Thermostat: Testing and Inspection
THERMOSTAT INSPECTION
1. Remove the water thermostat.
2. Check the water thermostat for seating. Hold the water thermostat up to a lighted background. Leakage of light around the thermostat valve at
room temperature indicates that a new water thermostat should be installed. Some water thermostats have a small leakage notch atone location on
the perimeter of the thermostat valve, which is considered normal.
3. Immerse the water thermostat in a boiling antifreeze and water mixture.
