That's the stock XJ electric fan. Hopefully getting. 2nd one tomorrow

 

I wasn't hating on anyone's ideas. Just strictly asking why not always on. I get the idea of having it kick on at a certain temp...

 

Anyways, looking good. Interested to see how it holds up to a decent sized trip. You gotta report back after a day of driving.

 

I'll be taking it to work tomorrow and then to pick-n-pull. I'll keep everyone updated

 

I just did this on my own. I'm running the stock Aux fan as is and a second OEM Aux fan on a Derale adjustable thermostatic control that's also tied into the A/C clutch so both fans run when the A/C is on. I've been driving mine back and forth to work all week and it's never gotten above 210 so far. It's only been in the 40's here though so the real test will be this summer.

 

so whats stopping me from buying this fan, and wiring it and my second smaller fan (the stock ac fan) all to run off the temp sensor in the therm housing on my 4.0.

Does anyone know exactly how to wire it so it works?

 

You could try but I don't know if the fuse and relay can handle both fans. That Hayden kit I ordered is made for 2 fans that are no more than like 20 amps each

 

Nice work and your work looks clean. Theres a few months ahead before you can really "test" its cooling ability but I bet she'll do fine.

 

Thanks! It should be ok. I just got the 2nd fan this morning and was in the middle of the install when the wife shut me down. Lol

 

Done and working like a champ!!! Also picked up a new (to me) coolant tank

 

I am thinking of trying this on my ZJ.
Looks pretty straight forward. i was thinking of grabbing a switch from advance auto parts. It has a setting for temp right on it too.

Thanks for posting this up.

 

No problem. It was extremely simple. I needa make some brackets to get it bolted up. I cheated...it's zip tied in right now. Lol

 

im also getting ready to try this but im using the newer stly xj fans ive already changed the aux one they pull alot more air than the older xj style..

 

I did not know that. If I have issues then I know what to do. Thanks for the info!

 

all you gotta do is butt connect the newer fan plug from the old that way you still have the factory wiring harness plug i swear they pull like double the air from the olod just make sure you wire it in the right direction...
