Electric Fans On A 2006 6.0l

masterp2 · May 24, 2010

... from what i have read and heard some of the electric fans move more air than the clutch fan setup.

Just the opposite is true. The thermoviscous will easily move 60% more than the best electric you will find. On top of that reality, here's another. Your alternator will fail twice as often, unless it is upgraded.

If you have no hills, you may be fine. I don't know what part of the country this will be, but if you were here and tried to leave our valley, you would get stranded between now and October.

FWIW.

I know this is an old thread, but briddle3...dont listen to these guys. I did the conversion, and its great! Cost me under $450 for the kit, can give you website if u want. I have a 2006 GMC Sierra 2500HD, got dual fan setup with all wiring and relays (no need to connect to PCM) and did the install in couple hours. The toughest part was getting the mech fan off. There is a little dial on the relay to have the fan come on sooner or later than you want. An the is a thermoneter stuck right into the radiator to control the fan on/off. I haul a heavy trailer daily, and have bigger than stock tires on, AND fill the bed heavy all the time...no problems with cooling. The temp always stays a cool 180-200deg.

Tooch, glad to hear your setup is good. What part of the world are you in. I know from living down south and out west, when the temps are in the 90+ range (in GA) and in the 100+ range(SoCAL) cooling was real hard. Not saying it can't be done. I just know that the stock clutch fan while not the most power saving type, has been noted as one of the best cooling setups. Also when I was over in Kuwait,Qatar, Saudi, and Iraqi, the uparmored 3/4ton Burbans with the stock setup had no problems keeping the engines cooled, and this was for both the 8.1L and 6.0L. The temps in those places did easliy get into the 110-120. But back to your setup, I am glad to hear your setup is doing fine, I just have never hear a electric setup being able to pull as much air as the clutch type and it has made me look away. Can you give more info , and tell me how much CFM yours pulls vs the stock setup? Thanks!
