FAN CLUTCH WITH COOLING FAN
INSPECTION AND REPAIR
Make necessary correction or parts replacement if wear, damage or any other abnormal condition are found through
inspection.


033R300001
Visually inspect for damage, leak (sillicon grease) or other
abnormal conditions.
1. Inspection (on-vehicle)
1) Turn the fan clutch by hand when in a low temperature condition before starting the engine, and confirm that it
can be turned readily.
2) Start the engine to warm it up until the temperature at the fan clutch portion gets to around 80 °C. Then stop
the engine and confirm that the fan clutch can be
turned with considerable effort (clutch torque) when
turned by hand.
If the fan clutch rotates more readily, however, this indicates that the silicone grease is leaking internally.
Replace the fan clutch with a new one.



033RY00011
2. Inspection (in unit)
W arm up the bimetal of the fan clutch by using the heat
gun until the temperature gets to about 80 °C when
measured with the thermistor. Then confirm that the fan
clutch can be turned with considerable effort (clutch
torque).
If the fan clutch retates more readily at this time, this
indicates that the silicone grease is leaking internally.
Replace the fan clutch with a new one.

entering.
3. Jack up the vehicle.
4. Support underneath of the fuel tank with a lifter.
5. Remove the inner liner of the wheel house at rear left side.
6. Remove fixing bolt of the filler neck from the body.
7. Disconnect the quick connector (3) of the fuel tube from the
fuel pipe.
NOTE: Cover the quick connector to prevent any dust entering
and fuel leakage.
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in this
section when performing any repairs.
8. Remove fixing bolt (1) of the tank band and remove the tank band (2).
9. Disconnect the pump and sender connector on the fuel
pump and remove the harness from weld clip on the fuel
tank.
10. Lower the fuel tank (5).
NOTE: W hen lower the fuel tank from the vehicle, don’t scratch
each hose and tube by around other parts.













Installation
1. Raise the fuel tank.
