Ok i have searched and could not find anybody talking about it. I am planning on putting a set of e-fans on my 02 4.7L ram 2wheel drive, my question is, is there anyway to hook them up where they come on automatically (is there already a wire harness for them, i haven't seen one, or would i have to wire into something else that comes on when the truck is turned on) or will i just need to hook them up and use a toggle switch? Which way is easier and or better.

And also what is a good setup to buy new, aftermarket or used off of some other model or engine. I have seen a combination (both on the truck at the same time) e-fans and clutch fans on some of the newer 2010 hemi's, would one of those fans would or do they have both cause the e-fan isn't strong enough.

 

Don't use just a toggle switch, first time you forget to turn it on, your engine is toast.

You didn't search very well, cause there are hundreds of threads on e-fans, including a complete DIY or two in the FAQ section.

You can get you a good pick 'n pull efan out of a Furd Taurus or Mark VII and a controller kit with probe off ebay.

But I think you should spring for a new kit like the Flex-A-Lite, since it comes with everything and has some real good documentation (which it sounds like you need).

Also, the electric and clutch fan you refer to is also on 3rd Gens (and 2nd Gens). The engine cooling fan is a clutch fan, the e-fan you see is an auxiliary transmission cooler fan...

 

so what do you think the best setup from flex-a-lite would be they have a few different kinds. i have never converted to electric fans on any of my rides yet so i don't really know the size i would need to put out enough airflow

 

My question is , Is the stock fan not cooling your truck why do you want to swith to a electric fan? If it because your truck runs hot the 02 4.7L radiators are junk they clog up. Not trying to sound like a smarta** I'm just wondering?

 

no my truck isn't running hot. i put a new radiator in a few months back (old one had a leak a new one was cheap enough i just replaced it) but what i have read they do keep your truck a little cooler so really i just want the e-fans for when i am sitting in traffic stopped on the highway and it takes stress off the motor

 

ok got ya makes sense

 

This is the one I have http://moesperformance.com/index.php...products_id=15 and like Hammer said it has everything you need all in one box. Pretty much plug and play but alot of guys on here went with the Taurus "junkyard" route and it has worked out well for them. If you do a search you can find all kinds of information on those. Its all your personal preference.

 

Is it pretty easy to install the complete kit?

 

Yeah, it's not a hard install at all. Personally, I thought the hardest part was getting the stock clutch fan off. I also have the 180 Extreme, which I think has recently been discontinued for the 183 Extreme.
It's cheaper to go the pick 'n pull route for sure, BUT like stated you get everything you need with this kit, good documentation and the Flex-A-Lites pull more air (3300 cfm) and less amps (around 18 vs. up to 50 for some of these junkyard fans).

 

Well chit, let me chime in and be the odd ball.

I will be the cheap **** on this thread. I have a Ford Taurus fan from the junk yard ($25) and a Hayden fan controller ($40) from the auto parts store. You can have it wires where it gets power only after the ignition is started or do like mine and let it continue to run after the ignition is off.

With my fan and a 180* stat, this is where my temp gauge sits all the time
