Windshield Replacement
REMOVAL PROCEDUREWindshield Replacement: Removal Procedure:
CAUTION: When replacing stationary windows, urethane kit GM PIN 12346284 or equivalent must be used to maintain original installation integrity. Failure to use the urethane kit will result in poor retention of the windshield which may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.
CAUTION: When you are working with any type of glass, use approved safety glasses and gloves to reduce the chance of personal injury.
Tools Required
^ J 24402-A Stationary Window Removal Tool
^ J 36863 Glass Removal Kit
^ J24811 Adhesive Dispensing Gun
1. Remove the windshield side reveal moldings.
2. Cut the outer lip of the upper reveal molding off with a urethane razor knife or equivalent to allow access to the body pinchweld.
3. Remove the windshield wiper arms.
4. Remove the air inlet grille from the cowl area.
5. Remove the rearview mirror.
6. Remove the windshield garnish molding.
7. Mask off the area around the windshield to protect the painted surface.
CAUTION: If broken glass falls into the defroster outlets, it can be blown into the passenger compartment and cause injuries. To help avoid personal injury, cover the defroster outlets before replacing windows.
8. Place a protective covering over the top of the instrument panel making sure the defroster vents are covered to prevent foreign objects from entering the outlets.
9. Working outside the vehicle, cut out the windshield using a J24402-A.
10. It may be necessary to use a wire type cutting tool to cut around the lower corners of the windshield to clear the fenders.
Windshield Replacement: Removal Procedure:
11. Remove the windshield with the aid of a helper and the suction cups from the J 36863.
12. Remove all of the urethane from the body pinchweld using a sharp scraping tool.
13. Remove all of the urethane from the windshield using a sharp scraping tool.
CLEANING PROCEDURE
Windshield Replacement: Cleaning Procedure:
1. Clean all loose urethane and debris using a vacuum.
2. Wipe the body pinchweld flange with a clean dry cloth.
IMPORTANT: Ensure that the window opening is properly prepared before window installation.
3. If there is corrosion on the pinchweld or if sheet metal repairs or replacements are required, the pinchweld flange must be refinished to present a PRIMER ONLY surface.
4. If paint repairs are required, mask the flange bonding area (prior to applying the color coat) to provide a PRIMER ONLY surface.
5. The appropriate materials for these primer applications are typically two component, catalyzed products such as BASF DE 17, DUPONT 2610, PPG DP90 (or equivalent) applied by following the manufactures directions for mix, application and drying times.
6. After repairing the window opening as indicated, shake the pinchweld primer #3 (black) well d using a new dauber, apply the primer to the bonding area of the pinchweld. Allow to dry for 10 minutes.
INSTALLATION PROCEDURE
1. Install the upper reveal molding on the windshield.
Windshield Replacement: Installation Procedure:
2. Dry fit the window into the body opening to determine the correct position by:
^ Dry fit the window into the body opening to determine the correct position by:
^ Positioning the window into the opening.
^ Using masking tape, mark, the location of the window into the opening on at least one horizontal edge (1) and one vertical edge (2) of the window.
^ Slit the masking tape at the window edges and remove the window from the body opening.
^ Place the windshield on a clean protected work surface with the inside of the windshield facing up.
Windshield Replacement: Installation Procedure:
3. Install the acoustic strip (2) with a 2 mm or less gap (3) to the dashed line (1) painted on the windshield.
IMPORTANT: The application of primers important as they act as the agent that will bond the urethane to the windshield. Be sure to use the specified primer for each application listed below for proper adhesion.
4. Shake the pinchweld primer #3 (black) well and apply it to any exposed painted surfaces (or scratches to any bare metal) on the body pinchweld flange. Allow to dry for 10 minutes.
5. Care should be taken to prevent the glass prep #1 (clear) from running the vision area of the window. This primer dries almost instantly, but may stain the viewing of the window if not applied evenly.
Windshield Replacement: Installation Procedure:
6. Using a new dauber, apply the glass prep #1 (clear) around the entire perimeter of the inner surface and any exposed edges of the window. Wipe the surface dry with a clean cloth.
Windshield Replacement: Installation Procedure:
7. Shake the primer #2 (black) well and using a new dauber apply the primer around the edges of the windshield, 15 mm (5/8 in) inboard on the inner surface, over the same area that the glass prep #1 (clear) was applied.
8. Allow the primer to dry for 10 minutes.
Windshield Replacement: Installation Procedure:
9. Install a tube of urethane in the J 24811.
Windshield Replacement: Installation Procedure:
10. Apply the urethane adhesive to the windshield.
11. Apply a bead (1) 8 mm (5/6 in) height (6) and 14 mm (9/16 in) wide (5).
Windshield Replacement: Installation Procedure:
12. Install the windshield with the aid of a helper and the suction cups from the J 36863.
13. Press firmly on the windshield to wet-out and set the urethane adhesive.
14. Tape the windshield at the top using four pieces of tape.
15. Watertest the windshield immediately using a soft spray. Warm or hot water is preferred to accelerate the curing of the adhesive. DO NOT direct a hard stream of high pressure water at the fresh urethane adhesive.
Windshield Replacement: Installation Procedure:
16. If a leak is detected apply urethane adhesive to the leak point and 127 mm (5 in) on both sides of the leak point using a flat bladed tool.
IMPORTANT: The following steps must be taken before completing the installation procedure.
^ Allow the vehicle to remain at room temperature 22°C (72°F) at 30% relative humidity for a minimum of 6 hours.
^ Lower the door windows partially to prevent pressure build up when closing the doors prior to the urethane adhesive curing.
^ DO NOT DRIVE THE VEHICLE until the urethane is cured a (minimum 6 hours at room temperature).
^ DO NOT USE COMPRESSED AIR to dry the urethane adhesive
Windshield Replacement: Installation Procedure:
17. Remove the masking tape from the windshield after the urethane has cured.
18. Install the air inlet grille panel.
19. Install the windshield wiper arms.
20. Install the windshield side reveal moldings.
21. Install the windshield garnish molding.
22. Install the rearview mirror.
