It has a leak in the Cooling System Somewhere, It might have a cracked Head or a Blown gasket
Have you spilt some on the radiator?
Some people say that the smell of hot antifreeze smells like mold. It could be possible you are smelling the antifreeze from the engine.
most likely you need to replace te heater core.generally i if the leak is on engine you wont smell it in the car
It is possible that the heater core ( the device that heats the air inside the car) is leaking. It is connected to the engine cooling system.
The only reason is a leak. Usually small. The place to start is: If it smells like oil or antifreeze ...
If you mean "why", then the answer is that there is a leak in the heater core.
smell of antifreeze and no visable leaks usually indicates that the heater core needs replacing
Cuz it runs on diesel or your cat is shot, sorry bud.
if it smells like antifreeze inside the cockpit then your problem is the heatercore, since you can't see it.
I'm not a mechanic / technician but it sounds like your heater core is leaking Have you noticed if your engine coolant level is going down ?
your heater core is probably bad.
