- 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 stationary
window:
• | The flange of the stationary window opening |
• | The stationary window reveal molding |
- Inspect for any of the following problems in order to help prevent
future breakage of the stationary window:
• | Hardened spot weld sealer |
• | Any other obstruction or irregularity in the pinchweld flange |
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 ®,
or Martin-Semour 5120® and 5130 ® products are
approved for this application.
- After repairing the open as indicated, perform the following steps:
- Inspect the condition of the stationary window opening and the
adhesive bead to determine which installation method should be used.
Refer to
Short Method Description
or to
Extended Method Description
for guidelines.
- Remove no more of the urethane adhesive than necessary in order
to maintain the original shape. This will ensure the proper clearance between
the stationary window and the pinchweld flange.
6.1. | Remove all traces of broken glass from the vehicle. |
6.2. | Clean around the edge of the inside surface of the stationary
window with a 50/50 mixture (by volume) of isopropyl alcohol and water on
a dampened, lint-free cloth. |
- After repairing the opening as indicated, shake the pinchweld
primer (black #3) for at least 1 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 of the bonding area.
- Allow the primer to dry for approximately 10 minutes. Ensure that
all nicks and scratches are covered.
- Install the reveal molding
to the edge of the stationary window. If the original reveal molding is
damaged it must be replaced, if equipped.
- With the aid of an assistant, install the stationary window into
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,
remove the stationary window from the opening.
- Place the stationary window inside up on a clean, protected surface.
Important: Do not remove all traces of the adhesive. Remove all mounds or loose
pieces of urethane adhesive .
- 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.
- Clean around the edge of the inside surface of the stationary
window with a 50/50 mixture (by volume) of isopropyl alcohol and water on
a dampened, lint-free cloth.
Important: Do not apply the (black #3) primer to the existing bead of the
urethane adhesive. Apply the primer only to nicks, scratches or the primed
surfaces.
- 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 glass primer to dry for approximately 10 minutes.
- Allow to air dry.
Important: Use care when applying the prep (clear #1) to the stationary
window. This primer dries almost instantly and may stain the viewing area
of the stationary window if not applied evenly.
- If installing a new, non-encapsulated stationary window:
22.1. | 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 stationary window inner surface. |
22.2. | Apply stationary window prep (clear #1) to any exposed
edges of the stationary window. |
22.3. | Wipe the primed window area immediately with a clean, lint-free
cloth. |
22.4. | Shake the glass primer (black #2) for at least one minute. |
- If installing a new, encapsulated stationary window:
Use a new dauber in order to apply the stationary window prep (clear #2)
to the area approximately 10-16 mm (3/8-5/8 in)
around the entire perimeter of the glass inner surface of the primer/bonding
areas. The primer is good up to 8 hours after applying it to the
glass. The primed surface of the glass must be kept clean.
- 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 10.5 mm (0.14 in)
wide and 10.5 mm (0.14 in) high.
- Use a cartridge type caulking
gun to apply a smooth, continuous bead of new 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 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 of the stationary window (3).
- With the aid of an assistant,
use the suction cups in order to install the stationary window into the opening.
- Align the tape on the stationary window and the body.
- Press the stationary window firmly into place.
- Tape the stationary window 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
rear window.
Inspect the stationary window for leaks.
- If any leaks are found, use a plastic paddle in order to apply
extra urethane at the leak point.
- Retest 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:
38.1. | Partially lower a door stationary window in order to prevent pressure
buildups when closing doors before the urethane adhesive cures. |
38.2. | Do not drive the vehicle until the urethane adhesive is cured.
Refer to the above curing times. |
38.3. | Do not use compressed air in order to dry the urethane adhesive. |
- When replacing or removing the left side stationary window refer
to interior trim for removal. Refer to
Third Pillar Trim Replacement - Left Side
in Interior Trim
or to
Fourth Pillar Trim Replacement - Left Side
in Interior Trim.
- When replacing or removing the right side stationary window refer
to interior trim for removal. Refer to
Third Pillar Trim Replacement - Right Side
in Interior
Trim or to
Fourth Pillar Trim Replacement - Right Side
in Interior Trim.
- Remove the protective coverings and tape from the vehicle and
the headliner.
