Astro Van AWD V6-4.3L VIN X (2003)
6. Misalignment of the pulleys may be caused from incorrect mounting of the accessory drive component, incorrect installation of the accessory drive
component pulley, or the pulley bent inward or outward from a previous repair. Test for an incorrectly aligned pulley. Use a straight edge in the
pulley grooves across two or three pulleys. If a misaligned pulley is found, refer to that accessory drive component for the correct installation
procedure.
10. Inspection of the fasteners eliminates the installment of incorrect: bolts, nuts, spacers, or washers.
12. Inspecting the pulleys for being bent should include inspecting for a dent or other damage to the pulleys that would prevent the drive belt from not
seating correctly in all of the pulley grooves or on the smooth surface of a pulley when the back side of the belt is used to drive the pulley.
14. Replacing the drive belt when it is not damaged, or if there is no excessive pilling will be a temporary repair.
