electric fans

[pitsingerk]

Has anyone here removed the motor driven fan and installed electric fans. I've read articles saying that you can get 1-2 mpg by doing the conversion. If you have, has there been any overheating problems. Before I spend the time and money, I wanted to see if anyone else has done this.

Iv only heard not to that they dont properly cool a diesel i would stay awayfrom that mod there is much more in the way of programming that could give you that gain and would be safer and you will enjoy a programmer more for the money you would spend on e-fans my .2 cents

ive done it , it has to take some drag off the engine , is there a way to get a couple more miles to te gallon , its doubtful, i like my electric fan, ive had no over heat problems

Scuffy is a TechyMod. I would listen to him. And I cant think of any reason they wouldnt cool just as well or even better then the stock fan. They move just as much air or even more.

I've done the programer, exhaust from the turbo back, and intake. It took the truck from 12.5 to 14.5 mpg. Thats good, but at 3.30-3.60 gal for fuel, I'm looking to get better. The truck is a 97, 5spd, 4:10 gears. I'm not pulling as much as I used to, so a set of 3:55 gears are going in soon. I'm hoping that change will boost the mpg also. In Diesel Power magazine they did an article on a cummins powered truck and got 1-2 mpg increase.

Then go for it.

I removed my fan last year and run with out one. Last summer I drove up to MO from TX pulling my all steel car hauler with my 94 Lightning on it doing 70-75 all the way there and back. Did not get even a little hot. The only thing that sucked was the A/C when the truck was not moving. So I'm going to install a electric fan so the A/C will work at a stop.
