5 minutes is way too long without coolant; a sure recipe for a cracked head
or worse.

You might be able to get that much if you find a way to fill it with water
and top it up when it starts boiling.  But even that is a risk, IMO, both to
the engine and you.  It may eject boiling water just as you look at it and a
face full of boiling water can ruin your whole day!
