Late last winter I had a freeze plug blow and the Jeep overheated a bit. Since it was very hard to get to I just replaced it with a rubber freeze plug. I dont know if that has anything to do with it, but it seems it might.
I now loose coolant and can smell it in the cab when the heat is on but the core still puts out good heat.
I'm not familiar with the heating system and am wondering if there is anything besides the core that could leak. Anyone have any suggestions or guesses?
