I suggest that the cooling system be fully tested by a professional who can also test things like blockages, thermo operation and even the flow of water around the system. etc
Perhaps your sensor(s) my be in question too...
Correct, it shouldn't be an issue but XJ's and TJ's are prone to overheating, the XJ is worst with it's very short radiator.

I run in low on the beach most of the time but also have a heavy duty fan clutch, AdRad radiator, new hoses, regular coolant and radiator flush and as of yesterday a new water pump. I can run on the beach all day with this setup without overheating and that includes flogging it up the dunes. I also run at around 10psi with the 35's and am regeared to suit them. It eats the beach up now and when we did the last clean up day there it was pretty much unstoppable when aired down to 10psi and could drive around (and snatch out) others that were bogged

Sooo, in short, give the cooling system a once over and check the fan hub clutch as for me that made the biggest difference to running temps.

Cheers
