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 th ick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
CAUTION:
• When removing water pump assembly, be car eful not to get coolant on drive belt.
• Water pump cannot be disassembled and should be replaced as a unit.
• After installing water pump, connect hose and clamp securely, then check for leaks using radiator
cap tester.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.

• Place a thread so that it is caught
in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.
• The valve opening temperature is the temperature at which the
valve opens and the thermostat falls from the thread.
• Continue heating. Check the full-open lift amount. NOTE:
The full-open lift amount standard temperature for the thermostat is
the reference value.
• After checking the full-open lift amount, lower the water tempera-
ture and check the valve closing temperature.
• If valve setting at measured values are out of standard range, replace thermostat.
INSTALLATION
Installation is in the reverse order of removal.
• Install the thermostat with the whole circumference of the flange fit-
ting securely inside the rubber ring.
• Install the thermostat with the jiggle valve facing upwards. The
position deviation may be within the range of ±10 °.
• After installation, refill coolant and check for leaks. Refer to CO-
12, "Changing Engine Coolant" and CO-11, "System Inspection".
