2X 10" fans might not be enough by themselves unless they are extremely high speed fans. I forget the exact number but I seem to recall somewhere around 4000CFM being the minimum which gets recommended.

 

I thought the usual way of wiring an electric fan setup is a 3 toggle switch with ON, OFF, and AUTO. That's how my co-worker is doing his jeep as we speak.

 

that is an interesting way to do it. most wiring diagrams usually say wire it up for auto with a bypass switch. none of them usually setup an off position.

right now i just got mine hooked up to my cruise control switch to turn it on and off. i find as long as i keep moving i never need them.

 

He's got off road use in mind, but also keeping it interstateable. I just invented a new word.
He's actually driven it to work a few times with no fan hooked up, and it never reached above 200, probably because of the new fancy aluminum radiator, as well as the fact that it's a 4.0 of course

 

i got a 195* thermostat in mine and my temp gauge usually never goes above 200* with no fans running as long as i don't have to sit at an intersection for much longer than 30 seconds and i have the stock rad. 2/3's of the driving i do with my truck each week is highway and it does good but i wish i had installed the 180* thermostat.

 

Thats the same I was thinking. That's why I was going to just turn them on when I need them, and that's only with the plow on going down the highway.

Mainly wondering if they would give the little more airflow through the rad for only that reason or if they wouldn't really do much.

 

But they wont do anything in addition to what you've got unless they are more powerful to begin with...

 

Thats where Im stuck. I know they're not stronger, but I was thinking since they're mounted directly to the rad they might accually pull some air through. I think its going to be a trial and error thing, put them on and just see if they do any good when needed. If not, I'll pull them back out and chalk-up some expirience.
