Would this be from the heater core? I don't have any leakage inside the cabin, but wondering if there is a drain that might allow a leaking core to drain underneath the car instead of poolong in the floor of the cabin. Car has not over heated and I flushed the system last spring. Or is soming from somewhere else I cannot see?

did you check/or have someone check the molded metal pipe that runs from the water pump to the thermostat. It could be rusted through at this point. I just replaced mine because it was badly rusted (was not leaking yet). Not a cheap part. Not available through a discount autopart store. Only available at your local for dealer and a real pain in the rump to replace. There is not much room to work with, especially with the 24V DOHC model. That pipe runs just below the serpentine belt just above the cowl on the passenger side by the front passenger suspension. Let me know.
