93 Sunbird, it kept overheating, so I replaced the thermostat. Now it doesn't read that it's over heating, but now (and it did this before too), without having the HVAC system on at all, sometimes, it it spews forth steam/mist into the car, and it smells kinda like antifreeze. Someone unreliable said this same thing happened to their car, (non-pontiac) and they said it was the heater core. Help.
