    How to replace the fan clutch on Cadillac Escalade EXT? Posted by Customer
    A:
    The replacement of the Fan Clutch begins by taking off the upper Fan Shroud. Create a clamp with the Fan Clutch remover and installer (J 46406) and Fan Clutch wrench (J 41240-5A) onto the Fan Clutch to proceed. Turn the Water Pump fan nut counterclockwise to remove it from the pump before setting the Fan Blade directly on the workbench. First detach the Fan Blade by taking out bolts which secure the Fan Clutch to its rear side before fully separating the clutch from the blade. You should start with Fan Clutch bolt installation followed by the Fan Clutch assembly to the Fan Blade while strictly following fastener notice in service precautions. Secure the bolts at 23 nm torque before installing the Fan Blade. The Fan Clutch remover and installer (J 46406) along with the Fan Clutch wrench (J 41240-5A) should be reattached to the Fan Clutch before applying clockwise torque of 56 nm (41 ft. Lbs.) to the Fan Clutch nut. Reposition the upper Fan Shroud before completing the process.
