Coolant leak help

So last night when I was walking our of the store I saw a small puddle of coolant forming under my jeep. After looking around the engine bay I saw it was coming out of a little spout that's located under the battery holder. Its at about 10-15 drops a minuet. It also is leaking from the inside on the passenger side from under the heating vent. I have no idea what i would need to fix or replace. My buddy said the spout might be a overflow spout for an overflow coolant tank but he wasn't sure. Any ideas?

(Pics not of my jeep) but that's where the spout is.

The spout is a drain from your heater/ac box that allows condensation to drain outside of the cab. If it is coolant, then x2 on the heater core going bad on you. They are not that hard to change out, but just in case, do check the heater hoses to be sure they are tight. They could leak enough to run inside, the out the drain.

Thanks for the input. Gana go grab a new heater core at Napa and swap it out in the morning and hopefully it will be good as new.

It's not bad to replace, look in the FAQ's, there's a good write up in there.

Edit: Here ya go.... http://www.jeepforum.com/forum/f12/heater-core-219329/ Might also replace the blower motor since you're already in there. I did the motor and not the core and about three months later the core started leaking...
