1998 TJ erratic gauges

I have a '98 TJ and yesterday took it for an hr. drive. On the way, I noticed my temp gauge going from 210 all the way next or on the red and it would say "check gauges on dash. Also I noticed that the oil gauge is also erratic so as my gas gauge. Well, on my way back home, I didn't make it as my temp gauge went up again all the way to red shaded area. Pulled over to the nearest safe area on the highway and turned the engine off. I heard like boiling water and as I opened the hood it was spewing steam from overflow tank. Got it towed home. Next day I flushed the radiator and replaced thermostat but when I took thermostat case, there was no thermostat on it, makes me think, so why did it over heat. Anyway, took it for a test drive after I replaced coolant and thermostat but after 15 min of driving my temp gauge went up again next to red and my oil pressure went down to below quarter or 0, my gas gauge light went to empty when I know I have 3/4 tank of gas. Any suggestion on what to check or replace?.

Have you checked the engine oil?

I had a similar problem some months ago and my problem was a cracked cylinder head..

You might want to pull the water pump as well and make sure the blades are not shot. If you search here on the board you will find some pictures of what I am referring to.

Engine oil level is good. Does not even burn oil. Oil level has anything to do with overheating and erratic gauges?.

May be something as simple as pulling the dash cluster and cleaning the contacts. Does pushing on the dash affect the erratic guages? Very odd for 3 unrelated issues to occur at once.

Not sure about what it means by fan working. When I start the Jeep,I could see the fan blades rotating. Is that what you meant?.

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 ..

Have you pulled the water pump yet?

Found these pics here on WF at this link. This is what i was referring to about the water pump blades being gone.
