[Healeys] thermostat discussion

[Oudesluys]

Hmm,
Not so sure about this. The temperature is regulated by the thermostat, 
more or less. If more heat is developped it will open further to allow 
more cooling to drop the temperature to the set level.
The reading also depends on where the sensor is placed. In the cilinder 
head, intake manifold, thermostat housing, top of radiator etc.
Changing over the thermostats may cast some light here? Just to see what 
happens.
