The case for sacrificial anodes in your cooling system

I want to check what's in it. If I had to guess, I'd say that it pretty much stays in solution and combines with some component of the anti-freeze. When I was in high school, the only subject that caused me any trouble at all was organic chemistry, so I'm just guessing.

All of this happened in less than a years elapsed time and less than 2000 miles.

Tubman, I have to wonder what else might be going on in your cooling system.
I'd installed NOS heads on my '36 roadster about two years ago. At that time, I'd installed a diode in the same fashion as you.
Because of your post, I'd inspected mine and found it to be nearly as new. I had to look very closely to see any type of corrasion upon it.
