No I'm pretty sure that it closes because the water doesn't move in the
radiator till the engine gets warm and the temp gauge goes up. Then if
you watch the gauge as you drive it will suddenly go down a little and
then goes up again then down a bit less and then stabilizes. That tells
me that the thermostat is opening and closing to regulate the temp in
the engine as it should.
I will check the heater valve tomorrow and see if it is opening as it
should.

Another possibility is the theromstat might not be closing. If water
is circulating, it will take longer to warm up.
