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: 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.

Tools Required

Important: Do not damage the VIN plate when cutting through the urethane.

18. Cut out the windshield.

•	Cut around the periphery of the windshield.

•	Cut next to the windshield.

•	Use a cold knife or a pneumatic knife.




19. Remove the windshield from the body opening.
20. Remove the old urethane from the windshield opening leaving a thin film 1-2 mm (1/16 in) of adhesive on the pinch-weld.

22. Remove any old adhesive from a reusable windshield.

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: 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.

Notice: Until the new urethane has cured, air pressure from a closing door may cause the stationary window to move causing a leak. To prevent this, lower a window before closing the door.

1. Inspect the acoustic strip on the dash panel and replace if necessary.
2. Using suction cup holders or with the aid of a helper dry fit the window by position the replacement windshield in the body 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:

•	The windshield pillars

•	The lower edge

•	The upper edge

5. Cut the tape.



6. Remove the windshield from the body opening.
7. Place the windshield inside up on a clean protected surface.
8. Clean the replacement windshield surface to which urethane adhesive is to be applied with an isopropyl alcohol dampened cloth, or use GM Window Cleaner or equivalent. Allow the alcohol or cleaner to air dry.

Important: Care should be taken to prevent window prep #1 (clear) from running into the vision area of the windshield. This primer dries almost instantly, but may stain the viewing area of the window if not applied evenly.

9. Apply Clear Glass Prep #1 with a new dauber to the edge and inner 50 mm (2 in) of the perimeter of the windshield surface and wipe the surface dry with a clean cloth.

Important: Urethane will not bond to the windshield unless Black Primer #2 is applied to the windshield.

10. Shake Black Glass Primer #2 well and apply with a new dauber to the edge and inner 50 mm (2 in) of the windshield surface and allow the surface to dry for approximately 6 to 10 minutes.

Important: 

•	Urethane will not bond to the pinchweld unless Black Primer #3 is applied to the pinchweld.

•	Do Not apply the primer to existing urethane adhesive.

•	The pinchweld should be an original paint or primed surface not an after-market finished painted surface.

11. Shake the Black Pinchweld Primer #3 well and apply with a new dauber to all scratches and bare primer paint on the pinchweld and allow the surface to dry for approximately 10 minutes.



12. Cut a notch in the side of the caulking tip 10 mm (0.38 in) high and 4.5 mm (0.18 in) wide.
13. Apply the windshield urethane adhesive using a caulking gun. Hold the gun perpendicular to the surface.



14. Apply a smooth continuous 4.5 mm (0.18 in) wide and 10 mm (0.38 in) bead of urethane adhesive directly to the windshield opening.



15. Install the windshield in the opening and align to the previously installed masking tape.

•	Hand press the windshield firmly in place.

•	Tape the windshield to the body to minimize movement.

•	Paddle the urethane adhesive as needed.

•	Clean up any urethane adhesive squeezed out from under the window.




16. Adjust the windshield stops to the window.



17. Watertest the windshield immediately.

•	Use a soft spray.

•	Use warm water if available.

•	DO NOT direct a hard stream of high pressure water at the fresh urethane adhesive.

•	Water will accelerate the cure of the urethane adhesive.

18. If leaks are found, apply extra urethane adhesive at the leak points using a plastic paddle and then retest with water.



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



20. Install the windshield weatherstrip. Refer to Weatherstrip Side Retainer Replacement .



21. Install the air intake plenum screen. Refer to Plenum Panel Screens in Body Front End.
