WATER OUTLET AND 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 full open valve lift amount.
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.
 If out of the specification, replace water control valve.
INSTALLATION
Installation is in the reverse order of removal.
Water Control Valve
CAUTION:
Replace the rubber ring with a new one.
 Install water control valve while making rubber ring (1) groove fit to
water control valve flange (A) around the whole circumference.
 While the mark (A) points to up, install water control valve (2) with
frame center (B) facing straight upward into water outlet (1).
Water Outlet
Install the water control valve to the cylinder head without displacing the valve from the valve position.
