Fan Clutch: Testing and Inspection
Fan Drive Clutch Test
Fig. 3 Bi-metallic coiled spring removal
Do not operate the engine until the fan has been first checked for possible cracks and separations.
To check the clutch fan, disconnect the bimetal spring and rotate 90° counterclockwise. This disables the temperature-controlled, free-wheeling feature
and the clutch performs like a conventional fan. If this cures the overheating condition, replace the clutch fan.
