December 11, 2010Anyone do a swap out of their stock fan for an electric one? Is it expensive? cost effective? any performance gas mileage changes?

December 11, 2010Def. a difference. You need a dual fan application especially if you tow. You can find LS1, or LT1 fans on ebay all day long for a good price and it`s just a matter of wiring them up. I believe nelson performance makes harnesses you can use and even have them tied into your pcm.
I think they are worth it. Less drag on the motor and a little more power and mpg.
December 12, 2010I love mine. Throttle response was amazing after I did mine
December 12, 2010Thankyou for the info. I also do snowplowing with this truck. Is that going to be too uch of a drain on the truck?
December 13, 2010I put LS1 fans on my 98 a year ago, bought a wiring harness from Summit Racing and it is controlled by a sensor I bolted into my water neck. Throttle response was the biggest thing I noticed as well as all the additional room I got from having the shroud and fan removed.
Only problem I had is I was running underdrive crank pulley and an overdrive altenator pulley, and the fans kept killing my battery. So eventually had to get a new battery as well as a change the altenator pulley back to the factory one.
Snow plowing with them should be no big deal, I had my truck close to 250 once but I was in a huge mud pit and wasn`t giving my truck any mercy. I don`t think the factory fan would`ve been able to do any better... Just be sure to watch that it will charge properly.
December 13, 2010sounds like its worth looking into.i have heard both ways on it. but if i had it i would consider it.....
December 13, 2010Of you could, Don`t get the wiring harnes that is controlled by sticking a temp prob into your radiator. To me its tacky and they seem to all ways start leaks.
December 14, 2010why can`t you tap onto the existing temp probe for the temp gauge in the truck to run the fans
December 14, 2010I suppose you could, but what I got came with its own probe and its after the thermostat so it allows the coolant to start ciculating before coming on.
March 6, 2011I am now hearing mixed messages after doing more research. Some people are saying that my truck should have an electric fan. I look under the hood and see a large fan with a belt on it.......thats not electric right? It is a 2006 2500HD with the 6.0L.
March 6, 2011no thats not electric. but im still interested in it just no funds heading in that direction. if you do it let us know what the results are.
March 6, 2011I`ve been doing a bunch of research on this. I`m wanting to do it just rather put funds elsewhere. I know someone who did it on there truck 2500 6.0 as well. Did dual 16 inch I believe and wired them up to thermistate thing so if coolant reaches certain temps thell go on. I dislike it because in the summer the ac doesn`t get cold till the trucks hot enough to kick the fans on. I have the fan of a duramax on mine cus the stock one went out and honestly its stupid the power loss and mpg loss not to mention the strain it puts on my tranny with it shifting at weird rpms when the fans on. I drive around with no ac on and windows down till I start pouring sweat just to avoid it being on. Does the wiring harness make it factory like when you start the truck they kick on etc...??
