    BlackBetty, I'm not thinking much, if any. Yes, you're pulling the strain off the main belt of spinning a mechanical fan. But, you're just transferring the load to the alternator, which then has to pull more mechanical power off the belt to generate the electrical current to support the fan. That being said, when I get the chance and the parts, I'm going to perform this mod myself, along with a hearty electrical system upgrade.

    LOL You dont like the way people stare when you take off from park like you are about to run them over cause the truck just roared at them or that it sounds like you have air boat under the hood at times

    I have the factory flex fan with a severe duty clutch fan and it does all the above LOL


    Poor people just swivel their heads around like its coming for them

    Exactly, i just hate the sound. i was going to put a clutch fan to quiet it some cuz i didnt want to spend the 400 dollars for an electric fan setup. but this setup seems cheap and reliable.

    I used an efan off a grand marquis on my 03 silverado. Fits perfect and covers the whole radiator with the built in shroud. I have mine running all the time with just a relay and have had no problems. Been about an year now, but they do make ALOT of noise. Sounds cool to me.

    I had done this to my 'burb after the engine rebuild using Mike's original "how to". Best conversion I did for that old truck. The engine temp used to run just about 210, and with the electric fans on medium speed the engine temp was like 175.

    My fan was from a ford Taurus I think. Not sure, the bone yard guy just brought it in and said this fits the measurements you gave me. I completely covers my radiator, and depending on how it's wired up it has multiple speeds. It's a dual fan unit, if anyone is wondering.

    Default Electric fan swap Made easy

    nice solution. I have mine on my clutch switch also, just because Im lazy and its easy for me to get to. Im not familiar with the lastest auto tranys. Is the neutral safety switch still in the cab or down under the jeep now?
