How does a coolant overflow reservoir work?

Once the coolant returns to the radiator, it is circulated through multiple chambers to cool down and repeat the process continuously. However, one fact about coolant is that it expands as it gets hotter. The coolant overflow reservoir is designed as a relief valve of sorts that stores extra coolant for the radiator.

Why is my radiator coolant overflow tank not working?

So, the radiator coolant overflow tank functions to serve this exact purpose. The excess fluid flows into the overflow tube and goes into the overflow tank. Once the driver parks the vehicle and turns off the engine, the heat dissipates which causes the coolant to not be as hot anymore.

Why does the coolant go into the overflow tank?

As the pressure causes the coolant to get higher than the radiator pressure cap, the excess coolant needs to be captured somewhere in order to prevent leakage. So, the radiator coolant overflow tank functions to serve this exact purpose. The excess fluid flows into the overflow tube and goes into the overflow tank.

Why would coolant overflow out of the tank?

The level in the reservoir will rise and fall as the coolant heats up and cools down. If the reservoir is filled too full, excess will blow out the overflow tube when the coolant heats and expands.
