When I tow my camper with the AC running and going up even a slight grade my engine temperature gauge climbs. This has also happened on the trail a couple of times with the AC off. So I used an old trick that truckers used to use. Some motorhomes also use it in the mountains. A radiator mister!

Here is a 2.5 gallon water tank with a 12v pump on it. the water line runs up to the next picture.
Image

Here the water line has split into 2 lines with a sprayer head on each line. I think this will work where it is but I might have to move them later on. Just drill out the rivets and move the heads.
Image

This setup is supposed to drop the water temperature by 40*. I know it doesn't take much to cool down a hot radiator this way so I'll just cross my fingers.

I'm watching it. So far it's not leaking. I did find out that I have to use a funnel though!

Have you tried getting all of the mud out of you radiator? Ive never had my Jeep over heat towing anything. So far the heaviest thing Ive towed is a 4k boat, which the 3.7 didnt like but it never got over 200F on the hills. If that gauge is moving then youre getting over 230F.

I have cleaned it from both sides. But, maybe I didn't get it all out.

Do not let that water hit the plastic side tanks,they will crack!!!! Actually keep it well away from the sides of the radiator.

This theory works better with a all copper radiator or a all aluminum radiator.

Adding trans cooler would probably be a good way to go, trans is most likely producing the heat problem and best fixed at the source.
