Ok ,now I know the whole story.One of the assembly bolts wiggeled out of the alternator and got in way of the alternator fan ,not my mechanics fault.In some far off country is a nut laying on a table looking for its partner, the bolt.Assembly class should maybe try a little do dilagence on their assembly steps one more time.Oriellys guy at the counter had ask if the nut was still in the box and my reply was just a smile and a look.My reply should of been ,your about to have a nut on your hands.
