Depending on how bad, and how long the orginal core leaked, it might just be residue in heater box, and if it got up into the vents, it will take awhile for it to dry out.

I have white smoke/steam coming from my air vents and antifreeze leaking from a spout in my firewall. Any ideas/solutions?


Your heater core is leaking steamed antifreeze into the vents and possible out the firewall,where the heater hoses connect to it. Have that checked out.

Heater core


Sounds like a bad heater core. You will get steam/vapor out of vents from this. If you are referring to the over flow tube being the evaporator drain tube at the firewall its because the heater core shares the same case with the A/C and its filling up with anti-freeze.

Put antifreeze in car and now smoke pours out of heater vents.and overheats


This sounds like a blown heater core or heater hose. If you smell antifreeze and/or see a puddle under the car or on the floorboard, you would most likely have a heater core gone. This can be a time consuming repair due to the fact that the core will normally have to come out under the dash area towards the floor.

Antifreeze steam comeing through vents


Your heater core has a leak, it's like a small radiator that heats up and the blower motor blows air thru it to create heat in the car. It is leaking anti freeze into the heater box.

Smoke coming out vents when defrost is on and temp gauge goes up and down in 1994 Taurus


The fluctuation in the temp gage indicates a low coolant situation. The smoke you see from the defroster vent is actually antifreeze that is leaking from the heater core somewhere and as the antifreeze evaporates from the heat it causes a vapor to produce. You should smell a very sweet smell when you see the vapor. If so it is definitely antifreeze. Find the leak and fix it. Then refill your coolant system to specs and you should be good to go.

Antifreeze smell and smoke coming out of vents


You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.
