Default electric fans.

04 screw, 5.4l, 2wd. Whos running a quality electric fan kit? On my o6 2wd 4.6l i bought the $500 flex a lite kit and it was a huge improvment. I had a level kit, 35's on 18's 456 gears and edge programmer and got an impressive 18-19 mpg on a laughlin trip(according to the edge) and definitely noticed power difference. Im trying to get my 04 truck with this 5.4, lvl kit, 35's on 20's closer to that, but being older and more money wise its hard to fork 5-600 on electric fans, expecially just dropping 800 on the edge and gears. haha. Anyone know of something quality that may be a cheaper route, or should i stick with the proven flex a lite?? Inputs would be appreciated.

A long, long time ago, I did a write up on buying a controller, and a Mark VII or VIII e-fan from a Taurus or Lincoln. The boneyards are full of them. It is a two speed fan, and a good used one can be had for under 50 bucks. Don't be afraid to buy used, as the one I bought a few years ago was in my 2005, then went into a 2000 Ranger, and is now currently in my 2007; used and still blowing low and high speed.

You'll pay more for a decent 2 speed controll then the fan itself; don't cheap out on the controller, and don't hard wire it directly to the battery!!! The good controllers will have two relays (one for the low speed for when the AC is on, and one for the high speed when the engine temp sensor that is adjustable on the good controllers). Beware! There are cheap controllers out there.

Total cost invested was $165.00. This setup is now on its third truck! I kept the old fan/electric clutch, so when I traded that truck for each new (used) one, this e-fan setup got installed into it.

And if you're worried about a used electric motor from a junk yard, don't. Mine is over 4 years old now, and still spinning. You can buy a replacement electric motor for them; just go to your parts store and ask for an electric fan motor for a Taurus; they are made by Siemens.

One good one is from Delta Current Control, the other is from Ron Francis (AR99 - $134.21 on Summit). Both have the dual relays, both have "staert up" amp protection. I prefer (and have) the Rom Francis unit, as it came complete with the heavy duty guage wiring, the wiring itself was labled, and is a breeze to install.

As to the e-fan, I cut the fans outer shroud off to have just its "ring" and installed it with spacers or brackets within the stock shroud. The picture shows two brackets, but I added a third at the bottom center also. Also, make sure the efan sits within the fan shroud enough to clear the center pulley nut once the stock clutch/fan is removed.

Here's a picture to descibe this:

If you go Bucko's route, make sure you are getting a 2-speed mark VIII fan.
Some are single speed, depending on the year. Those two speed fans are not plentiful in S.E. Wisconsin as I only found single speed.

I went with the 2010 Motorcraft dual fan's and the D.C.C. controller Bucko mentioned. Great thread from Blown Ford on the dual fan setup. Bucko has the most cost effective and functional setup.

I shopped, and didn't find a "kit" I liked.

Happy Wrenching!

I remember your wrote up. I def want to look into going this down the line. Is your truck a 5.4? If so I have a 4.6 can I still use your write up with all the sane parts you used?

I would assume you could as long as that e fan fits in your stock shroud, even if not, trim the shroud to fit and make brackets, but im almost positive its the same on both motors. I dont think ford would have wasted money and r&d for two differwnt fan shrouds for the same vehicle with practically the same motor

Yesterday I posted that not all Mark VIII fans are 2 speed. I believe you can tell by the connector on the fan motor. If you go this route, cut off some of the pig tail going to it. I think there are also replacement motors for the Mark fans but you shouldn't need one. Lots of threads on this. I have the 4.6L also and with the a/c on there is plenty of cooling. Remember the shop of the shroud helps funnel air to the fan.
Here ya go for the fan.

Skip the relay part and go bucko's way if you want to do the Taurus fan route.
Search for Blow Ford fan write up too.

Awesome, cant wait to get some free time to find a fan and get it all hooked up. Just got the edge converted to gryphon and this mod will compliment it nicely. I looked around for the blow ford write up, didnt see anything, can you maybe post a link to help me get there? Thanks!
