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:
- 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.
- Use a new dauber to apply the pinchweld primer (black #3) to
the surface (1) of the bonding area.
- Allow the primer
to dry for approximately 10 minutes. Ensure that all nicks and scratches are
covered.
- Install the lower windshield supports (1) to the cowl panel, if equipped.
- If using extended method, install the spacers and the VIN plate filler
strip.
- Install the reveal molding to the edge of the windshield. If the original
reveal molding is damaged it must be replaced.
- Install a new acoustic strip if needed.
- 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.
