm not finding the wiring diagram for the single plug version of the mercury fan. For those that have wired it successfully, was the blue wire with the white or red the main low power line?

BDC, you are awesome I've got the fan wired up using the wiring diagram in the link. https://www.rx7club.com/showthread.p...t=electric+fan. Thank you arghx. I got it out of a Mercury for 40 bucks including a foot of harness. The valve cover for that horribly beat up van was painted lime green and the shroud was painted purple... So, I painted the blade and the motor cover a blue to sort of make it work. Haha! I'm still running the s4 alt, so I kicked the idle up to 1.4 rpms. She's running strong and steady with the corksport rad.

Good deal! Glad you guys got 'em goin'. We went thru the junkyards 'bout a year ago and grabbed four of 'em. Only one was bad. The others worked just fine and still work. May have to make another trip out there and look for some more.
They're a great fit around the FC radiators, huh?

My Daddy always said "If you want something done right, do it yourself." So since no one else had measured the current use of the Villiager fan, I decided to do it myself.
Background:
A couple of months ago I grew tired of the raucous single-speed Fan action of my Mighty Lincoln Mark VIII 18" fan. I switched back to my original 2-speed Taurus Fan. What a relief.
Except for a couple of nagging things. The Taurus fan was not the best fit on my Griffin Rad . The 16" Taurus fan just seemed, well, rather small. Then we all had the fun thread about freeway temperatures, leaving me with the desire for more open area in the fan, thus I felt renewed need for an 18" fan.
So I took the plunge Saturday at the local salvage and got my own End All Be All Fan.
Since my Griffin rad core is 19" x 19", the fit is purely custom. The Villager fan is +/-17.5" and has a much less aggressive fan blade than the Mark VIII. This is a good thing if you want some extra free air flow. And I do.
So a little time on the table saw, some aluminum angle crossed with the aviation snips, mixed with a little pop-rivet action yielded the perfect custom-fit fan. The fan gives me the wall-to-wall fan similar to the Mark VIII fan, adds lots of additional fan off airflow, but leaves me with the slick 2-speed action that I prefer.
Oh, yeah, the numbers. Slightly less than 10 amps on low speed, slightly less than 20 amps on high speed. I didn't take any pictures of the ammeter like I did when I measured the Taurus and the Mighty Lincoln Mark VIII fan but I measured it with the same gauge. The test yielded 5 amps less than the Taurus on both low and high speeds. 7 amps less than the Mighty Lincoln Mark VIII Fan's single embarrassingly aggressive speed. I suspect that the fan could be successfully used with a stock S5 alternator, I don't know about the S4.
How does it blow/suck compared to the Taurus and the Mark VIII? Less than either of those other fans. It is definitely powerful enough to do the trick. The large 18" fan blade has a noticeably longer spool up time compared to the Taurus and Lincoln fans. That would be expected since the motor is less powerful as evidenced by the lower amperage draw. The start up inrush amps are also lower, but last quite a bit longer.
Sorry for the crappy nightime Iphone pics.

I switched to this Villager fan last fall . At first I noticed very little change, but since spring I have been been unhappy with my temps. I have worried about the Griffin radiator, my use of Evans Coolant, my use of R152a etc. as reasons my temps were out of control. 220*-230* had become the norm. On hot days, I quit driving the car as the temps were wholly unacceptable.
This last week, my heater hose began leaking so I replaced it. While I was under the hood, I realized that the only thing changed was the fan. So I moved the high speed fan wire to the temperature controlled relay.
Bam! All weekend, temps never varied from 185*. Even 85 mph on the highway, whip off the interstate and idle=185*.
What's the take home on this?
1.) If you use this fan, don't bother with low speed unless you have a sophisticated control system that stages the speeds at increasing temps.
2.) The high speed on this fan likely pulls nearly the same or slightly more air than low speed on the Taurus fan, based on both my temperature experiences and the measured amperage draw.
3.) Low amperage draw fans may not have the static pressure capacity for extra thick radiator cores, like my 3" Griffin.
I am probably going to change to a dual-pass rad and a PWM controller with the Mighty Mark VIII or a Taurus fan when the Vert goes Turbo.

Time to revisit this thread. I have been running this fan for a little over one year. I have the two speed action set up as follows: low-speed on temperature at 195* off at 180* and high-speed runs only with the A/C compressor. When I was using the Taurus fan in this two speed mode, NO PROBLEMO on temps year round for 2 years. When I switched the Mighty Mark VIII, the temps never varied, but neither did the roaring fan sound.

I have ended my experiment with the Griffin Radiator. Nice, Big, Custom mounted and impressive, but I am convinced the coolant velocity is too low with the 1.3l 13b. It's made for a V* and that's where it belongs. Look for the FS thread.
I now have a single pass aluminum Koyo rad with a 2-speed Mighty MarkVII (Unicorn)cooling fan, Evans coolant. Running it on low for cool and high for A/C.
Done.

Just to contribute we used Aaron's efan guide and got what was described as a "87 88 90 93 FLEETWOOD RADIATOR FAN MOTOR" on ebay to go with the Godspeed aluminum rad controlled with a Flex-a-lite thermo switch. Even in our 100 degree Texas summer the temps are even and controlled with the super cold R134a converted a/c on. This is with distilled water, Prestone and no water-wetter; not the fancy Evan's.
The fan seems to fit the radiator quite nicely.

It seems from reading this thread that people have managed to use the factory thermoswitch and keep temps under 195*F with the fan on low. I'm looking for this from the two-connector fan.
But here is my main question. How is either fan wired? I don't plan to do a bunch of crazy things to this system. I want to do what I initially planned, or have low on always, hi on at 195* and off at 180* like some other members in this thread. For wiring the connectors, and I will read again when I return with a fan, Which wires cross to what? I will gladly admit that I am nowhere near the best at electrical stuff, but I really want to get this mod done while I have the whole front of my motor torn apart. 1/5 - 1/4 gauge sounds much better than 1/2!

Today I got a electric fan off a 92 dodge caravan I haven't used it on my car yet which is a built t2 with a BW s366 turbo but it mounted up nicely to the Koyo radiator I just had to trim the tabs off and about 2 inches off one of the sides.
I hope the fan is good enough I'm gonna have all the stock features like AC and power steering running.
