electric fan

[47papa65]

what ,if any are the advantages of installing an electric fan on a 4.0 v6? will it help gas milage or run cooler at slow speeds?

It will help mileage a bit (supposedly) because that weight isn't dragging on the engine, I'm not sure how much of a difference you will see though.

We like them up here because we can turn the fan off when in submarine mode, a propeller does no good under the hood.

I agree, when in submarine mode you sure do not need the propeller screwing thing up ! Especially when you raise the periscope.

It will also give you a few more hp

IIRC, most of what i've read says the stock fan still gives the most cooling. it's supposed to have been designed to keep that engine at the correct temp during different driving conditions for which it is warranted. guess you have to be real careful to make sure the electric is the right size, ie: adequate rpm's and volume of air moved to have the same cooling effect. as i don't do any mudding or swimming with mine, i'll be leaving it stock.

Hello

I did it to my 2.8l and it does great. I will do it to my 2.9l when the time comes. Look at the mustang fourms for info on high flow fans.

POTENTIALLY increase all around performance


provided
PROPER INSTALLATION
is part of the scenario.


if you need to cross water, or are doing allot of drag racing in stockish classes or do mostly long hiway commutes 100 miles a day, it is a 100 percent winner.

if all you do is drive 6 miles to work most days its a piss-waste of your time.

If you do this, don't cheap out. Your new electric will hve to move a butt-load of air to keep up with the stock fan. You will notice no HP increase in your hinney dino. You will notice no substantial increase in fuel milage. The savings in drag will just be transferred to the alternator. Reliability is much worse with electric. If I did not need to shut mine off for deep water, I'd put the stock fan back on in a heartbeat. Unless you have a particular reason to switch, I wouldn't bother. Any gain you might see will be more than offset by the cost and trouble of the installation.

keep in mind that a stock fan without a shroud is nearly a waste of time. and electric ones always are shrouded so guys that see a huuuuge improvement with an e-fan is because their shrouds are damaged, missing or incomplete to begin with and so the stock fan isn't working.

i have 2 14" e-fans on my 1988 with a v8 swap. and they move a "buttload" of air.

i think it is 6 of one, and half a dozen of the other.

My only thing is to the reference of moving a "buttload" of air. It just has to move the same CFM's as the stock fan. no more, no less. The thing is definitely having the shroud and the proper size/rpm fan so that you actually are moving the same amount of air.

My point is that most of the "cheap" fans out there move nowhere near what the stock fan does. If you have an auto trans. and are doing a long, slow climb, that crappy electric won't keep up. Like I said, don't be cheap. I've had pretty good luck with the stock Taurus electric fans. Dependability is much better, they move lots of air, have their own shroud and they are two speed. I usually wire the "high speed" to a manual switch and just use it on those ling climbs I mentioned.

I have a taurus fan around here somewhere, guess i better build the dang truck so you dont have to see it sitting there everytime you drive bye.

reliability is potentially worse. done right it is better.


the savings in the always drag is not always transferred to the alternator.

the unloaded stock unit always pulls about what the full on fan pulls.

then again its all application specific.
