[Healeys] thermostat discussion

[Alan Seigrist]

Kees -

I live in the hottest climate of anyone here.

If you are lucky enough to still have a factory radiator core (many
BN1s and BN2s will have em), rodding will do wonders to improve
cooling.  The trick is you have to also power flush the block and use
a thermostat with a wide diameter opening.
