Caution: When working with any type of glass or sheet metal with exposed or rough
edges, wear approved safety glasses and gloves in order to reduce
the chance of personal injury.
- Use safety glasses and
gloves.
Important: Skip Step 7 if the rear window is not going to be replaced. The
rear window reveal molding is part of the rear window on this vehicle.
The stationary window reveal molding retains the urethane in the cavity
between the body and the opening. If the stationary window reveal molding
is damaged, or the reveal molding is cut away in order to remove the
rear window from the outside with the J 24402-A
, the rear window will need to be replaced.
Important: Keep the cutting edge of the tool against the rear window. This will
allow the urethane adhesive to be separated from the rear window. Leave
a base of urethane on the pinchweld flange. The only suitable lubrication
is clear water.
- Using a sharp utility knife, make a preliminary cut around the perimeter
of the rear window, cut as close to edge of the rear window as possible.
- Use the J 39032
in order to cut the stationary window from the pinchweld flange. Do this
from inside the vehicle in order to protect the outer paint surface,
and the reveal molding.
When cutting the urethane, apply
a spray mist of water around the surface to aid in the removal. keep the
blade on the knife as close to the rear window as possible in order to
leave a base of urethane on the pinchweld flange
- With the aid of an assistant,
use the suction cups in order to lift the rear window from the opening.
- 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 for any of the following components for the causes
of a broken rear window:
• | The flange of the rear window opening |
• | The rear window reveal molding |
- Inspect for any of the following conditions in order to prevent
future breakage of the rear 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 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 NP70 ® 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 rear 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.
- Remove all traces of broken glass from the vehicle.
- Clean around the edge of the inside surface of the rear 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 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 (1) of the bonding
area on the body only.
- Allow the primer to dry for approximately 10 minutes, Ensure
that all nicks and scratches are covered.
- With the aid of an assistant,
dry fit the rear window in the opening in order to determine the correct
way to position the rear window in the opening.
- Use masking tape in order to mark the location of the rear window
in the opening.
- Slit the masking tape at the edge of the rear window.
- With the aid of an assistant and the suction cups, remove the
rear window from the opening.
- Place the rear window inside up on a clean, protected surface.
- If the original window is to be reused, remove all but a thin
film, approximately 2 mm, 5/64, of the existing urethane adhesive
from the window surface by using utility knife or razor blade scraper.
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 (5/64 in) of the existing bead of adhesive from
the pinchweld flange.
- Clean around the edge of the inside surface of the rear 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 pinchweld primer to dry for approximately 10
minutes.
- If the extended method is being performed, do the following:
Important: Use care when applying the glass prep (clear #1) to the rear
window. This primer dries almost instantly, and may stain the viewing area
of the rear window if not applied evenly.
22.1. | Use a new dauber in order to apply glass prep (#3 clear)
to an area approximately 10 mm to 16 mm (3/8 in to
5/8 in) around the entire perimeter of the rear glass inner surface.
The window must be installed within 8 hours, after applying the
primer to the glass. |
22.2. | The primed surface of the window must be kept clean. |
22.3. | Allow the glass primer to dry for approximately 10 minutes. |
22.4. | Shake the rear window primer (black #2) for at least one
minute. |
- Use a new dauber, in
order to apply the rear glass primer (black #2) to the areas of the
rear window (1) to which glass prep (clear #1) was applied (2).
- Allow the 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 (1/4 in). |
25.2. | If using the extended method, cut the tip of the applicator nozzle
in order to provide a bead 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 around the edge
of the rear 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, apply the urethane adhesive (1) using the edge of the rear
window or the inside edge of the reveal molding as a guide for the nozzle
in order to apply the urethane adhesive to the inner surface of the rear
window.
- With the aid of an assistant,
use rubber suction cups in order to install the rear window in 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 place 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 applied
urethane adhesive.
- Use a soft spray of warm water in order to immediately water test the
rear window.
Using warm water is preferred in order to accelerate
the curing of the urethane adhesive.
- Inspect the rear window for leaks.
- If any leaks are found, use a plastic paddle in order to apply
extra urethane adhesive at the leak point.
- Retest the rear 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:
• | Partially lower a door window in order to prevent pressure buildups
when closing doors before the urethane adhesive cures. |
• | Do not drive the vehicle until the urethane adhesive is cured. |
• | Do not use compressed air in order to dry the urethane adhesive. |
