If you smell antifreeze, there must be a leak somewhere. Have the cooling system pressure tested.
Some people say that the smell of hot antifreeze smells like mold. It could be possible you are smelling the antifreeze from the engine.

An antifreeze smell inside the car typically indicates a coolant leak, which can occur due to a damaged radiator, worn hoses, or a faulty water pump. When coolant leaks, it can evaporate and produce a sweet, distinctive odor. Additionally, a malfunctioning heater core can also lead to coolant entering the cabin, causing the smell. It's essential to address any leaks promptly to prevent engine overheating and potential damage.
If you can smell it, it is leaking. Have it pressure tested by a professional.
You have a coolant leak.
Could be a few things. Does it leak antifreeze? if so, fix the part that leaks. If not, you could have coolant mixing with oil inside the engine, which burns it. check your spark plugs. If they are white, you are probably burning antifreeze - fix immediately. your exhaust will smell "sweet" as well if you are burning antifreeze.
If your going through coolant then you have an internal head gasket leak you smell coolant because its getting into cylinder and burning
if you smell it inside, it's the heater core it has a leak.
Your gaskets are leaking and you are leaking antifreeze inside the manifold. Same thing happened to me on my silhouette and cutlass. The problem is the orange anti-freeze eats the gaskets. Will cost $2,000-to-$3,000 to fix. Sorry!
It probably has a leak, possibly from the heater core.
