After I changed the pump the temp always stayed rock steady.
A vice-grip chain wrench gets enough grip on the fan shaft to loosen it from the pump. And they are useful for other projects, too.

I appreciate the help. I'm going to replace the NAPA stat' with a Motorcraft part and pull and check the water pump.
Thanks again!

eds94areo what part of the country do you live in? If is a hot climate I recomend puting in a 2 row radiator from an explorer in it. I got a brand new one from Auto Zone for $180 bucks. Now in the Las Vegas summers I have a much staler temp control.
