A small leak in a head gasket. When the engine is hot the head expands and the leak opens up. When the cooling fan comes on it removes some of the heat and the leak closes back up. This will not last, the leak will get bigger and leak all the time.
white smoke is coming from my exhaust why?
If you are getting exhaust smoke coming out of the radiator overflow, you need to replace the head gasket that seals the cylinder from the cylinder cap where your coolant runs through to cool the engine.
If the smoke is coming from the electric fan itself, then it needs replacing. It could be the smoke is steam that the fan is drawing from the radiator, and you have a coolant leak at the radiator.
the smoke that comes out of a exhaust pipe is supposed to be white
If you see smoke coming from under the hood of your vehicle this indicates a serious problem. Your car is overheating, this could be because of low coolant in the radiator or another problem with the radiator.
NO
It is buring oil this is a wrong answer whe engine burn oil to the exhaust smoke is a heavy white smoke no black
That smoke is steam. You have a leak in the radiator or a hose. Take it to a mechanic.
You may have bad head gaskets when,you are losing engine coolant and you don't see any leaks.you see a white smoke (steam) coming from the exhaust pipe.you have a sweet smell coming from the exhaust pipe.you see air bubbles in the radiator coolant with the radiator cap off and engine running.
yes.
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
Car maintenance is very important for a smooth ride. When there is white smoke coming out of the exhaust, it is usually an indication of water in the engine.
