Coolant leak
The white smoke could be caused by a coolant leak. Coolant is a liquid that helps to keep your car's engine cool. If there is a leak in the coolant system, coolant can get into the cylinders and burn off, creating white smoke.
Blown head gasket
A blown head gasket can also cause white smoke to come out the tailpipe. A head gasket is a seal that sits between the cylinder head and the engine block. If the head gasket is blown, coolant can leak into the cylinders and burn off, creating white smoke.
Cracked cylinder head
A cracked cylinder head can also cause white smoke to come out the tailpipe. A cracked cylinder head can allow coolant to leak into the cylinders and burn off, creating white smoke.
Other possible causes
In some cases, white smoke coming out the tailpipe can be caused by other factors, such as:
* A faulty PCV valve
* A clogged catalytic converter
* A rich fuel mixture
What to do
If you are seeing white smoke coming out the tailpipe of your 1999 Chevy Malibu, it is important to have the car inspected by a qualified mechanic as soon as possible. The mechanic will be able to diagnose the cause of the smoke and recommend the necessary repairs.
If the smoke is caused by a coolant leak, the mechanic will need to find the leak and fix it. If the smoke is caused by a blown head gasket or a cracked cylinder head, the engine will need to be rebuilt or replaced.
Here are some tips for preventing coolant leaks:
* Check the coolant level regularly and add coolant as needed.
* Inspect the coolant hoses and replace them if they are cracked or damaged.
* Have the coolant system pressure tested regularly to check for leaks.
By following these tips, you can help prevent coolant leaks and keep your car running smoothly.
