I installed my electric fan a couple weeks back along with my airaid intake and the e-fan has seemed to help quite a bit.

My first full tank of gas with these mods installed netted me 19mpg. I have NEVER seen better than 18 ever. I saw 18mpg one time sissy footin around on the way back from Houston. I got the 19mpg just driving normally around town, well there were a couple highway sprints at the Dallas meet which should of hurt my mpg but it didn't. I usually average between 15-17mpg so I was quite impressed.

I took it to the track one time since these mods and it seems to have helped. I only ran one time because the track prep was terrible but I compared the results to my best 1/4 slip ever and it shows that I was closing the gap I lost off the line.

Stat***Best***New**Difference
60':***2.283*2.853**.57
330':**6.972*7.918**.946
1/8:***9.971*11.595*1.624
mph:***69.83*68.19**1.64
1000':13.051*14.716*1.665
1/4:**15.654*17.333*1.679
mph:***86.81*86.57**.24

So you can see by the difference in nph that I was reeling my old time in. I went from 1.64mph behind at the 1/8 to only .24mph at the 1/4.

Great mod, definately recommended.

How are these fans being mounted? I have been warned NOT to use the ones that mount with straps through the core for offroading. Could those of you using them tell me how you're mounting them?

John, I'm running the flex-a-lite black magic and it is held on by metal brackets which hold it to the top and bottom of the radiator so the only thing that actually is in the fins is the temp probe.

Before I would get about 15-16mpg, the lowest I"ve gotten since was 16.8 but I've gotten 18 on two seperate tanks since then.

Truck seems alot smoother, not as much pedal needed to get going.

As far as the install goes, the worst part is getting to the wiring really, finding the HVAC and fuse wires was the worst part of that end. Another pain is getting off the old mechanical fan but its doable.

Hope this helps you out.

I agree on the pedal response. It seems to particularly help at low speed.

I'll post my install when I do it, with some pictures. I haven't checked my mileage yet. I usually get about what Coy was getting. Of course, my efan is not installed yet -- all I've done is remove my existing mechanical fan because of the siezed clutch.

On the 3.0, the fan clutch is reverse threaded onto the water pump. On the 4.0, it comes off the way normally threaded things do.

I used a "hybrid" approach to removing it. I used a chisel and hammer and tapped on the big nut at an angle to help loosen it, then a wrench to break it loose while squeezing tension on the belt to keep the pulley from turning. It came off pretty easy that way.

The shroud is no problem. Just two bolts.

I'm reusing my shroud, with a thick 1/4" silicon rubber sheet cut to fill the space between my 16" diameter fan, and the 20" diameter hole in the shroud. The efan will actually mount to the shroud itself. That way I'll get the full efficiency of the fan through the entire radiator.

I ordered a thermostatic controller with the little sensor that goes in the radiator fins. We'll see how that works. If I'm not satisfied, I may put a water sensing system in.

I'm thinking about getting a 6" efan and another thermostatic controller and putting it on my tranny cooler as an independent system.

Coy, thanks for starting this topic -- it helped push me to replace this fan with an efan when the clutch just happened to go bad about the time you brought this up! :)

Bryan, I was able to do it for about $100. The vendor I used has more. If you can, wait and see if mine seems okay quality wise. Of course, a long term test is in order. But it seems like a good deal for an adequate fan.

I paid about $100 for both the fan and controller.

What fan did you use? I was looking into the Flex-a-lite Extreme Black Magic.
What size? And is it controlled automatically?

This msg was editted by me cuz the questions kept pouring in..

lol! I posted here on it somewhere. Let me find it and you can look at the auction. It's a no-name 16" fan, 1920 cuft/min and a thermostatic controller. It came from an eBay seller with lots of sales and 100% feedback so we'll see. He also sells more expensive fans. The fan was $62.00 and the thermostatic kit $38.50 and shipping was free for both for the auctions I did.

Here's my original post:

Okay, spent $101.50 and got this 16" fan:

http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWN%3AIT


and:

http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWN%3AIT


What I'm going to try to do is mount that fan in the existing shroud, with some thick silicone rubber sheeting filling the 2" open space around it. Then I"ll get the air flowing through the entire radiator.

I'll post pics when I get it set up.

I believe approx 2000cfm of this system will be adequate if properly shrouded. I think many fans lose a lot of effective flow "talking to themselves" around the edge of where they are mounted.

I didn't have to pay any shipping. The first auction was confusing since it said that "buy it now" purchases had no shipping -- but it was ONLY a buy-it-now auction! I talked to the seller and ended up deducting the shipping. The thermostat kit ships free when you buy a fan, so I didn't have to pay on that either. Basically, I just went electric for the price of my deductible.

Coy how about some price and part numbers on your e-fan mod. Any pictures?

John, do u think the 16" fan will be enough for the 4.0L too? Is there anything that is not reversable? 100 bucks isn't bad at all. Are this flex-a-lite getting good reviews and lasting long?

Flex-a-lite, Spal, and all the major brands are probably pretty good. I have no idea how good the one I'm buying is! If you don't want to experiment, best spend more money, lol.

I think it would probably cool the 4.0 -- but it's just a hunch and you'd probably want to check with someone who has done it with a fan in this range. There are 16" fans out there with about 150% of the output of the one I just bought, up in the 3000 cfm range.

I'm one of the suckers that goes for the brand name. I know in my head that "off brand" and "generic" stuff can be just as good as the name brand...but trying to get my to spend money on that is tough. The price is good...but I wonder if 16" is enough for a 4.0....I'll need to research.

Thank you so much for your info John!

John, you are more than welcome, I'm glad to be of service. :D

Adrian, I have the Flex-a-lite black magic and it works very well. Its kinda loud when it blows though, I came out of the gas station thinking there was a dryer under my truck but hey, I guess thats what 2800cfm will get ya.

I'll try to get some pictures for you guys here soon. Keep in mind my install was for function over finesse so its not pretty but gets the job done.

I have the 150R

I got it for $170 shipped on ebay.

I think Robin said that Parr automotive or someone makes the exact same fan so you may be able to find it cheaper but I'm happy with mine.[/url]

Here you go Adrian. Sorry about the poor quality. I had to use my camera phone because my bro has his digital camera in Houston.

Great, thanks Coy. Does the fan come with that red shurd? I assume theres another bracket on the bottom of the radiator just like the top one?

Yes Adrian, there is a brack at the bottom just like the top. The shroud and fan are actually one assembly so you won't have to install them seperately. They come in Red, Blue, Black, and yellow I think.
