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.
- 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 primed (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.
- Install the spacers and
the VIN plate filler strip if using the extended method.
- Install the reveal molding
to the edge of the windshield. If the original reveal molding is damaged replace
the molding.
- Install a new acoustic strip if needed.
- With the aid of an assistant,
determine the correct way to position the windshield in the opening.
- Use masking tape (1)
in order to mark the location of the windshield in the opening.
- Slit the masking tape at the top edge of the windshield.
- Remove the windshield from the opening.
- Place the windshield inside up on a clean, protected surface.
- If the original windshield is being reused remove all but a thin
film of the existing urethane adhesive from the windshield surface by using
a clean utility knife or razor blade scraper.
- Clean around the edge of the inside surface of the windshield
with a 50/50 mixture of isopropyl alcohol and water by volume on a dampened
lint free cloth.
- If the extended method is being used remove all but approximately
2 mm (3/64 in) of the existing bead of adhesive from the pinchweld
flange.
Important: Do not remove all traces of the adhesive. Remove all mounds or loose
pieces of urethane adhesive.
- Shake the pinchweld primer (black #3) for at least one minute.
- Use a new dauber to apply the primer to the surface of the pinchweld
flange.
- Allow the pinchweld primer to dry for approximately 10
minutes.
Important: Use care when applying the glass prep (clear #1) in order to
prevent the windshield prep from running into the vision area of the windshield.
This primer dries almost instantly, and may stain the viewing area of the
windshield if not applied evenly.
- Use a new dauber in order to apply glass prep (clear #3) to the
area approximately 10-16 mm (3/8-5/8 in) around
the entire perimeter of the window inner surface.
- Apply a second coat of the glass prep number (clear #1)
to the same area of the glass.
- Wipe the primed glass area immediately with a clean lint free
cloth.
- Shake the glass primer (black #2) for at least one minute.
- Use a new dauber in order
to apply the glass primer (black #2) to the same areas (2) that
glass prep (clear #1) was applied.
The glass must be installed within 8 hours after applying the
primer to the glass. The primed surface of the glass must be kept clean.
- Allow the glass primer to dry for approximately 10 minutes.
- Cut the tip of the applicator
nozzle as follows:
| 25.1. | If using the short method, cut the tip of the applicator nozzle
in order to provide a bead of 6.0 mm (¼ in). |
| 25.2. | If using the extended method, cut the applicator nozzle in order
to provide a bead of 12.7 mm (½ in) wide and 12.7 mm
(½ in) high. |
- Use a cartridge type caulking
gun to apply a smooth, continuous bead of urethane adhesive.
- If reusing the original glass apply the new urethane adhesive
on the top of the fresh trimmed urethane adhesive.
- When using the extended
method do the following:
If installing a new glass (3) apply the urethane adhesive (2)
to the freshly primed pinchweld flange.
If applying urethane adhesive to the inside edge of the windshield reveal
molding (1) use the windshield reveal molding as a guide for the nozzle.
- Use suction cups, along
with the aid of an assistant to install the windshield into the opening.
- Place the windshield on the lower supports (1).
- Align the tape lines (1)
on the windshield and the body.
- Press the windshield (2) firmly into place.
- Tape the windshield to the body in order to minimize movement.
- Clean any excess urethane adhesive from the body.
- Use a soft spray in order
to watertest the windshield immediately.
Using warm water is preferred in order to accelerate the curing of the
urethane adhesive.
- Do not direct a hard stream of high pressure water at the freshly
applied urethane adhesive.
- Inspect the windshield for leaks.
- If any leaks are found, use a plastic paddle in order to apply
extra urethane adhesive at the leak point.
- Retest the windshield for leaks.
- Maintain the following conditions in order to properly cure the
urethane:
| | 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.
|
| 40.1. | Allow the vehicle to remain at room temperature of 21°C (70°F)
at 30 percent relative humidity. |
| 40.2. | Allow a minimum of 6 hours for the moisture curing urethane
adhesive. |
| 40.3. | Allow a minimum of 1-1½ hours for the chemical
curing urethane adhesive. |
| 40.4. | Partially lower a door window in order to prevent pressure buildups
when closing doors before the urethane adhesive cures. |
| 40.5. | Do not drive the vehicle until the urethane adhesive is fully
cured. |
| 40.6. | Do not use compressed air in order to dry the urethane adhesive. |
