Cooling Temperature Problem

I have a YJ 1990 2.5L we bought it four years ago. Bought alot of new parts for it to make it run. I ran the jeep one day and it over heated. Got coolant and water and filled it back up anddrove home. Found the cause of the problem, leaking on the bottom hose. Every time I drive the jeep for a long distance the temperature goes right bewtween 210 and 260. Is that normal temperature reading? Kind of worried please assist me on some knowledge for coolant temperature. Thanks

210 is the normal temp for a 2.5L. It will run all day long at that temp with no problems at all. If it is actually running in the 235ish range then you have a cooling problem.

But i would suspect that its more of a faulty gauge reading than running that hot. The gauges in a wrangler werent the best design that chrysler ever come up with. They work fine when they are new, but there are so many flaws in them once they get old that they are more of a joke than anything.

Go to autozone or someplace like that and have them hit your motor with an infrared thermometer if you dont have one yourself. That will tell you what your motor is actually doing.

IMO if you are running that hot, it would be running very bad, cause the fuel would be vaporizing before it had a chance to get to the cylinders. And the paint should be getting ready to peel off of the hood too...lol.

Appreciation

Thanks I think your right, I was reading other threads about faulty gauge. I'm not to sure though if I messed up the head cylinder though. Because of the over heating issue I had in the past. Anyways thanks for the tip greatly appreciate it.
