4. Check if valve is closed at 5°C(9°F) below valve opening tem-
perature. For details, refer toCO-42, "
THERMOSTAT AND
WATER PIPING".
OK or NG
OK >> GO TO 7.
NG >> Replace thermostat.
7.CHECK ENGINE COOLANT TEMPERATURE SENSOR

OK or NG
OK >> GO TO 8.
NG >> Replace engine coolant temperature sensor.
8.CHECK MAIN 12 CAUSES
If the cause cannot be isolated, go toEC-770, "
Main 12 Causes of Overheating".
>>INSPECTION END
PROCEDURE A
1.CHECK COOLING FAN POWER SUPPLY CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect cooling fan relay-1.

ground with CONSULT-II or tester.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.Valve opening temperature:
80 - 84°C (176 - 183°F) [standard]
Valve lift:
More than 10 mm/95°C (0.339 in/203°F)

lHarness for open or short between cooling fan relays-2 and -3 and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
6.CHECK COOLING FAN RELAYS-2 AND -3
Refer toEC-771, "
Component Inspection".
OK or NG
OK >> GO TO 7.
NG >> Replace cooling fan relays.
7.CHECK COOLING FAN MOTORS
Refer toEC-771, "
Component Inspection".
OK or NG
OK >> GO TO 8.
NG >> Replace cooling fan motors.
8.CHECK INTERMITTENT INCIDENT
PerformEC-699, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT".

Precautions to Handle Retractable Power Door MirrorsEIS000MD
lDo not manually operate retractable power door mirrors. If mirror
is operated manually, be sure to use the retracting switch to
move mirror fully to the opposite direction until it stops. In this
case, a loud click sound is heard, but it is not abnormal. (If mirror
body is manually moved to the neutral position, door mirror will
have some disturbing symptoms during driving, including vibra-
tion, rough retracting movement, or sometimes no retracting.)
CAUTION:
Tilting mirror body forward with excessive force may damage it.
lWhen operating retracting switch to move mirror from the neutral position to the fully-closed (backward
limit) position, at the beginning of the movement a faint click sound is heard, but it is not abnormal.
lRH and LH retractable power door mirror bodies have different mounting angles in the neutral position.
This is why the RH mirror body delays slightly when operated with the retracting switch.
NOTE:
lWhen the retractable power door mirror body is in the neutral position, if retracting switch is operated to
the opening direction while pressing it forward, mirror body is moved to the forward limit position, but it
is not abnormal. In this case, be sure to operate retracting switch to move mirror to the fully-closed
(backward limit) position.
lWhen the retracting switch is operated continuously 5 times or more, the retractable power door mirror
may be inactivated to prevent overheating. In this case, wait for approximately 5 minutes to recover.
