Electrical Fan Control System

SYSTEM INSPECTION






1. Ground the check connector to a ground with a jumper wire.
2. Turn the ignition switch ON and verity that the fan operates. If the fan does not operate, inspect the cooling fan system components and harness.





3. Remove the radiator cap and place a thermometer in the radiator filler neck.

4. Start the engine.

5. Verify that the fan operates when the coolant temperature reaches approx. 97.C (207.F).

If the fan does not operate, the water thermoswitch is probably at fault.


Note: The high-speed operation (provided only for ATX) cannot be checked by the inspection procedures above. The high-speed operation requires above 108.C (226.F)
