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.

A radiator cap comprising: a) a handle portion having an engaging means configured to engage a rim surrounding an opening of a radiator for securing the radiator cap to the radiator; b) a gasket portion disposed below the handle portion and depending from the inner surface of the handle portion having a first gasket positioned adjacent to the handle portion and a second gasket spaced axially downward from the first gasket by a predetermined distance, wherein the gasket portion cooperates with the handle portion such that when the radiator cap is placed onto the rim surrounding the opening of the radiator, the first and second gaskets seat against different parts of upper and lower rims surrounding the opening of the radiator thereby providing a seal; and c) sacrificial anode for inhibiting erosion of the radiator and engine components, the sacrificial anode depending from an interior surface of the radiator cap and configured to extend from the interior surface of the radiator cap coaxial with and into the radiator, the sacrificial anode being only below the gasket portion second gasket such that the end of the sacrificial anode distal from the interior surface of the radiator cap is at least partially immersed in fluid contained in the radiator, whereby the radiator cap an be periodically removed from the radiator in order to monitor the state of the sacrificial anode.
