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 while making rubber ring (1) groove fit to water control valve flange (A) around the whole circumference.
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. Valve opening temperature 93.5 - 96.5
°C (200 - 206 °F)
Full-open valve lift amount 8 mm/ 108 °C (0.315 in/ 226 °F)
Valve closing temperature 90 °C (194 °F) PBIC3314J
PBIC3317J
PBIC4700E

- Install water hoses (3),(5) as shown.
• Electric throttle control actuator (1)
• Clamp (2)
• Water outlet (4)
• Paint mark (A)
• Clamp shall not interfere with the bulged area (B)
• : Engine front
INSPECTION AFTER INSTALLATION • Check for leaks of engine coolant. Refer to CO-35, " Inspection " .
• Start and warm up the engine. Visually check for leaks of engine coolant.

Valve opening temperature 80.5 - 83.5
°C (177 - 182 °F)
Full-open valve lift amount 8 mm/ 95 °C (0.315 in/ 203 °F)
Valve closing temperature 77 °C (171 °F) Valve opening temperature 93.5 - 96.5
°C (200 - 206 °F)
Full-open valve lift amount 8 mm/ 108 °C (0.315 in/ 226 °F)
Valve closing temperature 90°C (194 °F) Cap relief pressure
Standard 78 - 98 (0.78 - 0.98, 0.8 - 1.0, 11- 14)
Limit 59 (0.59, 0.6, 9)
