XJ Coolant system leak
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?

Hopefully you didn't warp the head after it overheated

Re: XJ Coolant system leak
Would'nt I have a head gasket leak or something if the head warped?
There's no water in my oil, no funny exhaust or anything out of the
ordinary except I loose coolant and can smell it in the cab once its
heated up.
I figure the problems with the heating system and I need to rip into
the dash find the core and any visible coolant lines and try to find
the leak. Sound like a plan of action?
Thanks

Re: XJ Coolant system leak
Ouch!
I would first look really closely where the heater hoses go into the
firewall on the passenger side for a loose clamp or pinhole in the hose.
Otherwise, smelling it inside means the heater core has gone bad. This
isn't a fun job to change...... The console and whole lower dash have
to come off to get at it. It is a 'full' days work usually.
