HV2 CHECK THE ELECTRIC COOLING FAN FOR MECHANICAL BINDING
Note: The electric cooling fan uses a viscous coupling. The viscous drag should be smooth during fan rotation. The amount of resistance is dependant upon the final cooling fan operational state before engine shutdown.
• Ignition OFF.
• Manually rotate the cooling fan.
Does the electric cooling fan rotation feel rough or binding?
Yes | No |
|---|---|
INSTALL a new Cooling Fan. REFER to the Workshop Manual Section 303-03, Engine Cooling. Clear the PCM DTCs. REPEAT the self-test. | GO to HV3 . |
