Regardless of color, smoke is an anomaly and indicates that something is wrong with your vehicle.

Note that your car is smoking This is not normal, most likely during the winter season due to condensation that forms in the car, but besides this possibility, thick white smoke is a sign of a serious problem that needs to be addressed immediately. Ignore the smoke, worst case scenario may cause the engine to burn out..

To understand why your car smokes and why it's white, you need to understand the basics of how a car works.

What is exhaust emissions?

Exhaust gases coming out of a car's tailpipe are direct by-products of the combustion process that takes place in the engine. The spark ignites the mixture of air and air and the resulting gases are directed through the exhaust system. They pass through the catalytic converter to reduce harmful emissions and through the muffler to reduce noise.

What are typical exhaust emissions?

Under normal conditions, you probably won't see exhaust gases coming out of the tailpipe. Sometimes you can see a light white color which is just water vapour. It is important to understand that this is very different from thick white smoke.

Why does white smoke come out of the exhaust pipe when starting a car?

When you see white, black, or blue smoke coming out of the exhaust, the car sends out a distress call for help. White smoke from the exhaust pipe indicates that fuel or water has accidentally entered the combustion chamber. When it burns inside the block, thick white smoke comes out of the exhaust pipe.

What causes coolant or water to enter the combustion chamber?

Thick white smoke coming out of the exhaust pipe usually indicates a burnt cylinder head gasket, a cracked cylinder head, or a cracked cylinder block. Cracks and bad joints allow fluid to get in where it shouldn't, and that's where the problems start.

What to do if you see white smoke coming out of the exhaust pipe?

The most important thing is that You must not continue to drive. If the engine has a defect or a cracked gasket, it can lead to further fouling or overheating, which is essentially engine failure.

If you need more proof that your car has a coolant leak inside the block, you have two options. You can check the coolant level first, if you notice the level is low and you don't see coolant leaks anywhere else, this confirms the theory that you have a leak or crack in the cylinder head gasket. Alternatively, you can purchase a cylinder block leak detection kit that uses chemicals to detect coolant contamination.

Unfortunately, once it's determined that a head gasket is blown, a cylinder head is punctured, or an engine block is broken, it's time for a major overhaul. The only way to confirm these problems is to remove half of the engine and get to the block.

Since this is one of the most important car repairs, it is not recommended to do it without the knowledge and without the right tools for this task at home, ideally take your car to a trusted experienced mechanic who will analyze whether it is worth it or not. No repair, depends on car cost.
