You can test it with hot water to see when it opens. Check out the FSM or Haynes manual for instructions.

Yup, use a candy thermometer (or any kind of cooking thermometer that goes high enough. Put that and the thermostat in a pot of water and turn on the heat. Now you'll know the temperature that the thermostat opens.
If the water boils (212 degres F!) and the thermostat never opens, you got problems.
Good luck

For the cost of a thermostat, and the damage that can be done if it doesn't open, your better off buying a new one.

Looks like the same answers you got in the teamfc3s forum. Conspiracy or coincidence?
