The expansion tank, commonly known as the antifreeze reservoir or water tank, is an important component of the cooling system. It stores the coolant discharged from the engine cooling system. When the coolant temperature is high, it expands in the radiator, or when there is excess coolant, the pressure increases and releases. After the engine cools down, the excess coolant flows back to the radiator from the vehicle's expansion tank.
