Anti freeze odor is overwhelming in the car, especially when the heater is run. I have had the car since it was new, and had the same problem after only a couple of months. The dealership fixed the issue by installing a new gasket, but the fix has lasted only a couple of years. My wife and I have been having a variety of respiratory illnesses recently, and I believe these fumes are a contributing factor.
