Tools Required

1. Install the window reveal molding (1) to the window (2).
2. With suction cups and the aid of a helper, dry fit the window to the window panel.
3. Clean the window surface to which the urethane is to be applied with an alcohol dampened cloth. Allow the alcohol surface to air dry.

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.




4. Apply the pinchweld primer #3 (1) to any exposed painted surfaces on the lift window panel.

Primer Bead Specification
Primer bead 25 mm (0.98 in).

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.




5. Apply Clear Glass Prep #1 (2) with a clean dauber to the surface of the window (4) that will contact the urethane area of the panel. Wipe the window dry with a clean lint free cloth.
6. Apply Black Glass Primer #2 with a clean dauber to the surface of the window that will contact the urethane and allow the primer to air dry for 6 to 10 minutes.

Primer Bead Specification
Primer bead 13 mm (0.512 in).

Urethane will not bond to the window unless Black Primer #2 has been applied to the window.

Important: Do not apply Black Primer to the existing urethane on the lift window panel.

8. Install the window to the lift window panel with the aid of a helper.

Use suction cups to position the window.
