Yeah, the raw aluminum radiator looks sweet. What was the part number for that?

Do you have it wired up for low and high speed?

I had also went with the Lincoln mark Vlll fan in my 77.
i drove it home that night for about 12 of the 20 miles and the truck died. tried to start it and the battery was dead. came to find out that the stock alternator is only 65 amps. Lights on were drawing about 10. the fan was good for about 30. the fan was drawing faster then my alternator could replenish the battery.
I went back to my mechanical and bought a new clutch fan at the same time. it stays at a rock steady 192 summer or winter AC on or off.
Plus a mechanical is better for a truck that hauls or tows. if you look at any heavy duty truck you'll never see an electric fan. its always a mechanical one. there much better at cooling.

Well everything is working great! as far as the alternator I'm running a 100amp chevy one wire alt. I'm Going to do a 3g conversion next weekend. That will solve any amp draw problem . The main reason for the electric fan was for snow plowing

How do you figure their better at cooling? They put a mechanical fan on there because their cheaper to manufacture, not because they cool better.

akforceten, how did you wire it up to kick the low speed off when the high speed kicks on?

I know you didn't ask me this question but this is how mine is wired to cut off power to the low when the high is energized. The power diverts from 87a to 87 on relay #2.

Very nice! I took one from a T bird too. It is basically a mk8 fan, same blades, housing. Ford used many different fans with the same blades, etc, just diff. motors. That configuration came in several diff. vehicles. It is a great fan.

If I were you, I would have minimum a 75 amp relay for the high sp. The two speeds should never hot simultaneously, or you'll fry your fan. Internet lore says that fan moves about 2500--2800 cfm on low, and about 4500 cfm on high. One write up I read the guy said on high it would pull a cat through the radiator, ha ha.

THE GUY WITH THE INLINE 6: There just isn't room for that fan in your engine bay. It is close to 5.5" thick. You might want to look at a Ford Contour fan. I have a write up for it in this forum under Taurus fan install. It is a dual fan system that moves 3400 cfm. The big draw is that it is only 3.3" thick. I also have an article about it coming out in True Blue Trucks magazine, $70 fan upgrade.

Good luck.

I am using a toggle switch that is on-off-on. The switch is wired to a ignition on so I leave the switch on low an use the key. If I need it on high I just flip the switch to high , but I haven't needed to use high. This was the simplest an cost effective for me a auto thermostat switch was to expensive for me . cost was around $72 that I don't have . I spent the money on the aluminum radiator

Thank you F-250 restorer I haven't had to use the high side of the fan ,but they are on separate circuits . I do know that it sucks a lot of air it will hold a piece of paper to the radiator on low . The relays are 40 amps each an they are working good .

Dude, on high that fan will draw way over 40 amps! It will fry your relay on high. You need an 80 amp one. I don't want to rain on your parade, but I also hope you have a good high amp alternator, because when that thing kicks into high, it's a whole different world, and I hope you're prepared for it ... with 10 ga. wire, etc.

It is a terrific fan, the best, and that rad. of yours is super too. I hope you get many miles out of them.

Good luck.
