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

CO-8, "Draining"

.

CAUTION:

• Perform this step when the engine is cold.

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

CO-8, "Inspection"

.

• Start and warm up engine. Check visually that there is no leakage of engine coolant.
