REMOVAL
1. Drain engine coolant from radiator. Refer to
CO-36, "Changing Engine Coolant".
CAUTION:
• Perform this step when engine is cold.
• Never spill engine coolant on drive belt.
2. Remove the air duct (inlet). Refer to EM-135, "
Component".
3. Remove the radiator hose (lower) from the engine. Refer to CO-40, "
Component".
4. Remove water inlet.
5. Remove thermostat.
6. Remove water pump, if necessary. Refer to CO-45
.
7. Remove thermostat housing, if necessary.
INSPECTION AFTER REMOVAL
• Place a thread (A) so that it is caught in the valves of thermostat (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 full-open valve lift amount. NOTE:
The full-open valve lift amount standard temperature for the ther-
mostat is the reference value.
• After checking the full-open valve lift amount, lower the water tem-
perature and check the valve closing temperature.
• If out of the specification, replace thermostat.

WATER OUTLET AND WATER CONTROL VALVE
• Place a thread (A) so that it is c
aught 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 full-open valve lift amount.
NOTE:
The full-open valve lift amount standard temperature for water con-
trol valve is the reference value.
• After checking the full-open valve lift amount, lower the water tem- perature and check the valve closing temperature.
• If out of the specification, replace water control valve.
INSTALLATION
Installation is in the reverse order of removal.
• Use the following procedure to install the water control valve.
- Install water control valve making sure rubber ring (1) groove fits
securely to water control valve flange (A).
CAUTION:
Replace the rubber ring with a new one.
- While the mark (A) points to up, install water control valve (2) with frame center (B) facing straight upward into water outlet (1).
• Use the following procedure to install the water outlet.
- Install the water outlet to the cylinder head without disp lacing the water control valve from the valve position.
• Use the following procedure to install the water hoses. Standard : Refer to
CO-55, "
Standard and Limit"
