Quite true. I've notice the same thing in my aluminum water pump body
and intake manifold. Here's a counter measures that was suggested to
me: Install a chunk of magnesium in the radiator or header tank as a
sacrificial anode, perhaps suspended by a stainless wire or chain so
that it can be easily checked and replaced. Anyone ever tried this?
