- 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 window opening |
• | The stationary window reveal molding |
- Inspect for any of the following problems in order to help prevent
future breakage of the 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® and Martin-Semour 5120 and
5130® products are approved for this application.
- After repairing the opening as indicated, perform the following steps:
• | 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. |
• | Remove all traces of broken glass from the vehicle. |
• | Clean around the edge of the inside surface of the stationary
window with a 50/50 mixture of isopropyl alcohol and water by
volume 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, also check
to ensure that all nicks and scratches are covered.
- With the aid of an assistant,
dry fit the stationary window into the opening.
- Install the reveal molding to the edge of the stationary window.
If the original reveal molding is damaged it must be replaced, if
equipped.
- 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 window with
a 50/50 mixture of isopropyl alcohol and water by volume 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 stationary window prep (clear #1)
to the stationary window. This primer dries almost instantly and may stain
the viewing area of the window if not applied evenly.
- If installing a new non encapsulated stationary window:
20.1. | Use a new dauber, to apply the stationary window prep (clear #1)
approximately 10-16 mm (3/8-5/8 in) around the
entire perimeter of the window inner surface. |
20.2. | Apply stationary window prep (clear #1) to any exposed
edges of the window. |
20.3. | Wipe the primed window area immediately with a clean lint free
cloth. |
20.4. | Shake the glass primer (black #2) for at least one minute. |
- If installing a new encapsulated window:
Use a new dauber, in order to apply the window prep (clear #1)
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 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 (2) 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.
- Use a soft spray in order to water test the stationary window
immediately.
- 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 installing the left side stationary window refer

and
Body Side Rear Trim Panel Replacement
in Interior Trim.
- When replacing or installing the right side stationary window
refer to interior trim for removal. Refer to
Body Side Trim Panel Replacement - Right Side
and
Body Side Rear Trim Panel Replacement
in Interior
Trim.
- Remove the protective coverings and tape from the vehicle and
the headliner.
