Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs
or replacements are required, the pinchweld flange must be refinished in order
to restore the bonding area strength. If paint repairs are required,
mask the flange bonding area prior to applying the color coat in
order to provide a clean primer only surface. Materials such
as BASF DE17®, DuPont 2610®, Sherwin-Williams
PSE 4600 and NP70® and Martin-Semour 5120
and 5130® products are approved for this application.
- After repairing the opening do the following.
- Inspect the condition of the window opening and the urethane
adhesive bead to determine which installation method should be used. Refer
to
Short Method Description
or
Extended Method Description
for guidelines.
- Remove no more of the urethane adhesive from the pinchweld than
necessary in order to maintain the original shape. This will ensure the
proper clearance between the window and the pinchweld flange.
Important: Do not remove all traces of the adhesive. Remove all mounds or loose
pieces of urethane adhesive.
- If the original window is being reused remove all but a thin film of
the existing urethane adhesive from the window surface by using a clean
utility knife or razor blade scraper.
- If the extended method is being used remove all but approximately
2 mm (3/64 in) of the existing bead of urethane adhesive from
the pinchweld flange.
- After repairing the opening, remove all traces of broken glass
from the outer cowl panel, seats, floor and defroster ducts.
- Clean around the edge of the inside surface of the window with
a 50/50 mixture of isopropyl alcohol and water by volume on a
dampened lint free cloth.
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.
- Verify all primers and urethane adhesive are within expiration dates.
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.
Important: Do not apply the (black #3 primer to the existing bead of the
urethane adhesive. Apply only to nicks, scratches or the primed surfaces.
- Shake the pinchweld primer (black #3) for at least 1 minute.
- Use a new dauber to apply the pinchweld primer (black #3)
to the surface (1) of the bonding area on the body only.
- Allow the primer to dry for approximately 10 minutes.
- Install the spacers and
the VIN plate filler strip, if equipped.
Important: Use care when applying prep (clear #1) on the window. This primer
dries almost instantly, and may stain the viewing area of the window if
not applied evenly.
- Use a new dauber in order to apply glass prep (clear #1) 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 glass primed area immediately with a clean lint free cloth.
- Shake the glass primer
(black #2) for at least 1 minute.
26.1. | 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. |
26.2. | The glass primer (black #2) is good up to 8 hours
after applying it to the glass. The primed surface of the glass must be kept
clean. |
26.3. | Allow the glass primer to dry for approximately 10 minutes. |
- If using the short method,
cut the tip of the applicator nozzle in order to provide a bead of 6.0 mm
(1/4 in).
- If using the extended method, cut the applicator nozzle in order
to provide a bead of 12.7 mm (1/2 in) wide and 12.7 mm
(1/2 in) high.
- Use a cartridge type caulking
gun to apply a smooth, continuous bead of urethane adhesive.
- When using the short method, apply the urethane adhesive to the
existing bead of urethane adhesive on the body.
- When using the extended
method, use the edge of the windshield window or the inside edge of the reveal
molding as a guide for the nozzle in order to apply the urethane
adhesive (1) to the inner surface of the windshield window (3).

into place.
- Tape the windshield to the body in order to minimize movement
until the urethane adhesive cures.
- Clean any excess urethane
adhesive from the body.
Important: Do not direct a hard stream of high pressure water to the freshly applied
urethane adhesive.
- Use a soft spray of warm water in order to immediately water test the
windshield window.
- 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.
Caution: Insufficient curing of urethane adhesive may allow unrestrained occupants
to be ejected from the vehicle resulting in personal injury.
• | For the moisture-curing type of urethane adhesive, allow a minimum
of 6 hours at 21°C (70°F) or greater and with at least 30 percent
relative humidity. Allow at least 24 hours for the complete curing
of the urethane adhesive. |
• | For the chemical-curing type of urethane adhesive, allow a minimum
of 1 hour . |
Do NOT physically disturb the repair area until after these minimum
times have elapsed.
- The following conditions must be maintained to properly cure the urethane.
42.1. | Partially lower a door window in order to prevent pressure buildups
