After talking to the Honda dealer I realize that the drip and tube I found is the Evaperator drain tube and it was just dripping water from the Evaperator/ac system. No worries. It was the evaperator taking humidity out of the car and draining the water via the drain tube. It wasn't coolant afterall. Sorry for the false alarm.

Even though the inlet and outlet of the core get hot, that does not nessasarily mean the core is good. The inlet and outlet could be getting hot due to engine temp. If the core itself is not getting hot, Change it.
