The steam disperses inside the engine compartment. I understand that my system is not completely sealed and was like that from the factory. Close. The reserve is where you fill it at and it takes the coolant directly to the radiator. If the coolant you have is weak (too much water), the boiling point will be reduced.

That will allow coolant to evaporate via the overflow. Leaks can come from the overflow tank, the radiator, the water pump, coolant hoses and elsewhere.
