Why is my car overheating and steaming?
The most obvious sign of an overheating car is steam or smoke coming out from under your hood. The presence of steam usually means you have a coolant leak. The more steam the worse the leak. If it’s all of a sudden and a large burst of steam, a hose may have just blown, and your coolant could have entirely boiled off.
Why is steam coming out of my exhaust?
Depending on the outside temperature, condensation will build up inside of your car’s exhaust system and the heat heading through the pipes will create steam. Thick white exhaust smoke usually indicates a coolant leak, which could cause overheating and put your engine at a serious risk of damage.
What causes steam to come out of the exhaust system?
A small amount of water is produced as a normal bi product of the combustion process and until the exhaust system warms up the water evaporates and can be seen as steam. When an engine heats up under normal driving conditions the exhaust system will get hot as well.
What does white smoke and steam from exhaust mean?

What goes wrong? If white steam is accompanied by a sweet or pungent smell it means the engine is burning coolant.
What can cause a car engine to overheat?
Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss.
Is it normal to have smoke coming from the exhaust pipe?

Typically, once a vehicle starts producing smoke the pattern will continue until the engine is repaired. What color is the smoke? The color of the smoke will help determine what to look for when troubleshooting the problem.
