You have a blown head gasket. Check the oil and antifreeze, they may have mixed. Have a mechanic pressure test your cooling system.
usually you will get antifreeze smell and steam inside coming from defrost
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.
you got a gas line leaking. get it checked soon
You have either a cracked heater core or bad heater hoses that are allowing antifreeze to enter into the vehicle............
Check both the heater core as well as the heater hoses for leaks...........
your vehicle may smell like antifreeze while driving because it is overheating
if you can smell antifreeze you need to replace the heater core in the vehicle
A small amount of antifreeze smell may be emitted from the radiator overflow. However if you smell antifreeze you need to make sure there isn't a leak. It may be something simple if you catch it early.
i believe the heater core is leaking, a small pin hole leak can generate a lot of smell.
If you smell antifreeze in the passenger compartment of your car your heater core is probably leaking. It's under the dash somewhere ( depends on the make and model ). Another symptom of a leaking heater core is moisture build up on the inside of the windshield when you run your defroster.
