definatley antifreeze,,,heater core..hose...freezeplug..

get a pressure tester and check and see if you loose pressure and that will give you a good idea.

go to auto zone and get a pressure tester....pump it up..let it sit for about 5 min...and look at the pressure..if it goes down the you have a leak....then the fun part...find the leak

Seems like it would pop out of your head :clown:

Might be just a connection barely seeping coolant and a lot of AC uses the heater to regulate temp and it's evaporating off, if you don't notice a coolant loss. I've had a leaking heater core a few times.
