99 XJ 4.0L
I recently replaced the entire cooling system: new CSZ radiator, gates water pump, thermostats & thermostat housing, overflow bottle, and hoses
I hooked everything up, and poured about 2 gallons distilled water into the radiator cap.
Started it up and let it sit for a few minutes. Coolant didnt seem to be flowing, I stopped the jeep and the manifold was freakin hot!
Started it again, and this time coolant just started bubbling out of the radiator cap.
I've started and stopped it several times now, and let it run for several minutes.
-The temp gauge seemed stuck at 1/4, yet the engine bay feels fully heated.
-Turned the heater on full blast and it was cold air.
-The upper radiator hose is not warm, and I don't feel anything flowing through
Is it likely the t-stat is stuck closed? Is it possible an air bubble is causing the tstat to stay open, and to not move the gauge past 1/4?
