electric fan ?

I have heard of some people changing to an electric fan to get more power from their 4cyl. If anyone has done this let me know what the gains were and how much trouble it was to do.

It's easy to do, costs about $80 for the fan and controller and you'll get 1-2 mpg.

I have also been looking into getting an electic fan, or maybe even the electric dual fan... Any Ideas on costs and where to get them.

Thanks
Allan

Good question about an electric fan set-up. I asked on a different site and only got responses from guys with V-8 conversions. I would like to know the horsepower gains, mileage gains, and how well does it cool (compared with stock)? Even if it's only 10-20 horses, thats an improvement (a few horses on the 4 cyl makes as much difference as 30-40 horses on a bigger engine).

Here's a Thought, sell that POS 4 banger and swap in a 350 small block. There, horsepower problem solved.

Your horsepower gains will depend on the condition of the viscous coupler on your current fan. If it's old and seized you will see a better gain than if it's new and freewheels as it should. Regardless, clutch fans suck, don't work, and should be banned for all eternity
.
I did several bolt on mods all at once, so I can't give you a piece by piece breakdown. I ended up with about 7mpg better, and I can usually use 5th gear on the highway. My tires are 4" overstock and I haven't regeared yet. I haven't adjusted the speedometer gear yet, so I estimate about 18mpg currently. 15 indicated by my odometer. That's with my 4.0. I would imagine since it's a less powerful motor, you will get a better result percentage wise.

hrmm what about water resistance of the electric fans, I hear horror stories about the elec fans failing and overheating the vehicle.. also, is there a higher performance radiator out there over the stock radiator for the '93 w/ a 4.0L

I have been using my flexlite fan in my jeep for about 2 years now.. It has never failed on me without user error... MY jeep is a four cyl... and on the highway it seems to pick up speed with a lot more ease... thats about all you will feel with the fan.. one down fall though.. your temp will rise and fall dramatically.. (ie. 160 thermo.. 180-210) driving range.. 80 degree weather.. in other words easy cracked block if not cooled enough... and it tends to kick in every now and then when the jeep is off. people always think my jeep is still running even after i turn the key..
