Zinc Anode Kit:
Flex-a-lite has developed a new zinc anode kit part #32060 to be installed in the radiator as a replacement for the drain petcock in radiators that are equipped with a ¼" NPT bushing welded into the tank. Or it maybe installed in any ¼" NPT hole that is available in the cooling system.
For years Anodes have been used in Heavy Duty and Marine applications to protect the cooling systems and its many components from damage due to electrolysis or coolant additive failure/breakdown. In some cases other corrosive material used in manufacturing and remanufacturing of engine parts and components.
Flex-a-lite now brings this protection to you. Today's cars and trucks have many aluminum parts and parts made in combination with aluminum alloy. Aluminum parts may disintegrate from electrolysis in the cooling system. The introduction of the zinc anode will protect your cooling system from galvanic action "Eats" the zinc rather than your cooling system.
