2010 F250 Coolant Smell and vapor out of the vents

[ifitssmokinitsstrokin]

I have a 2010 F250 With 35k Ive owned it since new and im having a coolant smell and steam/vapor coming out my A/C vents. It started with just a small smell Here and there about two thousand miles ago never really lost any coolant then the last thousand miles it started come and go then today it started the steam out of the vents but would come and go. I am thinking heater core? Or? has any one ever seen this on a 6.4?

My f150 did the exact same thing and it was a bad heater core.
