Tools Required

Caution: When working with any type of glass or sheet metal with exposed or rough edges, wear approved safety glasses and gloves in order to reduce the chance of personal injury.

1. Place protective coverings around the window removal area.
2. Apply masking tape to the painted surfaces around the windshield in order to prevent damage to the paint.
3. Remove the windshield wiper arms.

Caution: Failure to cover the defroster outlets, when replacing windows, can cause broken glass to be expelled when the defroster is operated, resulting in personal injury.

4. Remove the air inlet grill panel screen. Refer to Defroster Grille Replacement in Instrument Panel, Gauges and Console.
5. Remove the ramps from the cowl area.
6. Remove the rearview mirror. Refer to Inside Rearview Mirror Replacement
7. Remove the A-pillar trim. Refer to Windshield Pillar Garnish Molding Replacement in Interior Trim.
8. Remove the windshield reveal molding.
9. Remove the roof weld joint reveal molding. Refer to Roof Weld Joint Reveal Molding Replacement in Exterior Trim.

9.1.	Grasp the lower corner of the windshield reveal molding by hand.

9.2.	Slowly pull the reveal molding from the windshield.

9.3.	If the windshield reveal molding does not release, use a utility knife in order to cut around the windshield.

9.4.	The windshield reveal molding fills the cavity between the body and the windshield.

Do not reuse the reveal molding, if the molding is stretched or damaged.





Important: Keep the cutting edge of the tool against the windshield. This separates the urethane adhesive from the windshield.

10. Use the J 24402-A and the J 39032 in order to remove the windshield.
11. With the aid of an assistant, remove the windshield.
12. The following components may reveal the causes of a broken windshield:

•	The flange of the windshield opening

•	The windshield reveal molding

•	The windshield

13. Look for any of the following conditions in order to prevent damage to the windshield:

•	A high weld

•	Solder spots

•	Hardened spot weld sealer

•	Any obstruction or irregularity in the pinchweld flange

14. Inspect the condition of the windshield opening and the adhesive bead in order to determine which installation method you will use. Refer to Short Method Description or Extended Method Description .

Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs or replacements are necessary, refinish the pinchweld flange in order to present a clean primer only surface. If repairs to the paint are required, mask the flange bonding area prior to the application of the color coat in order to provide a clean primer only surface. Use material such as BASF DE17®, DuPont 2610®, and PPG DP40®.

15. Thoroughly shake the pinchweld primer (#3 black).



16. Use a new dauber in order to apply the primer to the primed surface on the flange in the bonding area (1).
17. Allow approximately 10 minutes for drying the primer.

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.

1. With the aid of an assistant, dry fit the window in the opening in order to determine the correct position.



2. Use masking tape in order to mark the location of the windshield (1) in the opening.
3. Slit the masking tape at the top edge of the windshield.
4. Remove the windshield.
5. Place the windshield on a clean, protected surface.

The inside of the windshield faces up.

6. If the you reuse the original window, remove all but a thin film of the existing urethane adhesive from the window surface.

Use a utility knife.

7. Clean with GM Glass Cleaner P/N 1050427 or the equivalent the inside surface of the windshield.

Important: Do not remove all traces of the adhesive.

8. Remove any mounds or loose pieces of the adhesive.
9. If you use the extended installation method, perform the following steps:

9.1.	Remove all but a thin film of the existing bead of adhesive from the pinchweld flange.

9.2.	Thoroughly shake the pinchweld primer (#3 black).

9.3.	Use a new dauber in order to apply the primer to exposed painted surfaces or scratches in the flange in the bonding area.

9.4.	Allow approximately 10 minutes for drying the primer.

10. Install the windshield reveal molding to the edge of the windshield.

Replace the original molding, if the original molding is damaged.

Notice: Failure to install the acoustic strip could cause windshield breakage.

11. Install the new acoustic strip on the windshield.



12. If you use the extended method, apply a dam material, such as Norton® Windshield Dam Replacement or the equivalent, in order to control excess urethane.

Apply the dam material approximately 12-18 mm (1/2-5/8 in) from the outer edge of the window around the perimeter of the window.

Important: Use care when applying the windshield prep (#1 clear) in order to prevent the windshield prep from running into the vision area of the windshield. This primer dries almost instantly. This primer may stain the view area of the windshield.

13. Using a new dauber, apply window prep (#1 clear) to an area approximately 10-16 mm (3/8-5/8 in) around the entire perimeter of the glass inner surface.
14. Apply windshield prep (#1 clear) to any exposed edges of the window.
15. Immediately wipe the primed area with a clean cloth.



16. Thoroughly shake the windshield primer (#2 black).
17. Using a new dauber, apply the windshield primer (#2 black) to the same areas (2) where you applied the windshield prep (#1 clear).
18. Allow approximately 6 minutes for drying the primer.



19. Prior to application of the urethane adhesive, cut the tip of the applicator nozzle (1) in order to provide the following bead sizes:

•	For the short method, cut the tip in order to provide an adhesive bead of approximately 4.5 mm (1/8-3/16 in).

•	For the extended method, cut the tip in order to provide an adhesive bead of approximately 14 mm (9/16 in).




20. Using a cartridge-type caulking gun, apply a smooth continuous bead of urethane adhesive.
21. When using the short installation method, apply the urethane adhesive to the existing bead of urethane adhesive on the body.



22. When using the extended installation method, use the edge (2) of the window or the inside edge of the reveal molding as a guide for the nozzle.



23. With the aid of an assistant, use rubber suction cups in order to install the window in the opening.



24. Align the tape (1) on the windshield (2) and on the body.
25. Press firmly the windshield into place.
26. Tape the windshield to the body in order to minimize movement.
27. Remove any excess urethane adhesive.




Important: Warm or hot water accelerates the cure of the adhesive. Do not direct a hard stream of high pressure water at the fresh urethane adhesive.

28. Use a soft spray of warm water in order to immediately water test the windshield.
29. Inspect the windshield for leaks.
30. If you found any leaks, use a plastic paddle in order to apply extra urethane at the leak point.
31. Complete the following steps in order to properly cure the urethane adhesive:

•	Keep the vehicle at a room temperature of 22°C (72°F) at 30 percent relative humidity.

•	Allow a minimum of 6 hours for the moisture curing urethane adhesive.

•	Allow a minimum of 6 hours for the chemical curing urethane adhesive.

•	Partially lower a door window in order to prevent pressure build-ups when you close doors prior to the urethane adhesive cure.

•	Do not drive the vehicle until the urethane adhesive is cured.

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

32. Install the remaining reveal moldings as needed. Refer to Roof Weld Joint Reveal Molding Replacement in Exterior Trim.
33. Install the A-pillar trim. Refer to Windshield Pillar Garnish Molding Replacement in Interior Trim.
34. Install the air inlet grill panel screen. Refer to Defroster Grille Replacement in Instrument Panel, Gauges and Console.
35. On Oldsmobile models, install the roof molding.
36. Install the wiper ramps.
37. Install the windshield wiper arms.
38. Install the rearview mirror. Refer to Inside Rearview Mirror Replacement .
39. Remove the protective tape and the coverings.
