When was the last time you checked your coolant for its voltage? That sounds just wrong but there is more to the story
Corrosion is the result of a difference in voltage between two dissimilar metals - ie, if you have cast iron on one side of the swimming pool and aluminum on the other, eventually, all the aluminum will swim across the pool and join the cast iron party on the other side. (Not really the way my engineering professor taught it, but in simpler forms, it's correct)
If you check the difference in voltage between two surfaces, you can get an indication of what's going on and a head's up if there is a problem beginning. Classic to this is the aluminum used in our engines and subject to the coolant in the system. You can check that coolant and learn if there is a corrosion issue going on and correct it before problems start.
