AnswerCheck your heater core, do you smell antifreeze at all?no
Heater core leaking.
The smell of antifreeze is very strong and distinct, it does not take much of a leak to smell it. The radiator could still be full and have a small leak. I would check for antifreeze dripping onto the exhaust or on the engine block because when it is hot the smell is much more noticeable from the fumes.
i believe the heater core is leaking, a small pin hole leak can generate a lot of smell.
If you smell antifreeze, there must be a leak somewhere. Have the cooling system pressure tested.
It probably has a leak, possibly from the heater core.
Probably - your head gasket is blown. Antifreeze will be coming out of the tail (exhaust) pipe.
Most of the time it is caused by a hole in the heater core, do you smell a sweet smell? The sweet smell would be the antifreeze.
heater core possibly plugged and leaking
Only reason would be that the heater core is leaking.
Does it smell like burning antifreeze? Usally it means that the heater-core is going bad. If you do not service it it can be a lot worse. You will end up with Anitfreeze all over you passenger side floor board.
The "antifreeze smell out the AC vents" would mean only one thing, you have a small leak in the heater core.
