The coolant recovery tank is part of a sealed cooling system. When hot coolant expands and exceeds the capacity of the radiator, the excess coolant flows into the recovery tank. When the engine cools, coolant is drawn by vacuum back into the radiator.
Most of the coolant that is forced into the expansion tank returns to the radiator naturally after a few hours or when the engine is cold. If you had no expansion tank on your car, then the coolant that was released under pressure would spill out onto the road.hen the pressure builds to a high enough point, the radiatior cap allows that pressure to escape into the coolant reservoir through a small black rubber tube, called an overflow tube connected by the neck of the radiator to the expansion tank.
