What does the smoke smell like, oil, anti freeze, or burning rubber or brakes? If it is anti freeze, wondering if you have checked the coolant level in the resevoir and or radiator. Don't check radiator while hot, please. If the coolant is OK but still smells like anti freeze it may be your thermostat. If you are running it hot until it stops, you are doing it some major harm. Where exactly is the smoke coming from?
