Im converting my mechanical fan to an electric one because after reading it seems like a good thing to do. plus my mech clutch is on its way out so i figured it would be a good upgrade. I went and bought a stock e fan from a cherokee. I was going to the taurus upgrade but it seemed like to much fab for me. I found plenty of write ups on how to mount it but not anything on hooking it up. Could i just splice it into the other stock e fan that comes on at 215F? I really dont want to do a switch cause i could forget to turn it on. I also saw there are temperature triggered switches but they are $30 plus. Im wondering how people hooked up there double e fan and if splicing it to the other stock ac fan is a good idea. thanks!

The fan gets triggered at 215. Is that too hot or is that okay?

I run both of my stock efans on switches, I thought I might forget to turn them on but have yet too. I also always find myself looking at the temp ha

i run a taurus fan on my rig, and a manual switch for the aux fan so i can turn it on as i please

Your in Texas like me, so how is your temp while idleing or crawling?
I want to do an efan to replace the mechanical fan but don't want to lose the good cooling capacity

Bad idea... The stock e-fan moves nowhere near the amount of air that the mechanical fan does. 2000 vs 5000 CFM if I recall correctly. There really is no comparison and you'll likely overheat. The Taurus fan is around 3800 and much better suited for this application.

I'd have one permanently running on the driver's side to cool the exhaust manifold, and move the aux fan to the passenger.

I have ran two stock efans on two xj's with no heating problems, & it gets pretty hot in the Nevada desert in the summer...but I guess anything is possible

After all the write ups I read I've never seen someone have a problem with the double electric I've only found good things about the dual electric.

How did you wire up the fans?

At what rpm is that 5000 cfm? Is that at idle?

You crawl a lot or just go on the highway? Manual transmission? I'm just reading out the specs dude.

No that's something like 3000 RPM. I do not remember the specifics. The point is, the XJ auxilliary fan is just an auxilliary unit for backup purposes.

By Dirtbound Offroad's own testing the dual stock efan setup moves more air then their 3 fan setups. The dual 99 efan setups that had maxed at 5300 cfm. Thats irregardless of the engine RPMs. Seems sufficient.

Got the fan installed and all wired up. But i cant get it to work with the ac fan. I have it spliced into the positive of the original fan and to a relay. I know the relay works and so does the fan. I did some reading and it turns out the ac fan works by the pcm grounding it out. Could i tap into the ground and run power to the relay to act like a switch? i gotta finish this tonight so any help would be great

how can you question something I've done a few times with great success & You've just read some specs..
