I couldn't tell you if you they do or not but I know you can have pretty much any size rad built so I imagine finding something bigger wouldn't be hard. Is there a reason you need it?
There's nothing special we use out in our local deserts that regularly get >100 degrees my TJ stays right at 210. Why do you believe you need something else?
Towing my dolly with a 2700 lb car on it yesterday it got hot. Not sure if the thermostat stuck or what, but the water pump was done about 1k miles ago along with upper and lower hoses. Rad looks good, its in my 06 with 137000 miles. It pushed all the coolant out in the overflow and from overflow onto the ground. Had to limp it home coasting to cool it down, it had coolant just was low and I had nothing with me and it was way too hot to put anything into it. Gotta figure out why it decided to overheat when it towed 2 days no issues, only this time I had to ac on and was on a slight incline.
I've often wondered why nobody has reproduced the 7-blade fan kit you used to be able to buy directly from Jeep if there was any functional benefit to it.
i dont tow with it often, but i had to use it for a short tow, 60 miles. ive towed with it before for 4hrs straight and had no issues. the radiator cap is original. rad is original. it always runs at 190 or a hair above when its been running on normal driving, hard to peg the number exact without a digital gauge. i had towed twice on it and it had not gotten hot at either of those times on friday and saturday, but sunday it did this. could have been a combo of things, i had the a/c all the way up and it was somewhat of a grab but im talking got to 260 not just a little warm. even when the water pump went it didnt get that hot, but it was also winter.
Radiator got replaced, mechanic said top was corroded inside. Stays cooler now even
