* Coolant leak. If the car has been sitting for a while, the coolant may have evaporated or leaked out. This can cause the engine to overheat, which in turn can cause white smoke to come out of the tailpipe.
* Condensation. When a car sits for a long time, moisture can build up in the exhaust system. This moisture can turn into steam when the engine is started, which can also cause white smoke to come out of the tailpipe.
* Oil leak. If the car has an oil leak, the oil can burn off and create white smoke. This is often accompanied by a burning smell.
If you see white smoke coming out of your tailpipe, it's important to take your car to a mechanic to have it checked out. It could be a sign of a serious problem.
Here are some additional tips for preventing white smoke from coming out of your tailpipe:
* Make sure the car has plenty of coolant.
* Check the oil level regularly and add oil if necessary.
* Have the car serviced regularly.
* Don't let the car sit for long periods of time without starting it.
By following these tips, you can help keep your car in good condition and avoid the problem of white smoke coming out of the tailpipe.
