A change in the colour of the smoke coming from the exhaust pipe of your car is a sure sign that there has been some kind of fault of varying severity. It could simply be due to an accumulation of condensation and may not have any negative implications. On the other hand, it might be an indication that the vehicle is breaking down, and there could be serious consequences if you don't act quickly. At OneHowTo.com we'll explain what white smoke from the car exhaust means.
If you see white smoke coming out of the car exhaust pipe in thin wisps, but it's only when you start the engine, then there's no need to worry. This is due to an accumulation of condensation that finds its way out through the exhaust pipe.
If the car has a diesel engine, lots of white smoke coming out of the exhaust when you start it up indicates that the fuel pump injection timing is off. You must bring your car to a mechanic to check this issue and, if necessary, fix the fault. You can also check your fuel pump injection timing yourself to know if this is the cause.
If white smoke continues to come out of your exhaust while the car is running, and not just when you start it, it may be leaking coolant which is then being burned. This problem is not very serious but you must go to a professional mechanic as soon as possible to fix the leak.
Your coolant may also have run out in which case you will need to stop the car immediately as it will be overheating. Check the levels of coolant to make sure this is the problem and follow these steps to know what to do if your car overheats.
