Place a thread so that it is caught in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.
(The example shows the thermostat.)
The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
Continue heating. Check the full-open lift amount.
After checking the full-open lift amount, lower the water tempera-
ture and check the valve closing temperature.
If the measured value is out of the standard value or unusual valve
seating condition is found, replace water inlet and thermostat
assembly.
INSPECTION AFTER INSTALLATION
Check for engine coolant leaks using suitable tools. Refer to CO-58, "Inspection".
