Where does the coolant go in an overflow tank?
If you look at just about any overflow reservoir (not an expansion tank), the hose from the radiator run off goes to the bottom of the tank (or dips down to the bottom of the tank from the lid). This puts the outlet in coolant when at proper level. This allows for excess pressure to vent to the reservoir as well as any coolant.
How much fluid is in the overflow tank?
The whole system yielded about 1.5 gallons of fluid drained. When replacing the coolant and burping the air, I filled the overflow tank to the full line, and proceeded to put the rest of the coolant through the radiator cap.
What happens if your radiator coolant tank cracks?

You should notice small puddles or drops of coolant on your garage floor or in your driveway. Note: Coolant is very harmful to dogs and cats.
Why is my 2004 Chevy tracker spitting coolant?
2004 Chevy Tracker started spitting coolant from the overflow tank. No overheating problems or leaks beforehand until now. Without any warning, most of the coolant had blown out of the overflow tank. After allowing it to cool for a couple of hours, I refilled the radiator and overflow tank to recommended levels.
Where does the coolant come from in an overflow tank?
The overflow tank is connected to an overflow tube that comes from the radiator. This tank provides extra storage space for coolant as it expands when the engine heats up. Without this extra overflow storage space, the coolant would expand and run out from the overflow tube and onto the ground.
How do you drain radiator coolant in Chevy Silverado?

What causes coolant to leak from the radiator?
The coolant reservoir collects the hot coolant for recycling back into the radiator once it has cooled down. If you are often adding more coolant to the reservoir, you might have a leak. You might see coolant leaking if the tank is cracked or damaged. If your vehicle leaks too much coolant, your engine can overheat.
