How do you know? easy drive normal route and after 5 miles or so turn car off then turn key to on without cranking it.
That's not quite a valid test of what you're looking for.

It's normal for coolant temperature at the sensor (and in the water jacket generally) to spike when you shut off the engine, because the coolant is still absorbing heat from the engine, but it's not circulating through the radiator.

I can hear if my Firefly/Metro's fan is running during low speed (city) driving. And the fan never comes on. Yet it will come on after I shut off the engine and turn the key back to "ON" as you describe.

EDIT: I'm not saying you don't have a point! If you can't hear your car's fan while driving, it may not be good.

But a better approach would be to monitor your fan status by installing an LED indicator so you know when it's on.
