through a cracked heater core - possible.
It could be a partially blocked heater core, a faulty heater valve that allows the coolant through the heater core or it could be a faulty water pump.
A good chance you have a faulty heater core
Antifreeze is used as an engine coolant. While keeping an engine from overheating, the liquid also disperses the heat through the vehicles heater core, giving passengers warmth in the winter.
Sounds like your heater core is bad and your engine is low on coolant
Your car shouldn't "burn" antifreeze. If it actually is "burning" antifreeze then chances are you have a blown/leaking head gasket or possibly a cracked engine block which allows antifreeze to enter the combustion chambers. If your antifreeze is just disappearing then it is probably leaking out from somewhere. Possible leak areas to check out would be the radiator hoses, heater hoses, radiator, water pump, and the heater core. Most of the time if the heater core is leaking you'll be able to smell the antifreeze inside the car while the engine is running and the heater is on.
Your heater uses somthing akin to a mini radiator to transfer heat from your engine to the cars interior. However, if you're smelling antifreeze, you have some type of leak.
Blown Heater Core - The heater fan blows past the heater core and if it has a hole in it your antifreeze ios being blown onto your windshield.
That is probably antifreeze steam. Your heater core is a small radiator used to heat your car. The engine heats the antifreeze and circulates it through the heater core. Your blower blows heat through the core (radiator) into the car, and warms you. If the core gets a small leak, it will put out steam.
Antifreeze will be leaking in the floorboard on the passenger side, there will be a smell of antifreeze through the vents.

No. The top hose goes to the engine. The bottom hose feeds from the engine to the heater core back to the radiator.
if you have the heat on in any vehicle, and there is only cold air coming out of the vents (providing the engine coolant temp gauge shows that the engine is warm) then there is no antifreeze flowing through the heater core, this may be caused by a couple of things: first, there might be a leak in the heater core, but usually antifreeze will be leaking into the heater core housing and will be visible, or there might not be enough antifreeze in the vehicles's radiator, or the water pump might be damaged and not circulating coolant. hope this helps and good luck!
