Abstract

A radiator cap having an integral sacrificial anode inhibits corrosion of metal within the radiator. The radiator cap is placed on the opening of the radiator thereby immersing the sacrificial anode in coolant fluid contained within the radiator. The sacrificial anode is preferentially oxidized, thus providing cathodic protection. The radiator cap is easily removable and allows efficient monitoring of the condition of the sacrificial anode. When the sacrificial anode is depleted it is easily replaced to provide a fresh sacrificial anode.
