Removal and Installation

REMOVAL

1. Drain engine coolant from radiator. Refer to CO-37, "Draining".

CAUTION:
• Perform this step when engine is cold.

2. Remove air duct (inlet) and air ducts. Refer to EM-161, "Removal and Installation".

3. Disconnect radiator hose (upper). Refer to CO-42, "Exploded View".

4. Disconnect harness connector from engine coolant temperature sensor.

5. Remove water hoses and heater hoses.

6. Remove water outlet.

7. Remove engine coolant temperature sensor from water outlet, if necessary.

INSTALLATION

Installation is the reverse order of removal.

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-54, "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-37, "Inspection".

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