I would say you better add more coolant
It's steam from boiling coolant (or water) coming out of the overflow hose connected to the top of the radiator just below the level of the cap.
internal engine leak is possible, smell your exhaust is it sweet? is there moisture coming out of your tail pipe? is there water in your oil? it is also possible for your engine to run so hot that coolant evaporates as steam through the overflow tube into the fill tank, keep it full
If there is no leak visible so you can see antifreeze under the parked car, you probably have a head gasket going bad. You may have some signs of steam in your exhaust, or at least a sweet smell coming from the exhaust. You should have a compression test done on your engine. That is exactly what the overflow reservoir is for. When the engine is hot, excess coolant goes into the overflow tank, as the engine cools,it draws coolant back into the radiator.
built up heat coming out engine breather tubes on the motor!
Steam may be coming out the air conditioning unit if the engine is overheating. The best thing to do would be to shut the vents before any hazardous fumes begin to come out.
if it's coming from the tail pipe or an exhaust leak, it means you have a blown head gasket!
A steam engine is an external combustion engine. As the steam engine combusts outside of the engine itself.
A rotary steam engine was a fire engine basically
Steam is created in a steam engine by heating water in a boiler until it turns into steam. The steam then builds up pressure, which is used to power the engine and drive machinery.
the steam engine was improved in 1769.
