I could have sworn the last Honda 4-cylinder I saw had the iron cylinders
sitting bare-naked in the coolant. They were cast as a siamesed block of
four, and were fully exposed all the way down until they got buried in the
aluminum at the bottom.

nah, the actual steel liners are real thin - maybe 3mm - and the rest of
the siamese quintuplets are the alloy casting they sit in. it's an
unusual arrangement for sure. if you're doing a gasket scrape, it's
easy enough to test what's where because the soft alloy bit can be
scratched by the blade, the steel bit not. i'll see if i can take a pic
next time i'm in a junk yard.

I don't know where you read this, but there isn't that much iron in a Civic
engine, not where the coolant can get to it. Maybe the cylinder walls, but
if they are rusted up you have serious problems.

I would flush the system. Use the owner's manual instructions, if you still
have it. Fill it with Honda Genuine Coolant. It only takes a gallon of
pre-mix, and there are too many different types of coolant out there, to
take chances.
