ISSUE:

Some 2004-2007 E-Series 350/450, 2003-2005 Excursion, and 2003-2007 F-Super Duty vehicles, equipped with the 6.0L diesel engine, may exhibit improper engine cooling fan clutch operation due to its wire harness being cut by the rotating cooling fan.

ACTION:

If the fan stator/shroud retaining clip is broken or missing, use the following Service Procedure to secure the wire harness to the fan stator/shroud.

SERVICE PROCEDURE

  1. A cut wire harness will prevent proper fan clutch operation. If the harness is damaged or severed, replace the Cooling Fan Clutch Assembly per the Work Shop Manual, Section 303-03. The harness may be cut because the molded-in retaining clip on the fan stator/shroud that secures the harness to the fan stator/shroud is broken or missing, allowing the loose harness to move into the rotating fan (Figure 1). Secure the harness to the fan stator/shroud using a screw to secure it to the stator/shroud.


    Figure 1 – Article 07-3-10

  2. Carefully drill a 1/8″ (3.2 mm) diameter hole through both the tab on the harness and the stator/shroud as shown (Figure 2). Hold the harness fully down in the stator/shroud slot while drilling the hole in order to assure that the harness will be positioned away from the rotating fan.


    Figure 2 – Article 07-3-10

  3. Install and tighten the screw to 9 lb-in. (1 N-m).
  4. Check to make sure that the harness is held securely to the stator/shroud and away from the fan.
