Hmm, I like it, keep me posted!
Thanks for the info!
I guess we don't get nearly that hot here, but its still something to consider.
I thought the mechanical fans were designed to fail in the "engaged" position, but I could be wrong (and probably am).
I'll be interested to see how this works out!
Maybe they can fail in either position.. I don't know for sure...but all of the ones I have had fail..always failed in the "NO WORKEE" position...
A properly operating mechanical fan / clutch setup is a very capable cooling system. It has been for decades.
Most of the perceived gains in power and fuel economy are in the head of the buyer. Dyno tests don't show much if any difference and I'd challenge anybody to show me where they got better gas mileage because of the electric fans. Maybe in the hundredths of a mile per gallon range. Maybe.
It's just so small of a difference that it amazes me how many will pay up the big prices to do it.
Well looky what I found on another forum.
You are correct Jim. Jenna has already told me in the past that you do get more horsepower, but its maybe 1 horse though. Usually not even noticeable, the same with the gas mileage. But I don't want to switch to electric fans for those reasons. I want much better airflow when my truck is sitting still, and e-fans will get me there. I already have the larger 34 inch radiatior in my truck. All I would have to do is unbolt my stock fan and shroud, and bolt in the new fans, then wire up this harness. The wiring will be a piece of cake once I find out which pins the blue and green wire connect to.
When did they switch to the eFans? Because I was very surprised at first at how loud the fans on my 2007 were. It really roars in a parking lot or at a stop light on a hot summer day.
2005 was the first year.
That explains why my 2007 is so much louder than my 1999.
In the fan world, more loud = more cooling.
Good luck with yours!
Nice find on the wiring diagram Scotty!
