  4. Remove the engine cooling fan blade nut.
  5. Remove the engine cooling fan blade.
    CAUTION: If a fan blade is bent or damaged in any way, do not repair or reuse the damaged part. Always replace a bent or damaged fan blade. Fan blades that have been damaged can not be assured of proper balance and could fail and fly apart during subsequent use. This creates an extremely dangerous situation.

    The fan blades must remain in proper balance. You cannot assure fan blade balance once a fan blade has been bent or damaged. A fan blade that is not in proper balance could fail and fly apart during use, creating an extremely dangerous situation.

  6. Inspect the cooling fan for the following conditions:
    • Bent or cracked cooling fan blades
    • Smoothness of the cooling fan blade mating surfaces
    • Remove burrs or other imperfections as necessary
