On certain vehicles, the plastic blades of the cooling fan may separate and penetrate the shroud. If this occurs while the hood is open, a person in the vicinity of the engine could be struck by the blade and injured. Correction: Dealers will replace the electric cooling fan module. Note: This only applies to certain 4.7L equipped vehicles built from Jan 31, 2000 to June 12, 2000 and certain 4.0L vehicles built from Feb 4, 2002 to June 17, 2002.
