[Healeys] Radiator cap thermostat combinations

[warthodson at aol.com]

Just to be clear, a 10 Lb cap won't reduce "overheating". It just raises the
temperature (pressure) at which the radiator cap will release the pressure &
the radiator will boil over.

John,

In the thread following your question, nobody appears to have
mentioned that the later BJ7s and all of the BJ8s ran a 10 lb
long-neck radiator cap.  All of the others up to that time ran a
long-neck 7 lb cap.

Some years back a friend had major overheating problems in a BJ8.  I
checked the cap and discovered a short-reach 7 lb cap had been fitted.
I replaced it with the correct one and the problem was immediately
solved.

I am surprised that even today many owners do not seem to be aware of
this change-over, or that there are short-neck and long-neck pressure
caps.
