Tools Required

1. Remove the roof lift off panel (coupe) or lower the folding top (convertible).
2. Lower the door windows.
3. Open the hood.
4. Remove the windshield wiper arms. Refer to Windshield Wiper Arm Replacement in Washers and Wipers.



5. Remove the plenum to hood seal. Refer to Hood Rear Seal Replacement in Body Front End.



6. Carefully remove the air inlet plenum screen panel. Refer to Air Inlet Screen Replacement in Washers and Wipers.



7. Mark the location of the lower windshield supports with a grease pencil or tape.
8. Remove the lower windshield supports.



9. Remove the rearview mirror. Refer to Inside Rearview Mirror Replacement
10. Disconnect the windshield antenna lead connection (if equipped).

Caution: If broken glass falls into the defroster outlets, it can be blown into the passenger compartment and cause personal injury.

11. Tape over the defroster outlets.
12. Cover the vehicle interior to protect the interior from broken glass.
13. Apply tape to the painted surfaces around the windshield in order to prevent paint damage.



14. Remove the windshield weather-strip. Refer to Weatherstrip Replacement .



15. Remove the windshield side reveal moldings. Refer to Windshield Side Reveal Molding Replacement .



16. Remove the windshield side garnish moldings.

Pull the molding with its retainers from the windshield frame.




17. Remove the 4 rearmost screws attaching the top of the fender to the wheelhouse.
18. Reposition the fender for tool access.



19. Tape or otherwise protect the fender from the cutting tool.

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.

Important: Keep the cutting edge of the tool against the windshield when removing the windshield. This will allow the urethane adhesive to be separated from the windshield. Leave a base of urethane on the pinchweld flange. The only suitable lubrication is clear water.

20. Cut out the windshield useJ 24402-A J 39032 cold knife, to remove the windshield.



21. Remove the windshield from the vehicle with the aid of an assistant.
22. Inspect the following components for the causes of a broken windshield:

•	The flange of the windshield opening

•	The windshield reveal molding

•	The windshield

23. Inspect for any of the following problems in order to help prevent future breakage of the windshield:

•

High weld

•	Solder spots

•	Hardened spot weld sealer

•	Any other obstruction or irregularity in the pinchweld flange.

Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs or replacements are required, the pinchweld flange must be refinished in order to restore the bonding area strength. If paint repairs are required, mask the flange bonding area prior to applying the color coat in order to provide a clean primer only surface. Materials such as BASF DE17®, DuPont  2610®, Sherwin-Williams PSE 4600 and NP70 ® and Martin-Semour 5120 and 5130 ® products are approved for this application.

24. After repairing the opening as indicated, perform the following steps:

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.

After repairing the opening as indicated, perform the following:

1. Shake the pinchweld primer (black #3) for at least one minute.




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.

2. Use a new dauber to apply the pinchweld primer (black #3) to the surface (1) of the bonding area.
3. Allow the primer to dry for approximately 10 minutes. Ensure that all nicks and scratches are covered.



4. Install the lower windshield supports (1) to the cowl panel, if equipped.



5. If using extended method, install the spacers and the VIN plate filler strip.



6. Install the reveal molding to the edge of the windshield. If the original reveal molding is damaged it must be replaced.
7. Install a new acoustic strip if needed.

1. If using extended method, install the spacers and the VIN plate filler strip.

Inspect the acoustic strip on the dash panel and replace if necessary.

2. With the aid of an assistant, dry fit the windshield in the opening in order to determine the correct way to position the windshield in the opening.
3. Carefully inspect the windshield overlap at the body pinch-weld and the retaining flanges all the way around the body opening.

Specifications
The minimum overlap should be 5.0 mm (0.19 in).




4. Mark the windshield position at the following locations using masking tape.



5. Install the windshield supports if using the extended method.

Press the supports firmly onto the panel.




6. Place the windshield on the lower supports (1).



7. With the aid of an assistant, use the suction cups in order to install the windshield window into the opening.



8. Align the tape (1) lines on the windshield and the body.
9. Press the windshield firmly into place.
10. Tape the windshield to the body in order to minimize movement until the urethane adhesive cures.
11. Clean any excess urethane adhesive from the body.




Important: Do not direct a hard stream of high pressure water to the freshly applied urethane adhesive.

12. Use a soft spray of warm water in order to immediately water test the windshield window.
13. Inspect the windshield for leaks.
14. If any leaks are found, use a plastic paddle in order to apply extra urethane adhesive at the leak point.
15. Retest the windshield for leaks.

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.

16. The following conditions must be maintained to properly cure the urethane:

16.1.

Allow the vehicle to remain at room temperature (21°C or 70°F) at 30 percent relative humidity.

16.2.

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

16.3.

Allow a minimum of 1 hour to 1 1/2 hours for the chemical curing urethane adhesive.

16.4.

Partially lower a door window in order to prevent pressure buildups when closing doors before the urethane adhesive cures.

16.5.

Do not drive the vehicle until the urethane adhesive is fully cured. Refer to the above curing times.

16.6.

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




17. Cut the tape used to mark the location of the windshield.



18. Remove the windshield from the body opening.



19. Install the windshield side reveal moldings. Refer to Windshield Side Reveal Molding Replacement .



20. Install the windshield weather-strip. Refer to Weatherstrip Replacement .




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

21. Install the fender mounting screws.

Tighten
Tighten the fender upper flange screws to 1.9 N·m (17 lb in).




22. Install the air intake plenum screen. Refer to Air Inlet Screen Replacement in Washers and Wipers.



23. Install the plenum to hood seal. Refer to Hood Rear Seal Replacement in Body Front End.
24. Install the windshield wiper arms and washer hoses. Refer to Windshield Wiper Arm Replacement in Washers and Wipers.



25. Install the windshield side garnish moldings.



26. Install the inside rearview mirror.

Tighten
Tighten the rearview mirror mount tension screw to 1.5 N·m (13 lb in).

27. Connect the mirror electrical connector.
28. Connect the windshield antenna lead connection (if equipped).
29. Leave the windows open to avoid causing pressure when closing the doors. Air pressure could cause a leak in the urethane adhesive.
30. Close the hood.



31. Install the roof lift off panel (coupe) or raise and close the folding top (convertible).
32. Allow the windshield urethane adhesive to cure.
