Heater core leak?

[smittyfromPA]

Hey all, anyone have a heater core leak in their KJ? I've noticed a growing wet spot on drivers side floor lately. Being winter time I chalked it up to my wet boots. Well, Jeep has been garaged for a bit and everything dried out but this area. Cant tell if it smells sweet but feels oily. Any advice on what else to check for to confirm? Heat seems to work fine. KJ has the best damn heater of any vehicle I've ever owned. I had a post up here a few months ago saying i had low coolant but no visible leaks so this all makes sense now.:favorites68:

Just realized i posted this in KK forum, my bad!

I'd pressure test the cooling system and look for leaks in the area where the carpet is/was wet. You might get lucky and all it is a clamp or hose going to the heater core.

hmm...... coolant does have that oily feeling.
Maybe it's a clogged sunroof drain i f you have a sunroof.
