I think the gauges ok cause he said he saw steam coming out and also water boiling.. two indications that something is wrong..
it could be the water pump as someone said before..
my problem started a few months back when there was some coolant coming out from the water pump.. but I waited to replace it later.. one day, in a really hard uphill I just heard a pop sound and the car shut off. One of the hoses got disconnected so there was coolant everywhere.. problem was that after the jeep cooled off and we tried to turn it on, it will turn on just fine but a couple of minutes later it was way too hot..
we replaced the water pump, thermostat, hoses, radiator cap.. we took the cylinder head to prepare it for the gasket and that was when they realized it was cracked.. I don't think there's a way to test a cyl head without taking it apart..
the Jeep has been running great after that repair.. it wont lose any coolant.. it wont overheat..
i just share my experience in case u have noticed something similar.. but you can start with the basics.. water pump, thermostat, radiator cap.. I learned those are common issues for our TJs. Mine is a 98 ..
