Removal Procedure
Caution: When replacing stationary windows, urethane kit GM P/N 12346284 or equivalent
must be used to maintain original installation integrity. Failure to use the
urethane kit will result in poor retention of the windshield which may allow
unrestrained occupants to be ejected from the vehicle resulting in personal
injury.
Caution: When you are working with any type of glass, use approved safety glasses
and gloves to reduce the chance of personal injury.
Tools Required
- Remove the windshield side reveal moldings. Refer to
Windshield Side Reveal Molding Replacement
.
- Cut the outer lip of the upper reveal molding off with a urethane
razor knife or equivalent to allow access to the body pinchweld.
- Remove the windshield wiper arms. Refer to
Windshield Wiper Arm Replacement
.
- Remove the air inlet grille from the cowl area. Refer to
Air Inlet Grille Panel Replacement
.
- Remove the rearview mirror. Refer to
Inside Rearview Mirror Replacement
.
- Remove the windshield garnish molding. Refer to
Windshield Pillar Garnish Molding Replacement
.
- Mask off the area around the windshield to protect the painted
surface.
Caution: If broken glass falls into the defroster outlets, it can be blown into
the passenger compartment and cause personal injury.
- Place a protective covering over the top of the instrument panel making
sure the defroster vents are covered to prevent foreign objects from entering
the outlets.
- Working outside the vehicle, cut out the windshield using a J 24402-A
.
- It may be necessary to use a wire type cutting
tool to cut around the lower corners of the windshield to clear the
fenders.
- Remove the windshield with the aid of a helper
and the suction cups from the J 36863
.
- Remove all of the urethane from the body pinchweld using a sharp
scraping tool.
- Remove all of the urethane from the windshield using a sharp scraping
tool.
Cleaning Procedure
- Clean all loose urethane and debris using a vacuum.
- Wipe the body pinchweld flange with a clean dry cloth.
Important: Ensure that the window opening is properly prepared before window installation.
- If there is corrosion on the pinchweld or if sheet metal repairs
or replacements are required, the pinchweld flange must be refinished to present
a PRIMER ONLY surface.
- If paint repairs are required, mask the flange bonding area (prior
to applying the color coat) to provide a PRIMER ONLY surface.
- The appropriate materials for these primer applications are typically
two component, catalyzed products such as BASF DE 17, DUPONT 2610, PPG DP90
(or equivalent) applied by following the manufactures directions
for mix, application and drying times.
- After repairing the window opening as indicated, shake the pinchweld
primer #3 (black) well, and using a new dauber, apply the primer to the bonding
area of the pinchweld. Allow to dry for 10 minutes.
Installation Procedure
- Install the upper reveal molding on the windshield.
Refer to
Windshield Upper Reveal Molding Replacement
.
- Dry fit the window into the body opening to determine
the correct position by:
• | Dry fit the window into the body opening to determine the correct
position by: |
• | Positioning the window into the opening. |
• | Using masking tape, mark the location of the window into the opening
on at least one horizontal edge (1) and one vertical edge (2) of the window. |
• | Slit the masking tape at the window edges and remove the window
from the body opening. |
• | Place the windshield on a clean protected work surface with the
inside of the windshield facing up. |
Notice: Failure to install the acoustic strip could cause windshield breakage.
- Install the acoustic strip (2) with a 2 mm or less gap (3) to the dashed
line (1) painted on the windshield.
Important: The application of primers is important as they act as the agent that
will bond the urethane to the windshield. Be sure to use the specified primer
for each application listed below for proper adhesion.
- Shake the pinchweld primer #3 (black) well and apply it to any exposed
painted surfaces (or scratches to any bare metal) on the body pinchweld
flange. Allow to dry for 10 minutes.
- Care should be taken to prevent the glass prep #1 (clear) from
running into the vision area of the window. This primer dries almost instantly,
but may stain the viewing area of the window if not applied evenly.
- Using a new dauber, apply the glass prep #1 (clear)
around the entire perimeter of the inner surface and any exposed edges
of the window. Wipe the surface dry with a clean cloth.
- Shake the primer #2 (black) well and using a
new dauber apply the primer around the edges of the windshield, 15 mm
(5/8 in) inboard on the inner surface, over the same
area that the glass prep #1 (clear) was applied.
- Allow the primer to dry for 10 minutes.
- Install a tube of urethane in the J 24811
.
- Apply the urethane adhesive to the windshield.
- Apply a bead (1) 8 mm (5/6 in) height (6) and 14 mm
(9/16 in) wide (5).
- Install the windshield with the aid of a helper
and the suction cups from the J 36863
.
- Press firmly on the windshield to wet-out and set the urethane
adhesive.
- Tape the windshield at the top using four pieces of tape.
- Watertest the windshield immediately using a soft spray. Warm
or hot water is preferred to accelerate the curing of the adhesive. DO NOT
direct a hard stream of high pressure water at the fresh urethane
adhesive.
- If a leak is detected,
apply urethane adhesive to the leak point and 127 mm (5 in) on
both sides of the leak point using a flat bladed tool.
Important: The following steps must be taken before completing the installation
procedure.
• | Allow the vehicle to remain at room temperature 22°C (72°F)
at 30% relative humidity for a minimum of 6 hours. |
• | Lower the door windows partially to prevent pressure build up
when closing the doors prior to the urethane adhesive curing. |
• | DO NOT DRIVE THE VEHICLE until the urethane is cured a (minimum
6 hours at room temperature). |
• | DO NOT USE COMPRESSED AIR to dry the urethane adhesive. |
- Remove the masking tape from the windshield after
the urethane has cured.
