To test a closed thermostat:

1. Suspend the thermostat (A) in a container of water. Do not let the thermostat and the thermometer (B) touch the bottom of the hot container.

2. Heat the water, and check the temperature with a thermometer. Check the temperature when the thermostat first opens, and when it is fully open.

3. Measure the lift height of the thermostat when it is fully open.
