Cool Installing an electric fan in F-150

My F-150 needs a little more get-um-up. I have read that the fan on the F-150 can drain as much as 15 hp. I have a 94-95 GT fan sitting around in my basement. From what I have seen I will need to fabricate some brackets for the fan and install a fan controller. My questions are: 1. Does anyone recomend one controler over another? 2. Are there any tips to an install like this?

Thanks

Try Matt at O'Reilly's (Banditmwp) or you could order one from summit that would work - http://store.summitracing.com/partde...5&autoview=sku

I seriously doubt you'd gain 15 horsepower. What year/engine? Is it the OEM fan clutch?

In any event, since you've got the electric fan already, it wouldn't be a bad idea.

Don't use crimps. Solder/heat shrink all the connections. You also don't really need a controller. A switch, a relay and a fuse will be fine and much cheaper.

The reason I asked about the fan clutch is because aftermarket fan clutches may not work as well as the OEM. My old F150 sounded like a jet because the aftermarket clutch I got didn't disengage. If that's the case with your truck, you will certainly pickup some fuel mileage/power.

Bracket? I assumed you meant a bracket to mount the fan assembly on the radiator.

I do not really even know what a fan clutch is. What is it?

Yeah, to mount the fan

fan clutch is what the 'actual' fan mounts to. (the center section of the fan) If you have the fan off, look at the center of the fan, you will see a metal center. That is the clutch

Also, depending on your water pump & pulley, you may need to get shorter bolts. Once you remove the four and take the clutch/fan assembly off - when you thread them back in, they may be too long and bottom out into the housing.

http://en.wikipedia.org/wiki/Fan_clutch

As for the mounting brackets, there are a number of things you can do. You could just get some bar stock, and bend up some brackets. You just need to make sure the fan assembly is held tightly against the radiator, and that there is no interference. The assembly shouldn't allow too much air to leak out the sides.

I just made two big hook type things for the bottom mounts. The fan just sets on them, and they have a hook to keep the fan moving back. At the top I just made two little right angle brackets with holes. The angle pieces bolt to the top of the radiator (there is a little flange with holes) and I drilled a couple holes in the fan shroud.

Alternatively, there are these zip-tie like things out there. They are square with a long zip tie thing. You put it ziptie part through the radiator. Drill a whole in the shroud and then use a retaining clip to hold it snugly together. They seem to work just fine

I think you can get away with the "zip tie units", but I found that after time, they tend to stress the rows & fins which leads to leaks. If you have any kind of Macgyver or "A-team" skills, then try & fab something up.
