INSPECTION <4A9, 4B10, 4B11-TURBO>



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 <4A9>
      82 ± 1.5°C <4B10>
      76.5 ± 1.5°C <4B11-Turbo>

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 <4A9, 4B10>
      90 °C <4B11-Turbo>
    Amount of valve lift:

      8 mm or more <4A9>
      8.5 mm or more <4B10, 4B11-Turbo>
