INSPECTION
PROCEDURE
1. INSPECT THERMOSTAT
HINT:
The valve opening temperature is inscribed on the thermostat.
|
(a) Immerse the thermostat in water, and then gradually heat the water. |
|
(b) Check that the valve of the thermostat opens at the specified temperature.
Standard valve opening temperature:
80 to 84°C (176 to 183°F)
If the valve does not open as specified, replace the thermostat.
|
(c) Check the valve lift. Standard valve lift: 10 mm (0.394 in.) or more at 95°C (203°F) If the valve lift is not as specified, replace the thermostat. |
|
(d) Check that the valve is fully closed when the thermostat is at a low temperature (below 77°C (171°F)).
If the valve is not fully closed, replace the thermostat.
