Subject:      fan switch or sensor, a busdepot question

Mathew, mathew, mathew,
       yee of so little faith, if I did not know
better I would say yeh name is thomas.
    The after shutdown cooling fan action is about
cooling the radiator and coolant in the radiator not
the motor.   By this air flow, overboiling is
prevented.   It's the old pv equals nrt equation.   If
T temperature  goes up than pressure and or volume
goes up and coolant goes pissing our the back blue cap
into the overflow everytime you shut off a hot engine.

     Which brings me  to my busdepot question.
Busdepot sells a sensor switch which is a lower
temperature switch for the two speed radiator fan.
Does anyone know if it works better?
          thanks gary

yes, but it is stupid. On the a2's the fan will pull
air through the
radiator and over the engine to cool it. Whereas the
vanagon will pull
air over the radiator but that air doesn't get over
the engine nor does
the coolant cycle. What is needed is a small electric
pump that will
cycle coolant while the after-run coolant fan is on.
Unless there is
enough thermo-syphoning going on to make it work.
Doubt it.
