Unless your coolant is very low all of them are below the level of the
coolant, which is why they weep when they start corroding through or there
is a bad edge seal, but I'm not saying they would pop in a freeze.  They are
not machining access holes either, just a side-effect of the casting process
as you say, which is why they are known as 'core plugs' in my experience,
the 'core' being the inner part of the casting mould.
