The Stovebolt Site Forums The Shop Area The Electrical Bay Electric fan installation question

Hi all, I'm installing an electric fan and have a question. It was my understanding that the fan should be mounted as low as possible for maximum cooling effect. I will have to mount mine high, above the water pump, because the water pump shaft hits the electric fan. Will this be okay for cooling? Note, this is not a stock engine.

Thanks, Don

Heat RISES, bro' ... the HIGHER you mount the fan, the more cooling you're gonna get.

The reason I put an electric fan in my truck was that my mechanical fan was sitting too low and not performing well enough.

If you're using a 16-inch fan, I suggest you use Two Relays -- See Here

I also believe in using a Fusible Link instead of a circuit breaker (and definitely NOT a fuse).

Thanks Joe and Alan for your comments. After I posted my question I got to thinking about it and figured I had it wrong in my mind. The hottest part of the radiator would be the top and that's where the fan should be mounted. Alan, I have been to your website many times and read all about your electric fan installation and the need for relays. I tried for 8 hours (yes, 8 hours)yesterday to call Mark at M.A.D. Electrical. I finally got through at 5:45 PM PST and talked to him about my needs. I ordered 2 relay kits for the fan and at the same time the alternator kit. Mark is very helpful and a nice person to talk to, but he sure is hard to get a hold of. Thanks again, Don

Hey, Don

I'm glad you finally got to talk to Mark -- he's hard to get hold of, but it sure is worth it when you do, eh?

That alternator kit is great -- be sure to put the diode on the ignition wire -- what a difference THAT made for me!!

Are you running an AD? Mount it on the street side of the radiator in a pusher configuration. It's more efficient that way, and you can't see it. It fits pretty well on that side.

I agree with TooMany2Count ... I've always heard that a puller is much more effective.

I installed my electric fan yesterday in a "puller" configuration. As soon as I get my relays from MAD I'll wire it up. I would like to install a switch so that the fan can be turned off for highway speeds. I've always heard that an electric fan is more of a hindrance than a help when you're traveling fast enough to get good air flow through the radiator. Any comments? Thanks, Don

painless wiring has a switch that attaches by a bolt on the side of the radiator that is temperture sensitive which would automaticly turn the fan on and off as needed. works like the new cars. no drilling needed to install attaches to an the radiator mounting bolt. ron
