  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 a new water thermostat should be installed. Some water thermostats have a small leakage notch at one location on the perimeter of the thermostat valve, which is considered normal.
  3. Immerse the water thermostat in a boiling antifreeze and water mixture.
  4. See the General Specifications chart for water thermostat opening temperatures.
