If I every use anything that's chemical to flush my radiator, I'll surely make sure it hits only that... i.e. not to back flush loosened junk from it into the engine.. If I was to flush the water jacket. I'd remove the radiator so I'd not flush engine rust etc. into the radiator... Seems to me keep the two systems separator when flushing... 2 cents from a newbie..
