2006 BMW X3 Question: smell in the coolant system
Turn your A/C on and after a few minutes look under the front of your car. Look for water coming out of the heater box drain, should be on the firewall near the passenger side or center of the car. If no water starts to drip the drain is probably plugged and water is backing up in the case. Then when the fan is on it is blowing the smell of the stagnet water into your car. You will need to unplug the drain and go to local auto parts store get a can of air vent cleaner and follow the directions. - torque wrench
