INSPECTION AFTER REMOVAL
Thermostat
Place a string so that it is caught in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.
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 temper-
ature and check the valve closing temperature.
Standard values
If out of the standard, replace thermostat.
INSTALLATION
Note the following, and install in the reverse order of removal.
Install the thermostat with the whole circumference of each
flange part fit securely inside the rubber ring.
Install the thermostat with the jiggle valve facing upwards.
INSPECTION AFTER INSTALLATION
Check for leaks of engine coolant using the radiator cap tester adapter (special service tool:
EG17650301) and the radiator cap tester (commercial service tool). Refer to CO-32, "
CHECKING RADIA-
TOR SYSTEM FOR LEAKS" .
Start and warm up engine. Visually check if there is no leaks of engine coolant.
