>With the deep knowledge on this list I am sure someone knows the answer to
this question about cooling fans.
When the cooling fan is mounted to the engine via either direct attachment
to the crank or through a fan belt, and activated through a viscous
coupling, what it the mechanism by which the viscous coupling is activated?
Is it based on some temperature switch in the coolant, or a temperature
switch in the viscous coupling fluid, or a pressure switch in the viscous
coupling fluid, or through some other means?
Thanks in advance for any insights.

Thank god, a technical question!
The viscous clutch itself is sensitive to the temperature of the air
passing by and responds accordingly.
