    Fig. 3: Exploded view of the engine fan for the 4.0L engine

     

    Click image to see an enlarged view
    Fig. 4: Before attempting to unfasten the engine fan, check the fan shroud for indications of normal or reverse threads

     

    Click image to see an enlarged view
    Fig. 5: Remove the air intake tube. You will need these specialized tools to unfasten the fan clutch nut

     

    1. If necessary, remove the air cleaner outlet tube.

    According to the manufacturer, the nut uses LH threads and is loosened clockwise.

    1. Using Fan Clutch Pulley Holder T84T-6312-C and Fan Clutch Nut Wrench T84T-6312-D, or their equivalents, loosen the large nut attaching the clutch to the water pump hub.

    Click image to see an enlarged view
    Fig. 6: Using the special tools, loosen the fan clutch nut in the direction indicated on the shroud.

     

    Some models have enough room between the shroud and the engine to remove the fan without unbolting the shroud.

    1. Remove the two upper fan shroud retaining bolts. If the overflow hose is routed through the fan shroud, remove it from the shroud.

    2. Lift up on the fan shroud to disengage the lower mounting clips.

    Fig. 7: Remove the fan and clutch assembly from the vehicle

     

    1. Remove the fan/clutch assembly and the fan shroud together.

    2. If necessary, remove the fan-to-clutch bolts to separate the fan from the clutch.

    Eric: We appreciate your efforts and instructions but they are useless to us because the fan, which is the original, mounted on the water pump is NOTHING like what you are showing or describing. There are no bolts on the front side of the clutch and no way of removing that big nut between the wate pump and the fan. I give up and have to have a mechanic.

    No.... I have a serpentine belt and it is nothing like your image. Also there is just a large nut between the fan and the water pump.
    Ford Mechanic: Eric, Automotive Repair Shop Manager replied 10 years ago

    Hi,

    Not sure what to tell you, that image is straight out of 1994 Ford Ranger service manual

    We regret that the information you described and the time you gave us does not help in our situation. Thank you for trying, but we remain in the same predicament as when we started. We still cannot remove the fan and clutch from the water pump shaft and will try to get a mechanic to come and do it.
