[Healeys] high altitude driving

[Oudesluys]

Forgot to mention to fit a higher pressure radiator cap as on high 
altitudes you will have reach the boiling point at a lower temperature 
than usual as the pressure will drop (radiator cap works on over 
pressure, not absolute pressure).
At 10.000ft you have a drop in atmospheric pressure from ca. 14,7psi at 
sea level to ca. 10psi, so if you use a 7psi radiator cap go to a 12psi 
rad cap. and check the condition of your hoses and radiator. They need 
to be in good order if you want to avoid a blown hose or radiator.
