That's pretty much how I imagined it. I remember on my last car the coolant expansion tank had a lid you could open with a hose on the top. One end transferred coolant and the other was open to the atmosphere. I literally know nothing about automotive cooling and I'd rather not take "educated" guesses at where exactly this system becomes closed if ever.

Thats exactly what I was saying... lol.
The system is closed in the radiator cap. The spring in the cap has a certain amount of pressure. When the water pump is spinning it creates a vacuum/suction to pump through the block and return to radiator where heat dissipates. Should you become low, the pressure decreases, and pulls in fluid from the burp tank (reservoir).
Again, I'm not a mechanic, nor hvac guy, I know friends who are, and my college experience was only 1 semester of automotive engineering.
But I think we got a pretty good handle on it,
Lets go build a car now... lol
