So last summer my original radiator blew. Huge crack in the top, snapped the upper hose bung.. it was a mess. I replaced the radiator, water pump and thermostat, didn’t buy the hoses even though I should have but I figured I could get by for another year and for the most part, it made it almost exactly a year. That said, it hasn’t been a year without issue unfortunately.
Ever since the rad. popped and everything was replaced, I’ve not been able to maintain pressure or capacity in my rediator. My cooling system is losing coolant somewhere, but I can’t seem to locate where. There are no signs of visible leaking anywhere on the motor, frame, radiator, water pump, thermostat housing, or heater core. There is no coolant in the engine oil, ever. I’ve replaced the oil in my jeep 4 times since the radiator blew, ne not one time have I seen any signs of water getting into the engines lubrication system. That said, it appears as though oil is getting into my cooling system though, doesn’t it. (See pictures)
My jeep never over heats, I mean never. I can run in stop and go traffic all afternoon in scorching Oklahoma heat and barely break 210-ish. I am at a complete loss. Now, here is what I do know:
I will be starting with a compression test tomorrow afternoon and probably pulling the top end off this weekend to check for cracked or warped head and/or blown head gasket. I’m guessing the heater core might have gone out which is likely where the coolant is going, but still doesn’t explain the no-start issue. I will update this post with results from a compression test as well as diagnostic codes. If anyone has had similar expenses, please feel free to share what you’ve learned and/or where to focus my diagnostics. Thanks in advance.

- Losing coolant somewhere
- During winter, turning on my defroster actually caused my windshield to be covered in fog. In fact, it’s like steam is constantly emanating from the center dash vent.
- Never has the passenger floorboard become wet.
- Thermostat doesn’t ever open when attempting to purge the system of air. Doesn’t matter how long she idles. It’s like she’s never getting to temp.
- I can “fill & purge” the system, top of the tank, a week later, there isn’t any coolant in my upper hose.
