Overheating to make the engine stall. If I run the heater full blast, it will get hot, but not stall. And no I do not drive the car, that is what happened on the day I had to get it home after first allowing it to cool off and adding water. I can't tell you what temp as the temperature gauge does not have numbers on it. Normal operation temperature for the car had the temp needle under the half way mark. The Temperature gauge never registered that the car was getting hot. That is why I did not notice any issue until the car stalled at a light.
No, I never lost heat from the heater vent.
No air pocket, all air was release from the system.
The Dodge Intrepid does not have a radiator cap. The only cap is on the overflow tank and the plastic is to thick to see any bubbles. There isn't any steam coming out of the tailpipe and there isn't any water in the crank case.
This car has been well maintained and I only use synthetic oil.
I have taken the car to a mechanic
to do a diagnostic on all the sensors
etc, check the catalytic converter etc.
The cooling fan is working. That was the first thing I checked.
I would not be on this forum if I had any idea what was going on. I have checked everything that would normally be a factor. Everything that has been suggested to me so far was checked before I posted to this forum.
What other internal issues are you speaking of?
