Add 850w heavy duty cooling fan to 3.6L Gladiator that didn't come with it. ( no Tow Package or Max Tow )

As mentioned(double check) in an earlier post the 2.0T has it.

I ordered mine 940 watt for a 2.0

With the 100a N5 fuse, easily. The fan is the only thing on it. 850w @ 13vdc is roughly 65a. 940 would be about 72.

I'd have to check our JLU, but I believe the 25 Mojave and the 23 4xe use the same fuse array.

And are you awaiting the order or has it been installed already?

2 years ago I spent 6 months trying different things to get my temps lower.
First a pusher fan. NO difference. The radiator core it to tight to push enough air though.
Than and 850 fan. NO difference. Fan only comes on at 15% at 221 degrees and 75% at 231 degrees.
To little to late.
Than I found RPM Extreme and Jon was making a fan controller for the JK and I ask if he could make one for my 3.6 JL.
3 weeks later I had a fan controller for my JL.
Game changer. My temps are 25 degrees lower both coolant and oil.
The highest temp I have seen is 212 under extreme condition and have never hit 218 which the fan will come on full blast.
I am now running the 940 watt just because I can and put the 850 watt and my wife's Rubicon along with the fan controller.
The larger fans are not going to make much difference until you take control when and what temps the fan come on.

Interesting and I do like this idea. But... I wish I could toggle it myself. Why? It is not bad that the oil gets up to proper tempereature on the normal commutes, because we only once in a while reach those upper temps when offroading or going on the Autobahn.
How hard is the install, cutting the harness seems easy and scary, and do you reckon they would make one that you can toggle or set the perimeters? I guess one could make a bypass, but it does introduce another thing to fail... kiss seem different. I know, overthinking it

now running the 940

I am curious, was that just normal install, or was there anything else needed?

Just for reference: our 2022 JTHAD (High Altitude Diesel) came with the 940W fan. This model is truly a “hodge-podge” of parts from all the model line up. ‍

but it would make sense, as the diesels did run hot anyway

That's a shame about the price jumps. Honestly though the temps didn't get wild during this summer's heat wave, and the small alternator seems to keep up with everything and my lights fine so I guess this has gone from a back burner to a very back burner mod for me.

It is very easy to install. You only cut one small wires that goes to the fan.
The other wires you strip back and solder wires on to them.
Nothing else is needed.
You will be surprised how well it work even with a 600 watt fan.
