Icon5 E-Fan and mileage. Chime in please.

I am thinking about spending some of the money I am saving for tranny upgrades for the Mustang, and buying an e-fan for the Ranger. The reason I am considering this is more for mileage reasons than for power. Now mind you I get an average of 21mpg with my Ranger (50/50 driving) and have gotten as high as 24mpg. That is really good I know, but with the price of fuel being what it is and is going to become, I want to see if the e-fan is worth it to eek out another couple of mpg. Plus I don't want to go off the 93 oct tune to save a few bucks if I don't have to.

I'd like a 50/50 average a couple of mpg higher if possible.

Also, while you are chiming in on the mpg benefits of the e-fan kit, tell me how well it is cooling for you and how durable it is.

Thanks.

I think I've gained about 1 more mpg, it isn't much, but better than nothing.

It cools pretty good, however I've had problems with the fan controllers busting on me. Its to the point where I wired up a switch directly to the relay for the fan, and I just watch my temp gauge more often.

I have the flex-a-lite S-bade and thier VSC controller that was left over from my old MCSS.

IMO it's not worth the money from a milage only standpoint. Unless your mech fan is in lock up a good part of the time.. you won't see much improvement. Less than 1mpg at best I'd guess.

Some side benfiets though.. smoother running, quicker starts, longer waterpump bearing life, less noise. And to some small measure mpg.

My last three tanks of 87octane have been over 20finally. I to am looking for every little tweak I can.

Thanks for the info. I am sure it will help and Jusnes kit is priced right. I guess I am more worried about it holding up. I do not want it to fail on me this summer.

Keep the truck moving faster than 20mph and even in the summer heat you'll be fine.

Once you get it hooked up you'll be supprised at how little it actually runs. That is except for when the ac is on.

For what it's worth..

I ignored the temp readings on the controller. What I did was measure head/coolant temps (autotap) and adjusted the controller to come on at 214-215F It'll run for a minute or so and the temps will come down to 205-ish.

It's not been to warm here yet. But even in the low 80s I gotta sit still in traffic for 3-4 minutes before it'll kick on. Warmer than that and I have the AC on.. which makes the fan run anyway.

Pretty much have it setup the same way on the Lightning.

They both don't run much at all.

I have the Jusnes kit and have never had any problems. However, I have not seen much of an improvement in mileage.

The best part of the efan is cold AC when sitting in the drive threw for long periods of time.

When i had the efan on... I got 20 mpg on the highway. But then again, I average 75-80. Ive been slowing down lately and it helps on long hauls

I dont think u'll such a dramatic gain in gas milage mainly because the newer vehicles use a plastic fan. on say, my 93 F150 it may be more noticable because it uses a heavier metal finger remover.

interested in this as well... my ranger is a gas pig..for mileage/ hp reasons... any hp gains? sounds like 1-2 mpg is about the most i'd expect as far as mileage goes..

what you probably will also want to do is wire up a DPDT switch to control the fan. I have one in my Jusnes Modified controller that in 1 position the fan is in auto mode, in the center (off) the fan gets no power, and in the other position the fan is forced on......

also, at highway speeds, you don't need to run the fan period.....that is what i added the switch......even with the A/C on at highway speeds, the efan isn't needed......


i didn't see any milage increase, but i did see a increase performance in the A/C during city driving, and i did see an improvement in acceleration and smooth running of my engine.....

Even if it is only 1mpg @ an eventual $4 per gallon, a Junses fan would pay for itsef in 40 miles. Think about that. If I was sure it would cool and hold up without breaking, I would buy one today.

since you don't offroad your truck, it would hold up good without any problems......i have had mine for over a year now and not had a single problem......i can guarantee you that the Jusnes fan cools without problems..............

I think your math is off, you mean when you get to that extra 40 miles that you wouldn't have gotten before the e-fan was installed, which could take 2-3 tanks of driving

Whatever. You get the point. It will pay for itself very quickly IMHO. Now if I can just come up with the money AGAIN. I had to spend some of what I had saved for it on, guess what, GAS!
