Remove the thermostat (see Thermostat Removal).
Inspect the thermostat valve [A] at room temperature.

If the valve is open, replace the thermostat with a new one.

Thermostat Inspection

To check valve opening temperature, suspend the thermostat [A] in a container of water and raise the temperature of the water.

The thermostat must be completely submerged and must not touch the container sides or bottom. Suspend an accurate thermometer [B] in the water so that the heat sensitive portions [C] are located in almost the same depth.

It must not touch the container, either.

If the measurement is out of the specified range, replace the thermostat with a new one.
