Lawson, the overflow tube goes to the bottom of a recovery tank. If the cooling system is properly sealed, coolant is pushed out the overflow tube and discharged into the bottom of the overflow bottle. As the system cools, coolant is drawn back into the radiator. Since the water level rises and falls in the recovery bottle, you can see by the decreased level in the recovery bottle if there has been a loss. Of course, if there is a leak in the system air will be drawn back in instead of water. Diligence is required.
