Is it really white and not light gray? What does it smell like?
Gray is burning oil. White could be condensation in the mufflers.
also it could be a broken piston or worn piston rings
replace the heater core
If it is white "smoke" then it is probably not smoke at all but only water vapour that is being cooled as it enters the cold air outside the house. It is nothing to worry about as long the heating system is working normally and also as long as you are having the heating system serviced every year by a licensed HVAC (Heating, Ventilation and Air Conditioning) engineer.Black or blue smoke coming out is another matter altogether and could indicate a dangerous fault in the system. If you see that kind of smoke coming out it is time to call a licensed HVAC engineer to inspect the system and advise you what should be done.
this kind of thing happens in my durango when i have the ac on and its humid inside the car.
The smoke is actually ice that freezes in the air
There are 3 different distinct colors of smoke coming form and engine. Eaqh one has a different meaning. White Smoke === Coolant leaking into the combustion chamber. Black Smoke === Fuel/Air mixture too rich. Blue Smoke === Oil burning.
It is NOT smoke, it is steam. It is your warm breath freezing in the cold winter air.
White smoke = Coolant entering the combustion chamber, normally caused by a blown head gasket. Black smoke = Overly rich fuel/air mixture Blue smoke = Oil burning, normally caused by worn rings.
Blue smoke = Burning oil Black Smoke = Overly rich fuel/air mixture White Smoke = Coolant entering the combustion chamberBlue smoke = Burning oil Black Smoke = Overly rich fuel/air mixture White Smoke = Coolant entering the combustion chamber
White smoke coming from the air vents when you turn off the cooling effect of your car's AC system is typically caused by condensation build-up within the system. When you turn off the AC, the cold air stops flowing through the vents, causing the moisture in the system to evaporate and be released as white smoke. This is a normal occurrence and is not usually a cause for concern. However, if the smoke persists or is accompanied by unusual odors or sounds, it may indicate a problem with the AC system that requires further inspection by a professional mechanic.
hurts it bye carbon coming uot and poisoning the air
Your breath as it is warmer than air around you will look like smoke
A very cold ice cube may appear to smoke, but actually what you are seeing is water vapor. The air around the ice cube is cooled by the cold ice cube, and when it cools, water vapor in the air condenses into fog.
