I thought I would find some issues with you here, but your points are not at
all bad.

"Electrolysis" is a catch-all word that people use instead of
electrochemical explanations.

It is not an all inclusive term.

Galvanic corrosion often occurs when metals of two unlike redox potentials
are
connected with an electrolyte as the external current path.. Basically what
you said,
but a little more detailed.

Electrolysis may also take place when corrosion currents occur from sources
other
than galvanic contacts.

Corrosion inhibitors CAN reduce corrosion enormously by modifying the
surface
matrix on a metal, in contact with an electrolyte.

Triple distilled water (or GOOD deionized water) can be a wise choice
instead of
tap water that may be laden with a plethora of minerals.

Aluminum is a strange one. When properly anodized, it can be relatively
corrosion
resistant. When that film is broken, aluminum is not worth a darn as a
corrosion
resistant metal.

Worthwhile post, Jim

thank you. difficult to condense major scientific principles into just
a few paragraphs.

Not being a chemist, I solved this quandary by simply following the
specific directives of the engineers that designed my engine and/or its OEM
fluids. I decided that they are quite likely to know best exactly what will
prevent my engine's cooling system from corroding. And you know what? The
advice I've followed has been spot-on.
