On a closed system with an overflow bottle, that the system should be filled to the top when it is at operating temperature. One of the advantages of this type of system is to reduce oxidation by eliminating all air from the system. Hence it then becomes a closed system. Why leave a head of air in the top of the radiator when you don't have to? Entrained air is sometimes difficult to get out of the system. The secret in the system lies in the overflow bottle. Coolant, due to excess heat from the engine bleeding heat through the water jackets, will expand H(ydrogen) and the O(xygen) molecules, thus increasing the total water volume's mass. This mass will bleed through the rad cap (valve) and end up in the overflow bottle which is vented to the atmosphere. When they mass is cooled due to the air flow through the radiator or turning off the engine, the rad cap will release it's thermo pressure and allow the valve to open and syphon the reserve coolant back into the water jackets, thus keeping a set amount of mass present in the cooling system. | On a closed system with an overflow bottle, that the system should be filled to the top when it is at operating temperature.
