Hey everyone, new member here! Bought my car about a month ago and am now noticing a coolant smell when I turn my heater on in the cab. Took it in to the dealer and they find nothing wrong related to the coolant system (did they even check?) They say it might be the stuff they spray on the engine when it's new, burning off. I doubt that since my car has 1300 miles! Does anyone have any idea what this is??
