Inspection

INSPECTION AFTER REMOVAL

Water Control Valve

• Place a thread (A) so that it is caught in the valves of water control valve (1). Immerse fully in a container (B) 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 continuous valve lifting toward maximum valve lift.

NOTE

:
The maximum valve lift amount standard temperature for water control valve is the reference value.

• After checking the maximum valve lift amount, lower the water temperature and check the valve closing temperature.

Standard: Refer to CO-29, "Water Control Valve".

• If out of the standard, replace water control valve.

INSPECTION AFTER INSTALLATION

• Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the radiator cap tester (commercial service tool). Refer to CO-11, "Inspection".

• Start and warm up the engine. Check visually that there is no leakage of engine coolant.
