Why is my car blowing white smoke? That question startles a lot of people. This is because most people need their car to continue their lives smoothly. Most people rely on it to get to and forth from work. If your car is blowing white smoke than there is a 90 percent chance that water or antifreeze is burning.
In most cases the white smoke that is coming out of the car is from the radiator. This can happen if you have a cracked gasket that separates the motor oil from the liquid powered by the water pump. However, when this happens you will notice that there will be a time where there is an abnormal amount of white smoke at one time. After that, there will be a reasonably low amount of white smoke blowing from your car. The only way to fix this is expensive repairs at an auto shop. You can drive your car like this for some time if you make sure that the oil and coolant levels never drop below a certain amount, but you will eventually have rust to form in your engine.
If your car is blowing white smoke on a regular basis then you may have a different problem. The design of your car may be allowing your exhaust to trap water through condensation. This can happen in short trips and can be amplified by cold weather. When the hot exhaust cools quickly from a short ride you will have the same effect as leaving a cold water bottle in a warm room. The only difference is that the temperatures are on opposite sides. The cold air is all the air on the outside of the exhaust, and the warm airs that would represent the room temperature are inside the exhaust. Therefore, you will get a lot of water formation on the inside of the entire exhaust system. If you are trying to avoid this them you could simply warm your car up before you drive if you know that you are making a short trip. If you are going for a trip longer than 15 minutes then your exhaust should have heated up enough to negate the condensation effect.
