I have a 1999 F150 with the 4.6 engine. I am putting in electric fan and would like some help. I got a great deal for a fan at a pick a part jungle. Its brand new, and for a 2007 silverado.


Now I just need a controler for it and idk what I should get. I want one thats reliable, and maybe has soft start feature. I got such a good deal on fan im not really concered with price.

Anybody done this on yr similar truck and could help? Possible some pics.

 

Two of the best.

FK-75 or FK-95:

You need to find specs on those fans to properly match the controller rating to the fan's current demands.

Here are the specs on 2010 F150 efans (RF-269) as an example:

( from this thread - https://www.f150online.com/forums/ot...ctric-fan.html )


Small fan

Diameter 14.5"
Hub diameter 5.5"
Current (no load) 24.83A
Current under load 26.24A
Starting current 69.64A
cfm (no load) 2797 cfm

Large fan

Diameter 15"
Hub diameter 5.75"
Current (no load) 27.64A
Current under load 36.35A
Starting current 69.64A
cfm (no load) 2964 cfm


Total

Current (no load ) 52.47
Current under load 62.59A
Starting current 139.3A
cfm (no load) 5761 cfm


And here's an install of a Mark VIII fan in a '99: https://www.f150online.com/forums/ar...150-4-2-a.html


Good luck.

So the fan is a Dorman 620-654. For some reason I can't find something to tell me the specs like cfm.

Yep - a little light on info elsewhere after a very brief search.

Need to wait until Dorman's site is back up I reckon.

So - this is not the OEM fan but an OEM replacement. Just so you know.

New on Summit they ar $180: http://www.summitracing.com/int/part...-654/overview/

You can get an RF-269 for less new.....

I'd wait on the controller until you can verify specs.

Hayden Imperial makes a damned good controller. I paid $40 for it about 7 years ago. It hasn't died on me since. A/C probe, adjustable pot, and two fused outputs. It does not have the soft start of some of the more high-dollar units, but its not that hard of a start, either.

 

140 amps is not that hard of a start? LMFAO !!!

And - Your Hayden controller would scream and die trying to cope with that, without a very large interposing relay.

We know you are running cheap non-name chinglish ebay fans - we get it - yer cheap Not everyone wishes to go that route. Some prefer OEM quality fans that actually move the rated air when loaded (not just loafing in free air, which is useless.). And a controller to match that offers less electrical system loading, can handle the enormous currents a genuinely high-performing fan will draw, and provides much better granular temperature control (which is why they are called constant-temperature controllers).

All we need is that feller Shifty85 whut runs manual cab switches to chime in " yall don't need no effin' controller!" to make this complete, lol.


NMiller: The Dorman site is back up - http://www.dormanproducts.com/itemde...SEName=620-654

Still no details (disturbing, that). They do indicate on the Technical Info tab, a tech support email addy - see if they know any more.

You NEED those specs or yer flying blind. No way would I run an unrated fan (and OE replacement does not always ensure OE quality). But it's not my truck. If you ever overheat, you'll know why


Oh, BTW, yer welcome

Thanks MGDfan for all the help. I sent an email to their technical support asking for the specs. Ill update ya when I get it.

 

DC is a one man operation from everything I have read and getting in touch with him is like winning the Lottery. Expect to wait.

 

Thankee! Lookin' forward to it.

Y'know - all the times I've dealt with him, response was very timely indeed. He even provided free support for a controller well out of warranty that I didn't even buy from him. Exemplary.

Well the guy, Chris Lehn replied very quickly. This is what he said.

"These fans are about 16.4” OD. The left fan draws 26 amps the right draws 20 amps (the report does not call out start up spikes) The CFM rating is about 3000 per fan."

Sounds like they're pretty powerful.

 

Hi.


Well, that's a start. Draw sounds a wee bit low for the stated CFM (compared to the Motorcraft unit). Which probably means the CFM is slightly overstated.

I reckon there's no chance fer a datasheet like Spal provides for example: http://www.spalautomotive.com/eng/pr...01-AP90_LL-79S

http://www.spalautomotive.com/public..._catalogue.pdf

To be safe, I'd use the inrush numbers for the Motorcraft unit in the absence of published data. So the controllers I mentioned will work.

Should work out to be a nice system. Ensure the shroud is sealed around the rad as best you can - this hugely affects efficiency.

Good luck!

I ended up buying the DCC FK-75. I'm guessing it'll be the right fit for my fan.

 

I'm very happy w/ the DCC FK-50P I installed a couple years ago. It's worked flawlessly since installation.

Consider the fan speed indicator light ... I find it useful.

 

So i ordered the fan controler from DC about a month ago, and I recieved a purchase email, but nothing else. It should have shipped to me by now, but I don't even have a shippment email. I sent an email into support, but no reply. Any seggustions of what I should do?

 

What is the benefits of replacing the mechanical fan with these e-fans?
