DM,

I replied to this you should already have copy,

If not then in short there must still be a pressure relief  valve (old
style radiator cap)
in the cooling system at the highest point. The rest is in the other reply.
Just will not happen the way it is put above.
Unless you are nutty enough to leave out any pressure relief, should the
worst happen.
You would have to have a multiple catastrophic failure all at once.
You would need something like this to happen all at once.
Pressure relief failed, the water pump belt broke and the air flow to
the cooling system got blocked.
The chances of this happening at once approaches zero.
