Who's running an Electric Fan?

Once I do my v8 swap in the spring, I may go with an electric cooling fan. Anyone done this? Did you mount it in front of or behind the radiator? What do you use to control it? What year/model car is a good donor vechicle for an electric fan? What amp rating is your alternator?

 

I run an electric fan between the radiator and grill for my 283. I have it on a three way switch; automatic (it's a got a temp sending unit in the radiator), off, and on. Mine was a universal electric from the local A/P store, Hayden I think. Can't remember the diameter, can check when I get home. Standard GM alternator, 60 amp I think.

BTW - I'm still running the standard engine fan too.

 

I'm running one, I mounted mine behind as a puller, it depends on the amount of room you have, I runa Hayden I think.
Get the biggest one that will fit.
As for the controler, I just use a switch and relay. They sell auto kits witha temp sender that cuts on and off.

 

If you want a junkyard fan, a Taurus or Sable is a good choice.

If you go this route be sure to get the low profile motor. Looking at the pictures on these sites comparing to whats sitting on my garage floor - there is more than one type, and the one I got isn't low profile. Might have to take another shot at it - these fans do blow hard!!

 

I'm running a low profile 2400 CFM pusher between the grill and radiator. If anything it works too well.

 

Didn't I read here that the Taurus/Sable motors draw a lot more amps than the aftermarket ones do?

 

In my opinion it's not worth running the taurus sable stuff. A good perma-cool is under $100 brand new with the mounting hardware. Not sure why everyone is so hot on junkyard electrical parts.

 

Chuck, could you point me to where I could get a 2400 CFM pusher fan for under $100? Summit lists them closer to $200.

 

Part number PRM-19115 at summit racing is what I run. $99

 

I picked mine up at a flaps.

 

Cool - thanks. Don't know why I didn't see that when I searched.

 

I got a Flexalite 1800 CFM for $25 from a friend who pulled it off of his SBC. Its a pusher and is installed on the front of the radiator. I've got it toggled switched, no relay, on the dash. Works great for the V6.

This is the one I've got. It's in front of my radiator and I also have a 16" engine driven fan. Keeps my 283 nice and cool. Don't forget you'll also need a 3 row radiator. I had mine custom built by a local shop. We used Chevette radiator tanks with a custom width core.

 

I have a Chevy 383 ci V8 in my frame rails and Dan is right about the mount. I had a `68 Impala 3 core radiator in the Jeep when I got it, it would only run at 205* or higher. I went with a puller, "Spal" fan that was one of the more expensive high rated fans, with the ziptie mounting, well it vibrated loose, punching 4 holes in the core at 13,000ft. AAARGGG!!! Well, I got back to flat land, 5280 ft and went looking for a better way. I work on a couple NASCAR Stockcars and we use aluminum radiators, I went and found that with the airbox cut off the stock `62 grille, a 19" x 22" x 2" radiator fit up there nice. I run a 170* stat and it never over heats now, even without a shroud around a 17" steel fan. The radiator came from http://www.speedwaymotors.com Their Tru-cool radiator is only priced at $139.95 and you don't have to worry about using amps. click on the pix for the link.


Oh yea, don't use a flex fan with a V8 Jeep and a small radiator, been there fried that. A flex fan will flatten out at higher rpms, so if gassing it in 3rd gear 4low up a hill you are NOT cooling the Jeep. I've fought this cooling issue for 3 years before getting the radiator, so I've been around the block with this one.
here's a link to my posts using keyword radiator.

Because its cheap and it works.
I have a pile of fans in my shop that were claimed to work, none did.
After my LT-1 conversion I could not get the motor below 225*. Space was tight and any of the low profile units did not pull the cfm to cool the motor.
I ended up going with the 3 wire Taurus fan and a late model CJ grill. Had to cut the grill up a bit so that the radiator was right up to the slats and mounted the fan directly behind. The great thing is the fact that the Taurus fan is a drop in fit! I wired it per the pirate thread and it pulls air like mad. Now the motor runs constant at 185*-195*, no matter what the altitude or load.

I'm running a three row radiator from a 78 Chevy Monza with two 12" fans. Here is a picture. I'm also have a temperiture switch from a 82' Chevy Caviler. I haven't road tested it yet, but it turns on the fans at 210 degrees and then it shuts them off at 195.
