Installation Procedure

1999 GMC Forward Control 5.7 R, AutomaticSECTION Installation Procedure
WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: When replacing stationary windows, use Urethane Adhesive Kit GM P/N 12346392 (Canadian P/N 10952983), or a urethane adhesive system meeting GM Specification GM3651G, to maintain original installation integrity. Failure to use the urethane adhesive kit will result in poor retention of the window which may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.
  1. Verify all primers and urethane adhesive are within expiration dates.

    Important:  Use care when applying the prep, clear #1, to the window. This primer dries almost instantly, and may stain the viewing area of the window if not applied evenly.

  2. Use a new dauber in order to apply glass prep, clear #1, to the channel area approximately 13 mm (1/2 in) to the upper edge of the window.

  3. Wipe the glass primed area immediately with a clean lint-free cloth.
  4. Shake the glass primer, black #2, for at least 1 minute.
  5. Use a new dauber in order to apply glass primer, black #2, to the top edge of the window.
  6. Apply a small bead of urethane adhesive (2) between the window (1) and the pinch-weld.

  7. Reinstall the window reveal molding.
    1. 7.1.  Start from the loose area and hand-press the reveal molding into place over the edge of the window.
    2. 7.2.  Run warm water over the reveal molding in order to speed the setup time of the urethane adhesive.
    3. 7.3.  Tape should be applied in order to retain the reveal molding to the window. This will maintain a flush fit with the body.
    4. 7.4.  The tape is to be removed after 6 hours.
