Radiator anode kit. Anyone try them?

Just found these on another site and it sounds like a good idea as they have been used on boats for a long time.

Found them on the web a kit of the brass plug and an anode for about $10.00

Zinc Anode Kit for Aluminum Radiators

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.

I'm sorry that I missed your post when it was new claymore. I don't know that this product is actually necessary on a new (or new-er) Honda, but for sure this could not hurt anything. Corrosion that might start to attack the aluminum cooling system parts would attack the zinc anode FIRST, and while doing that would protect the aluminum from attack. Since you would have to remove the anode whenever you would drain the radiator for maintenance, if you see corrosion on the anode, just replace it with a new one to continue the protection.

While I am under the front of my GE8 in the next couple of days, I will check to see what size the drain petcock on the radiator is. If it is 1/4" NPT (probably is), I will order two of the anodes. That should set me up for corrosion protection for the next 6 years or so.

Good find!!

Found this on a ford big block site and they were using these in the new aluminum blocks as the blocks are BIG BUCKS and some people have found the aluminum being attacked. so I figured if it's good enough for them it must be good for our aluminum engines too.

And they are cheap, the only very small down side if you can call it that is needing a wrench to drain the coolant but they also have a radiator cap with one built in that solves that problem.

Hello Gentlemen,

What were the results? Any corrosion found on the zinc anode?

Thank you for your time. :-)

Never did buy them but on another site the users did report that they had shrunk a bit from getting eaten away.
