Re: Junkyard Upgrade - Dual Electric Fans

Possibly the Taurus fan pulls a few less amps than the Mark VIII or Contour fans? I really regret that the Flexalite VSC didn't work for me. IMO, it has all the features a variable drive should have.

Road Test Fail

A quick update on the Contour Fan and TorqFlo controller on my '91 Foxbody...

The TorqFlo controller died after 400 miles. The controller stopped functioning, and the wires for the T-stat were actually beginning to come out of the T-stat tube.

I bought another TorqFlo just to get the vehicle running, but I'm looking into the Ron Francis controller which seems heavier duty. Wish me luck...

I used the newer version of the flexalite fan control unit. I have had it for about a year now. I have not had any problems yet. Knock on wood.

The second TorqFlo failed after just 160 miles. Something in the controller short circuited, causing the fuse and its holder to melt. Underhood heat and the current draw of the Contour fan are the likely reasons.

I just ordered a Ron Francis 70 amp wiring kit through Summit

Will post results when I can put some road miles on her.

Re: Junkyard Upgrade - Dual Electric Fans

FYI- I;ve been running the Flexalite Varible speed controller version 11, (version 11 has a modified temp.control knob, version 1 was easily turned past its stop, making it non-adjustable) for over 2 seasons with no issues whatsoever.
Running the Taurus single fan(wired to hi-speed only) on a 450hp-347.
62 Fairlane, minor trimming of the Taurus shroud was the only mod.required.

IMHO, the components of the Ron Francis kit are quality. The 70A relay and Maxi fuse are robust. Even the grade of the wires are a step above what one would normally expect. The downside, if there is one, is the requirement to tap the T-stat housing for 3/8" npt. That, and the lack of being adjustable.

The fan comes on at 172F (measured with an infrared thermometer) which is pretty much where I wanted it.

The kit is designed so simply that there are very few components that could fail. There are no electronics of unknown origin or questionable longevity. The Ron Francis kit is simple, and I like simple.

Only fifty miles of road testing, but honestly, I'd be surprised if it doesn't outlast the car. Coming from an electrical engineer. Just my 2 cents.

Hope this helps.

Re: Junkyard Upgrade - Dual Electric Fans

Will you guys ever learn STOP using these high price aftermarket fan controllers . Go to your local junk yard and get you a VOLVO 2 speed controller and as much wire harness as you can ( you will the plugs ) . You can wire it using a thermal switch or a manual over ride switch . The last 2 I bought were $6.50 each and if you want to buy new you can get one at NAPA for about $55.00 .

The Volvo part acts as the main relay. You still need an ignition relay, possibly an AC relay, fuse and fuse holder, thermal switch (as mentioned), wiring, and connectors. These parts will add to the cost, but the two-speed controller is really trick.

This is an interesting writeup:

Wiring 2 speed fan with volvo relay. - SyTy/SGT - Forums

Wished I had known about this when I was installing a Mark VIII fan on my F-150.

Looks like that would work well. And would be cheap to copy.

Re: Junkyard Upgrade - Dual Electric Fans

Maybe someone who is running the Volvo unit will do a "how to install/wire the Volvo fan controller" write up.
I alott of guys, who would certainly look at it as a cheap alternative, myself included, if the flexalite VSC ever cack's out on me.
