Have you tested the actual temp of the fluid in the rad??

Is it possible you have a bad gauge AND a heater core issue????

Upper and lower radiator hoses are cool to the touch. And this problem happened instantly. If you turn the engine off the upper hose starts to get hot and you can turn the key on and see the gauge get hotter. Do you you think it's a possible circulation problem? Water pump or radiator? I would think it would run hot if it was. The temps here are in the single digits wich may keep the engine cool. A week ago I had good heat in the the same cold temps.

Something is plugged OR your waterpump took a crap. Your gonna have to pull everything apart to flush stuff so you may as well pull the pump off and check it out while your at it.

If his temp only goes up to 125 then engine is not getting any coolant. I would remove the themostat, start the engine and watch the coolant in the radiator to make sure the water pump is circulating. if coolant is circulating then put a new stat back in and drive it to get it up to temp. The new stat you have may be bad.

If his engine was not getting any coolant then the engine would over heat. When a water pump goes out the engine over heats not cool down. It is possible that you got a bad stat. I've had that happen before. You said the hoses don't heat up until you shut down. Does the radiator get hot? This is an odd problem unless the radiator is blocked but the engine would then over heat. Does the engine seem to be running alright? Loss of power or anything?

Glad you got that fixed. It is not uncommon to get a bad Tstat.

It just makes sense that is was a bad tstat. If the tstat was stuck open even slightly then coolant would continue to flow threw it not giving the engine a chance to get up to temperature. When you shut the engine off, the temperature would begin to climb since the coolant would no longer be moved via the water pump. I'm glad you solved your problem and that is was a cheap fix.

I was pulling my hair out trying to think of what could be causing this.

I have been following this post because I have the same problem! Jeep gauge barley moves... I replaced tstat in summer and it was OK but now that it is colder I have very little heat! Looks like it's time to hit Napa for another tstat! Thanks for the info!!!
