  8. Remove the I/P upper trim pad. Refer to Instrument Panel Upper Trim Pad Replacement in Interior Trim.
  9. Cover the defroster outlets.
  10. Remove the inside rearview mirror. Refer to Inside Rearview Mirror Replacement .
  11. Use the Installing the Case Bushing or the equivalent cut around the perimeter of the windshield from inside the vehicle.
  12. Caution: If a window is cracked but still intact, crisscross the window with masking tape in order to reduce the risk of damage or personal injury.

  13. Remove the windshield (1).

Installation Procedure

Tools Required

    • A solvent for cleaning the edge of the window. Use GM Glass Cleaner P/N 1050427 or isopropyl alcohol
    • A household cartridge type caulking gun
    • A commercial type razor knife in order to cut around the edge of the window
    • Rubber suction grips
  1. Install the I/P upper trim pad. Refer to Instrument Panel Upper Trim Pad Replacement in Interior Trim.

  2. Object Number: 296235  Size: SH
  3. With the aid of an assistant, dry fit the windshield (1) in the opening to determine the correct position. Use the following procedure:
  4. 2.1. Position the windshield (1) in the opening.
    2.2. Use masking tape in order to mark the location of the windshield (1) in the opening.
    2.3. Slit the masking tape at the window edge.
    2.4. Remove the windshield (1) from the opening.
    2.5. Place the windshield (1) inside up on a clean protected surface.
  5. Clean the surface around the inside edge of the windshield (1) where the urethane adhesive will be applied. Use a dampened cloth with either isopropyl alcohol or GM Window Cleaner P/N 1050427 or the equivalent.
  6. 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.

    Caution: Failure to prep the area prior to the application of primer may cause insufficient bonding of urethane adhesive. Insufficient bonding of urethane adhesive may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.

  7. If you are using the extended method of installation, perform the following:
  8. • Shake the pinchweld primer #3 (black) well.
    • Apply the primer to any exposed painted surfaces (or scratches to bare metal) on the pinchweld flange.
    • Allow the primer to dry 10 minutes.
  9. If you are using the short method, DO NOT prime the existing bead of urethane adhesive on the body.
  10. Refinish the pinchweld flange in order to present a Primer Only surface if the following conditions exist:
  11. • Corrosion of the pinchweld flange is present
    • Sheet metal repairs or replacements are required
    • If paint repairs are required, mask the flange bonding area first
    • Appropriate materials for these primer applications are typically two component, catalyzed products such as BASF DE17, DUPONT2610, PPG DP90 or equivalent applied by following the manufacturers directions for mix, application and dry times.
    • After repairing the opening as indicated, perform the following:
       • Shake the pinchweld primer #3 (black) well.
       • Apply the pinchweld primer to the primed surface of the flange in the bonding area.
       • Allow to dry 10 minutes.
  12. If reusing the original windshield (1) , remove any existing urethane adhesive from the windshield (1) edge and surface. Use a razor knife or the equivalent.
  13. If you are using the original reveal molding (2) or production type reveal molding, install the molding (2) along the edge of the window.
  14. Install a new sealing strip weatherstrip (5) on the windshield (1), as needed.
  15. If you are using the extended method, use the following procedure:
  16. • Apply a dam material approximately 12 to 18 mm (0.47 to 0.71 in) from the outer edge of the window and around the perimeter of the window to control urethane squeeze out.
    • For dam material, use Norton Windshield Dam Replacement.

       Important: Do not allow the window preparation #1 (clear) to drip or spill onto the vision area of the windshield (1). The primer dries instantly and may stain the viewing area if not applied evenly.


    Object Number: 296237  Size: LH
  17. Use a new dauber to apply the glass preparation #1 (clear) approximately 10 to 16 mm (0.39 to 0.63 in) around the entire perimeter of the inner surface. Also apply the glass preparation to any exposed edge of the window (2).
  18. Wipe dry the area using a clean cloth.

  19. Shake the window primer #2 (black) well. Use a new dauber to apply the primer over the glass preparation #1 (clear) that was applied in the previous step.
  20. Allow the primer to dry for 6 to 10 minutes.
  21. Important: Do not apply the clear primer over the black primer. Do not touch the primer coated surface.

  22. If you are using the short method, cut the tip of the applicator nozzle to provide a bead of urethane adhesive 4.5 mm (0.18 in) in diameter.
  23. If you are using the extended method, cut the applicator nozzle to provide a bead of urethane adhesive 7-8.5 mm (0.28 to 0.33 in) wide by 14-15.5 mm (0.55 to 0.61 in) high.
  24. Use a cartridge type caulking gun in order to apply a smooth continuous bead of urethane adhesive.
  25. Use either of the 2 following procedures:

    • For the short method, apply urethane adhesive to the existing bead of urethane adhesive on the body.
    • For the extended method, use the edge of the windshield (2) or the inside edge of the reveal molding (3) as a guide for the nozzle.
    • Apply the urethane adhesive to the inner surface of the windshield (2).
    • Use rubber suction cups to install the windshield (2).
    • Use as assistant to help with the installation.
  26. Align the windshield (2) with the previously installed masking tape.
  27. Firmly press the windshield (2) into place.
  28. Tape the windshield (2) to the body in order to minimize movement and in order to clean up any urethane squeeze out.
  29. Important: Do not direct a hard stream of high pressure water at the fresh adhesive.

  30. Immediately watertest the window.
  31. Use a soft spray of warm or hot water in order to accelerate the cure of the adhesive.
  32. Refer to Water Hose Test in Waterleaks for the water test procedures.

  33. If leaks are found, use a plastic paddle in order to apply extra urethane adhesive at the leak point.
  34. Remove the protective tape and coverings.
  35. Caution: At least 24 hours are required for complete curing of repair material. The repair area should not be physically distrubed until after that time. Insufficient curing of urethane adhesive may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.

  36. Allow the vehicle to remain at room temperature, 22°C (72°F) and 30 percent relative humidity for a minimum of 6 hours.
  37. Partially lower a door window in order to prevent pressure build up when closing the doors before the urethane adhesive cures.
  38. Do not drive the vehicle until the urethane adhesive is cured.

    Do not drive the vehicle for a minimum of 6 hours.

    Do not use compressed air in order to dry the urethane adhesive.

  39. Install the T-tops, if equipped.
  40. Install the air inlet grille. Refer to Air Inlet Grille Panel Replacement in Body Front End.
  41. Install the wiper arms. Refer to Windshield Wiper/Washer Systems.
