Oh man, I know how it is. Had to do it twice to my own car and expect that I'll have to do it some more. Sucks, but gets easier each time and not taking it to a shop saves around $400 dollars.
If you're smell coolant in the car and it's leaking inside it probably is the core. Does your windshield ever fog up on the inside with some liquid that won't just wipe off easily (actually being coolant)? Try turning up your heat or defrost and see if it does it.
Just make sure it really is your heater core b4 you start pulling everything.
Now, you can just bypass the heater core in less than 10 minutes by going under the hood. Could just bypass it for now and change it a month b4 it gets cold in your side of the world.
And if you do buy a new heater core MAKE SURE YOU INSPECT IT AND THAT IT IS IN GREAT CONDITION.
