[Healeys] BJ8 radiator cap issue

[Lou G]

I would try replacing the two caps and try again !

This is defying logic & thermodynamics. Congratulations!
Since in either case the temperature has not reached the atmospheric 
boiling
point (I.E. 212 at standard conditions) neither cap is having any affect 
on
the operating temp. As stated earlier, the pressure of the cap only 
affects
the boiling point, not the water temp. I would try changing the 
thermostat &
try the experiment again.

b" Both are long neck

b" Neck of radiator is original

b" Never checked. With 180B: thermostat it reads 180B:, with 160B:, it 
read
160B: (no longer use 160B:).

b" Original water temp gauge, NOS Smiths 180B: thermostat
