Coolent vapor coming in through heat vents

Hi guys,
My 92 F150 with the 5.8 started smelling like coolent. We got out and looked under the hood, found no leaks or signs of overheating and it didn't smell like coolent under the hood, only inside the cab. Then we realized the truck was steaming up because the coolent was steaming into the vents. Did it worst on hot. So I am thinking heater core. What do you guys think I should look at first?
Thanks
Lars

Yep. Sounds (smells) like a heater core to me too. I'd fix it ASAP before it actually leaks into the cabin. Antifreeze is hell on carpet.

Yes heater core. Also can be dangerous if you put the defog on, on a cold day and suddenly you cannot see because the windsheild completely fogs up.

Ok guys, I took the glove box off and am not sure where the heater core is exactly. The truck has AC. There is the black plastic box right behind the glove box but it doesnt look easy to get out of there. Do I need to take the dash out? Or is it the box just to the left of that more over the trany hump?
Thanks for your help.
