Why is a Radiator Overflow Tank an essential part of your car? 

Maintains Coolant Level: The radiator overflow tank, also called a coolant reservoir, stores excess coolant when the engine heats up. As the engine cools, the coolant contracts, and the reservoir supplies the radiator with the coolant it needs. This prevents the radiator from being overfilled when cold, which could lead to coolant spewing out when it expands.
