[Healeys] Texas cooler

[John Harper]

Not from the impeller but it is the seal that is lifted off the casting 
against the spring pressure.

I think that you will find that very few British cars in the early 1950s 
had pressurised cooling systems. In the latter part of the 1950s many 
manufactures started to fit pressurised caps but only 4, 7 or 10 p.s.i. 
I have found one on Bedford Viva van at 13 p.s.i. in an AC catalogue but 
that specifically only applies when a special radiator is fitted.
