4.1. Set a multimeter to 200 ohms.
4.2. Use an alligator clip to connect the black (–) probe of the multimeter to the frame (ground).
4.3. Use an alligator clip to connect the red (+) probe of the multimeter to the white wire terminal.
4.4. The multimeter should indicate an over limit (no continuity) at room temperature. If the multimeter indicates
continuity at room temperature, replace the thermostat switch. See Thermostat Switch Removal on
page 14-18.
4.5. Leave the black (–) probe of the multimeter connected to the frame (ground). Use an alligator clip to
connect the red (+) probe of the multimeter to the black wire terminal.
4.6. The multimeter should indicate an over limit (no continuity) at room temperature. If the multimeter indicates
continuity at room temperature, replace the thermostat switch. See Thermostat Switch Removal on
page 14-18.

5. Unscrew the thermostat switch from the engine block. See preceding WARNING.
6. Test the fan control thermostat switch.
6.1. Place the thermostat switch in a kitchen pot as shown (Figure 12-18, Page 12-22) .
6.2. Set a multimeter to 200 ohms.
6.3. Use an alligator clip to connect the black (–) probe to the thermostat switch housing.
6.4. Use an alligator clip to connect the red (+) probe to the white wire terminal.
6.5. The multimeter should indicate an over limit (no continuity) at room temperature. If the multimeter indicates
continuity at room temperature, replace the thermostat switch. See Thermostat Switch Removal on
page 14-18.
6.6. Fill the kitchen pot with water so that approximately half of the thermostat housing is submerged as shown
(Figure 12-18, Page 12-22) .
6.7. Place the kitchen pot on a stove and bring the water to a boil. See following WARNING.
WARNING
• Hot! Do not touch hot surfaces or boiling water. Contact with hot surfaces or boiling water will result
in severe burns. Allow hot surfaces to cool adequately before touching them.
6.8. The multimeter should indicate continuity between the housing and the white wire when the thermostat
switch is submerged in boiling water. If the multimeter does not indicate continuity, the thermostat switch
has failed and must be replaced. Discard the failed thermostat switch and install a new one.
See
Thermostat Switch Installation on page 14-19.
6.9. Turn off the stove. See following WARNING.
