- Verify all primers and urethane adhesive are within expiration
dates.
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.
- Inspect the following components for the causes of a broken rear window:
• | The flange of the rear window opening |
• | The rear window reveal molding |
- Inspect the following components in order to prevent possible
future damage to the rear window:
• | The flange of the rear window opening |
• | Hardened spot weld sealer |
• | Any obstruction or irregularity in the pinchweld flange |
Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs
or replacements are necessary, refinish the pinchweld flange in order to present
a clean primer only surface. If paint repairs are required, mask
the flange bonding area prior to the application of the color coat
in order to provide a clean primer only surface. Materials
such as BASF DE17®, DuPont 2610®, Sherwin-Williams
PSE 4600 and NP 70 and Martin-Semour 5120 and 5130
products are approved for this application.
- After repairing the opening as indicated, perform the following steps:
- Inspect the condition of the stationary window opening and the
urethane adhesive bead in order to determine which installation method you
will use. Refer to
Short Method Description
or
Extended Method Description
for the guidelines.
5.1. | Remove no more of the window urethane adhesive than necessary
in order to maintain the original shape. This will ensure the proper clearance
between the window and the pinchweld flange of the
opening. |
5.2. | Clean around the inside edge of the inside surface of the window
using GM Glass Cleaner P/N 1050427 or isopropyl alcohol. |
- After repairing the opening as indicated, 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 of the bonding area.
- Allow the primer to dry for approximately 10 minutes. Ensure
that all nicks and scratches are covered.
- Install the new rear window
reveal molding (1). Refer to
Rear Window Reveal Molding Replacement
.
- Start from the center and hand press the rear window reveal molding (1)
onto the rear window (2).
- With the aid of an assistant,
dry fit the stationary window in the opening in order to determine the correct
way to position the stationary window in the opening.
- Use masking tape in order to mark the location of the stationary
window in the opening.
- Slit the masking tape at the top edge of the stationary window.
- With the aid of an assistant
and the suction cups, remove the stationary window.
- Place the rear stationary window on a clean, protected surface.
- If the origianl rear window is being reused, remove all but approximately
2 mm (3/64 in) of the existing urethane adhesive from the rear
window surface, using a utility knife or razor blade scraper.
- Clean the inside surface of the stationary window to which urethane
adhesive will be applied (around the edge of the inside surface) by wiping
with a clean lint free cloth dampened with GM Glass Cleaner P/N 1050427
or equivalent.
Important: Do not remove all traces of the urethane adhesive, but all mounds or
loose pieces should be removed.
- 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.
- Shake the pinchweld primer (black #3) for at least one
minute.
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.
- Use a new dauber to apply the primer to the surface of the pinchweld
flange.
- Allow the primer to dry for approximately 10 minutes.
Important: Use care when applying the stationary window prep (clear #1)
in order to prevent the stationary window preparation from running into the
vision area of the stationary window. This stationary
window prep may stain the viewing area of the
rear window if not applied evenly. This stationary window
prep (clear #1) dries almost instantly.
- If installing a new non
encapsulated window:
22.1. | Use a new dauber, to apply the stationary window prep (clear #1)
to an area approximately 10 to 16 mm (3/8 to 5/8 in) around
the entire perimeter of the stationary glass inner surface (reference
the illustration of the primer/bonding areas). |
22.2. | Apply the stationary window prep (clear #1) to any exposed
edges of the window. |
22.3. | Wipe the primed area immediately with a lint-free cloth. |
22.4. | Shake the glass primer (black #2) for at least one minute. |
- If installing a new encapsulated window:
23.1. | Use a new dauber, to apply the stationary window prep (clear #1)
to an area approximately 10 to 16 mm (3/8 to 5/8 in) around
the entire perimeter of the stationary glass inner surface (reference
the illustration of the primer/bonding areas). The glass must be
installed within 8 hours after applying the primer to the
glass. |
23.2. | The primed surface of the glass must be kept clean. |
23.3. | Allow the glass primer to dry for approximately 10 minutes. |
- Shake the stationary window primer (black #2) for at least
one minute.
- Use a new dauber, in order
to apply the stationary window primer (black #2) to the areas of the
stationary window (1) to which prep (clear #1) was applied.
- Allow the primer to dry for approximately 10 minutes.
- If using the short method,
cut the tip in order to provide an adhesive bead of approximately 6.0 mm
(0.25 in).
- If using the extended method, cut the tip in order to provide
an adhesive bead of approximately 10.5 mm (0.14 in) wide and
10.5 mm (0.14 in) high.
- Use a cartridge-type caulking
gun, apply a smooth continuous bead of new urethane adhesive around the edge
of the stationary window where the primer was applied.
- 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 stationary 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 (2) of the stationary
window (3).
- With the aid of an assistant,
use the suction cups in order to install the stationary window (1)
into the opening.
- Align the tape on the rear window and on the body.
- Press the rear window firmly into place in order to wet-out and
seat the urethane adhesive.
- Tape the rear window in two places 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 at the fresh urethane
adhesive.
- Use a soft spray of warm water in order to immediately water test the
rear window.
- Inspect the rear window for leaks.
- If any leaks are found, use a plastic paddle in order to apply
extra urethane at the leak point.
- Retest the stationary window 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:
41.1. | Partially lower a door window in order to prevent pressure buildups
when closing doors before the urethane adhesive cures. |
41.2. | Do not drive the vehicle until the urethane adhesive is cured.
Refer to the above curing times. |
41.3. | Do not use compressed air in order to dry the urethane adhesive. |
- Connect the rear window
electrical connectors.
- Install the rear quarter trim panels. Refer to
Rear Quarter Trim Panel Replacement
in Interior Trim.
- Install the rear seat back. Refer to
Rear Seat Back Replacement
in Seats.
- Install the rear seat cushion. Refer to
Rear Seat Cushion Replacement
in Seats.
- Remove the protective coverings and tape from the vehicle and
the headliner.
- Close the rear compartment lid.
