[DeTomaso] Radiator Caps

[michael@michaelshortt.com]

Every pound of pressure raises the boiling point of water 3 degrees. if
your system is designed for 10 psi and the cap is capable of holding that
you have increased the boiling point 30 degrees.

So a 16 psi cap could stand a temp of  260 degrees, whereas 22 psi could
handle up to  278 degrees.

I guess none of us want temps anywhere near 260 anyway, so perhaps the
lower rated cap is sufficient.

The next point then becomes, if the cap fails to release the pressure, then
something else might, like a hose, gasket, etc.
