We observed in one of my neighbour new bought car that when start it in the morning,white smoke and water comes out from the exchaust after a while it will then stop,kindly advise what could be the causes?

Mr man, you should be worried if your car engine doesn't cough out water mostly in the morning. It is noticeable cause the exhaust is quite cold in the morning, even in hot afternoon, it happens too. What am trying to tell you is; if a vehicle engine is in good conditions, it will definitely cough out water. And the white smoke, that's how it is in the morning until the engine attained it operating heat temperature.

Also, white smoke and water from your exhaust indicates that your engine is sound. I mean very sound. Go and praise GOD tomorrow for it
