Why is the car still emitting white smoke after warming up?
1 Answers
When white smoke comes out of the exhaust pipe after the car has warmed up, it could be water vapor. Details are as follows: 1. If you usually see white smoke coming from the car's exhaust pipe, it is actually a large amount of white water vapor being emitted, accompanied by unstable engine operation. Even after the engine has warmed up to normal operating temperature, a large amount of water vapor continues to be emitted. 2. The cause of this phenomenon is likely due to wear in the engine cylinder head gasket, creating a gap that allows a significant amount of coolant from the cooling system to enter the combustion chamber. Water that cannot burn turns into steam when heated and is directly expelled through the exhaust pipe. 3. Additionally, some cars emit white smoke due to encountering so-called 'unscrupulous gas stations,' where the fuel has been adulterated with water by illegal vendors. However, this situation usually results in sudden white smoke emission after a specific refueling, making it relatively easier to identify the cause. 4. If your car is already emitting white smoke, promptly inspect the engine block and cylinder head gasket for damage, and check the fuel tank for water accumulation. If you've just purchased a new car, be sure to carefully review the car's manual and strictly follow the manufacturer's guidelines for adding the correct grade of gasoline.
