Removal Procedure
Important: Before cutting out a stationary window, apply a double layer of masking
tape around the perimeter of the painted surfaces and inner trim around the
window.
- Open the rear doors.
- Remove the window molding (if equipped).
- When replacing or removing the left or right sides of the in interior
trim, refer to
Third Pillar Trim Replacement
in Interior Trim.
Caution: If broken glass falls into the defroster outlets, it can be blown into
the passenger compartment and cause personal injury.
- Remove the body side trim panels. Refer to
Rear Quarter Trim Panel Replacement
in Trim Panel Replacement.
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.
Important: Keep the cutting edge of the tool against the stationary window when
removing the stationary window. This will allow the urethane adhesive to
be separated from the stationary window. Leave a base of urethane
on the pinchweld flange. The only suitable lubrication is clear
water.
- Use the J 24402-A
or J 39032
in order to remove the stationary
window. Do this from inside the vehicle to protect the outer surface of the
paint.
- If the original reveal molding on the quarter window is damaged
it must be replaced.
- With the aid of an assistant,
use the suction cups to remove the window from the opening.
Installation Procedure
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 quarter
window :
• | The flange of the quarter window opening |
• | The quarter window reveal molding |
- Inspect for any of the following problems in order to help prevent
future breakage of the quarter 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:
3.1. | Inspect the condition of the quarter window opening and the adhesive
bead to determine which installation method should be used. Refer to Short
Method Description or Extended Method Description for guidelines. |
3.2. | Remove no more of the urethane adhesive from the pinchweld than
necessary in order to maintain the original shape. This wil ensure
the proper clearance between the quarter window and the pinchweld flange. |
3.3. | Remove all traces of broken glass from the outer cowl panel, seats,
floor and defroster ducts. |
3.4. | Clean around the edge of the inside surface of the quarter window
with a 50/50 mixture of isopropyl alcohol and water by volume on a
dampened lint free cloth. |
- 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.
- 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 quarter window in the
opening in order to determine the correct way to position the quarter
window in the opening.
- Use masking tape in order to mark the location of the quarter
window in the opening.
- Slit the masking tape at the top edge of the quarter window.
- With the aid of assistant and using suction cups remove the quarter
window from the opening.
- Place the quarter window inside up on a clean, protected surface.
- If the original quarter window is being reused remove all but
a thin film of the existing urethane adhesive from the quarter window surface
by using a clean 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 (3/64 in) of the existing bead of adhesive from the pinchweld
flange.
- Clean around the edge of the inside surface of the quarter 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 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.
Important: Use care when applying prep (clear #1) on the quarter window.
This primer dries almost instantly, and may stain the viewing area of the
quarter window if not applied evenly.
- Use a new dauber in order to apply glass prep (clear #1) to the
area approximately 10 mm to l6 mm (3/8 in to 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 one minute.
- 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.
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.
- 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 quarter 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 quarter window (3).
If applying urethane adhesive to the inside edge of the quarter window
reveal molding (1) use the quarter window reveal molding as a guide for the
nozzle.
- With the aid of an assistant, use the suction cups in order to
install the quarter window into the opening.
- Align the tape lines on the quarter window and the body.
- Press the quarter window firmly into place.
- Tape the quarter 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
quarter window.
- Inspect the quarter 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 quarter window for leaks.
- The following conditions must be maintained to properly cure the
urethane adhesive:
38.1. | Allow the vehicle to remain at room temperature (21°C or 70°F)
at 30 percent relative humidity. |
| Caution: At least 24 hours are required for complete curing of repair
material. The repair area should not be physically distrubed until after that
time. Insufficient curing of urethane adhesive may allow unrestrained occupants
to be ejected from the vehicle resulting in personal injury.
|
38.2. | Allow a minimum of 6 hours for the moisture curing urethane
adhesive. |
38.3. | Allow a minimum of 1 hour to 1 1/2 hours for the chemical
curing urethane adhesive. |
38.4. | Partially lower a door window in order to prevent pressure buildups
when closing doors before the urethane adhesive cures. |
