Years ago, I cracked the passenger side head, on my '84 7 passenger, (a
story in itself) during a trip from Maine to Virginia.  I continued the
trip and the infusion of combustion gases into the coolant got worse.
Before starting home (1200 miles) I found that I could loosen the
radiator bleed screw and combustion gases (as well as some coolant)
would escape without overpressurizing the system and without overheating
the engine.  I could go 27 miles before the low coolant light would come
on at which time I could top up the coolant and proceed without having
to worry about an overheated engine.  Yeah, pulling over every 27 miles,
during the winter, wasn't fun but it allowed me to get home without
further damage where I could effect a proper repair at my leisure.

Granted, the light didn't indicate a "Sudden" coolant loss, but I found
it most useful just the same.
