INSPECTION


THERMOSTAT CHECK

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

    <134, 135> 82 ± 2 °C
    <3A9, 4A9> 87 ± 2 °C
    <4G1> 82 ± 1.5 °C

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
    Amount of valve lift:

      <Except for 4G1> 8 mm or more
      <4G1> 8.5 mm or more
