electric fan
 

im looking at putting an electric fan on my truck. will a single 16 inch with 2100cfm be enough to cool it?

Re: electric fan
 

I think so

Re: electric fan
 

If your radiator, waterpump,ect is in good shape, you should do ok with that on a mild build. I would try to set up a shroud to mount the fan , rather than through the core like the manufacturer suggests tho.....thats tough on radiators. I run a pair of 14" fans on a home made shroud (1350 cfm ea),with Painless controls & they do fine keeping my 383 cool.......:crazy: L

Re: electric fan
 

I run a flex-a-lite 295 series on both of my trucks. It's a dual fan variable speed setup that works great.

Nice lookin setup, & a clean install:) ......what does she pull (amps), & push on the cfm?

Re: electric fan
 

It pulls 16-28 amps. The CFM is variable from 2760-4600. Here is a link to the rest of the specs. http://www.flex-a-lite.com/auto/html...-electric.html

Re: electric fan
 

thanks, i was planning on making a shroud for it and maybe running a dual fan setup to get about 3200cfm. is the Painless fan control the best one?

Re: electric fan
 

The flex-a-lite unit comes with it's own controler. It has an adjustment for the temp the fan will come on. It also makes the fans run when the A/C kicks on. It also has provisions for a kill switch(used primarily for water crossings in the 4x4 crowd). You can see my controler mounted to the core support.

Asa's set-up is a perfect fit, very minimal bracket fab needed, there are also
some available through the board vendor WES, his are a direct bolt in, but it
does not crank out as many cfm's as the one Asa is running, Getting mine in
the near future, If you've seen Asa's rigs you will notice he runs these fans
in everything he owns, I saw them in person at P.F., and I think they could
suck a golf ball through a garden hose, or a cat through a dryer hose :lol:

Re: electric fan
 

I have a single 16" that is pulling about 2800cfm's and its doing alright. I have one of Wes's shrouds.

Re: electric fan
 

I was thinking of a single fan too. Mounting to the original shroud so it looks somewhat stock. Anyone have any write ups on this? What was used, how to set it up? All the kits Ive seen are dual fans that remove the shroud.

thanks!

Re: electric fan
 

I have a metal shroud that we made to fit the rad. then I cut 2 13" holes and mounted the fans and relays to the shroud from a 89 IROC that I'm parting out. the fans are about 12" across. Don't have the truck running yet, but hope to find out if they do the job shortly.

Re: electric fan
 

Farside, I used the original shroud with a 16 inch flex-a-lite, works great... got a couple pix if you're interested... all you do is drill a couple holes in the top and bottom of the stock shroud and bolt it in, then mount the shroud like normal, run your wiring and you're all set...

the fan comes in its own shroud, and the whole thing bolts into the stock shroud... only thing is you need to make sure the rubber gasket on the flex-a-lite shroud fits tight to the radiator core before drilling mounting holes in the stock shroud, so it only pulls air thru the core.

Re: electric fan
 

I run an electric fan in my stock shroud on my 77 k5 blazer and plan on doing same in my 69. Easy, just need to use a fan that will fit from inside at any point...meaning you it
touches the shroud so you can secure.
If you look at my 77 engine, you can't see the electric, just the stock shroud.
I'll post a pic if i can find it. The fan I used was from a mid 90's t-bird(super) and
it is two speed.

Not the greatest ange, but provides some view of the stock look

Re: electric fan
 

Cool! Id love to see more pics and info! I think I should do this while the weather is crappy. (started raining, need "garage" projects :)

Thanks guys!

Re: electric fan
 

Hey See Ten
What is the depth of the fans? I only have about 3.5 inches and the flex-a-lite website says that I need 4 inches to run the 295 model setup. Just trying to see if there was some fudge factor in there. Also is that the mounting bracket that comes with the 295 or did you fab that up yourself? Thanks for any help

Re: electric fan
 

I just went outside with a tape and a flashlight and 4" seems to be dead on. We fabbed up the top bracket, but it is pretty simple to build if you have access to some flat stock and a shear. We sheared the stock then welded the two small pieces of angle iron to it. I am sure that there are other ways to go about doing it but this let us bolt it in the factory shroud location. We used some of the universal (fit nothing) brackets that came with the fans to build some bottom brackets. They aren't pretty but they are functional. Oh by the way you can also see in this pic the 108 amp alternator we installed. It's an 84 Corvette item that bolts right on to the factory brackets. We just had to open up the adjustment slot of the top bracket for a larger bolt. I think it was about $89 at Auto Zone and has plenty of amperage to move the fans, run the A/C, lights, wipers and whatever else.
