Why does my car smell like coolant but no leak?
As coolant drips out, it could hit a hot part of your engine, begin to evaporate, and create a pungent odor that you’ll be able to detect. The heater core of your vehicle contains an antifreeze and water mixture, and it uses this mixture to regulate the temperature of the air inside your car.

It could be coming from a radiator or heater hose, a failed intake manifold gasket or cylinder head. It might be coming from a leaky radiator cap or the radiator itself, especially if you smell it outside the car.
What does it mean when you smell antifreeze through your vents?
Coolant/antifreeze leaking out through the heater core means that the overall coolant level in the system will be low and the engine is in danger of overheating – which is the most common cause of mechanical breakdown.
Can you lose antifreeze without a leak?

How do you know if your internal coolant is leaking?
If you suspect an internal coolant leak, allow the radiator to cool, take off the cap, and look for signs of oil or frothy bubbles in the radiator or header tank. With the engine running, smell the coolant itself – if there is a whiff of exhaust gas , the cylinder-head gasket may be leaking.
