Abstract
A membrane for the end surface of a container for a corrosion inhibitor for engine coolant where the membrane is exposed to the coolant and corrodes when the corrosiveness of the coolant increases above a predetermined level. The membrane is formed of the same metal or alloy as the radiator and has a thin layer thereon of a second metal except for certain areas where the base metal is exposed so that in a corrosive environment, a galvanic cell is set up between the two metals to enhance the rate of corrosion of the membrane.
