• Place a thread so that it is caught in the valve of the water control
valve. Immerse fully in a container filled with water. Heat while stir-
ring.
• The valve opening temperature is the temperature at which the
valve opens and the falls from the thread.
• Continue heating. Check the full-open lift amount.
NOTE:
The full-open lift amount standard temperature is the reference
value.
• After checking the full-open lift amount, lower the water tempera-
ture and check the valve closing temperature.
If out of the specification range, replace the water control valve.
INSTALLATION
Installation is in the reverse order of removal.
Water Control Valve
• Install water control valve by making O-ring (1) groove fit to water
control valve flange (A) around the whole circumference.
CAUTION:
Do not reuse O-ring.
• Install water control valve with jiggle valve (A) facing upward. The
position may deviate within the range of 20
° (b).
• Install the engine coolant temperature sensor if removed.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
21, "Recommended Chemical Products and Sealants"

WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter
of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-
ing.
REMOVAL
1. Drain engine coolant from the radiator. Refer to
CO-12, "Changing Engine Coolant"
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belts.
2. Remove the air duct. Refer to
.
3. Disconnect radiator hose (upper) at water outlet side. Refer to
.
4. Remove water outlet.
5. Remove throttle body coolant hose at heater pipe.
6. Remove heater core coolant hose at heater pipe.

7. Remove oil cooler coolant hose at heater pipe.
8. Remove oil level gauge and oil level gauge guide.
9. Remove exhaust manifold heat shield.
10. Remove heater pipe and O-ring.
CAUTION:
Do not reuse O-ring.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Do not reuse O-ring.
• Securely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.
INSPECTION AFTER INSTALLATION
• Check for engine coolant leaks. Refer to
• Start and warm up engine. Visually check for engine coolant leaks. Repair as necessary.
