Over here, it boils at 100 degrees.  Over there, it boils at 212 degrees.

There used to be places (perhaps there still are) where it boils at
80 degrees.

Anyway - cooling systems are pressurised to a limit (on Audis) of about
1.4 bar.  The cap contains a safety valve - in my own experience, this
operates once and once only.  After an event, it has to be discarded.

It's _supposed_ to survive and reset itself - they never do.
