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 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.
REMOVAL
1. Drain engine coolant from the radiator. Refer to
.
CAUTION:
• Perform this step when the engine is cold.
• Do not spill coolant on drive belt.

Inspection
INFOID:0000000011279717
INSPECTION AFTER REMOVAL
• Place a thread (A) so that it is caught in the valves of thermostat
(1) and water control valve. Immerse fully in a container (B) filled
with water. Heat while stirring. (The example in the figure shows
thermostat.)
• The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
• Continue heating. Check the maximum 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 standard, replace either or both thermostat and water control valve.
INSPECTION AFTER INSTALLATION
• Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to
.
• Start and warm up engine. Check visually that there is no leakage of engine coolant.
