On the '91 200 20v the coolant pump and the fan should come on couple of
minutes after shutting off the engine, and both should shut off
automatically after a few minutes. Otherwise the pump should not be running
at all when the engine is running. Apparently it takes a couple of minutes
for the heat soak to build to the point that it trips the sensor.
I have installed an over-ride switch with a timer relay so that when things
are really hot I just flip the switch when I shut off the engine, and the
fan and pump come on immediately and go off after five minutes.
