Doesn't this (increasing pressure from 7 lbs to 13 lbs) put additional strain on
the radiator... possibly promoting a leak?
On my 'other' car I went from a 13 lbs to a 7 lbs cap just because the rad is 20
years old and I thought that would help it last longer. Yes it (higher
pressure) raises the boiling point of the coolant but can't also be done by
changing the coolant mix if you don't need protection to -60° or whatever a
50/50 mix provides?
