INSPECTION


THERMOSTAT CHECK

1.Immerse the thermostat in water, and heat the water while stirring. Check the thermostat valve opening temperature.

    Standard value:

      82 ± 2°C <6G7>
      76.5 ± 2°C <4M4>

2.Check that the amount of valve lift is at the standard value when the water is at the full-opening temperature.
note Measure the valve height when the thermostat is fully closed, and use this measurement to compare the valve height when the thermostat is fully open.
Standard value:

    Full-opening temperature:

      95 °C <6G7>
      90 °C <4M4>
    Amount of valve lift:

      10 mm or more <6G7, 4M41>
      8.5 mm or more <4M40>
