in Washers and Wipers.
- Mark the location of the
lower windshield supports with a grease pencil or tape.
- Remove the lower windshield supports.
- Remove the rearview mirror.
Refer to
Inside Rearview Mirror Replacement
- Disconnect the windshield antenna lead connection (if equipped).
Caution: If broken glass falls into the defroster outlets, it can be blown into
the passenger compartment and cause personal injury.
- Tape over the defroster outlets.
- Cover the vehicle interior to protect the interior from broken
glass.
- Apply tape to the painted surfaces around the windshield in order
to prevent paint damage.
- Remove the windshield
weather-strip. Refer to
Weatherstrip Replacement
.
- Remove the windshield
side reveal moldings. Refer to
Windshield Side Reveal Molding Replacement
.
- Remove the windshield
side garnish moldings.
Pull the molding with its retainers from the windshield frame.
- Remove the 4 rearmost
screws attaching the top of the fender to the wheelhouse.
- Reposition the fender for tool access.
- Tape or otherwise protect
the fender from the cutting tool.
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 windshield when removing
the windshield. This will allow the urethane adhesive to be separated from
the windshield. Leave a base of urethane on the pinchweld flange. The only
suitable lubrication is clear water.
- Cut out the windshield useJ 24402-A
J 39032
cold knife, to remove the windshield.
- Remove the windshield
from the vehicle with the aid of an assistant.
- Inspect the following components for the causes of a broken windshield:
• | The flange of the windshield opening |
• | The windshield reveal molding |
- Inspect for any of the following problems in order to help prevent
future breakage of the windshield:
• | 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:
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.
After repairing the opening as indicated, perform the
following:
- 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.
- Install the lower windshield
supports (1) to the cowl panel, if equipped.
- If using extended method,
install the spacers and the VIN plate filler strip.
- Install the reveal molding
to the edge of the windshield. If the original reveal molding is damaged
it must be replaced.
- Install a new acoustic strip if needed.
- If using extended method,
install the spacers and the VIN plate filler strip.
Inspect the acoustic strip on the dash panel and replace if necessary.
- With the aid of an assistant, dry fit the windshield in the opening
in order to determine the correct way to position the windshield in the
opening.
- Carefully inspect the windshield overlap at the body pinch-weld
and the retaining flanges all the way around the body opening.
Specifications
The minimum overlap should be 5.0 mm (0.19 in).
- Mark the windshield position
at the following locations using masking tape.
- Install the windshield
supports if using the extended method.
Press the supports firmly onto the panel.
- Place the windshield on the lower supports (1).
- With the aid of an assistant,
use the suction cups in order to install the windshield window into the opening.
- Align the tape (1)
lines on the windshield and the body.
- Press the windshield firmly into place.
- Tape the windshield 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
windshield window.
- Inspect the windshield for leaks.
- If any leaks are found, use a plastic paddle in order to apply
extra urethane adhesive at the leak point.
- Retest the windshield for leaks.
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.
- The following conditions must be maintained to properly cure the urethane:
16.1. | Allow the vehicle to remain at room temperature (21°C or 70°F)
at 30 percent relative humidity. |
16.2. | Allow a minimum of 6 hours for the moisture curing urethane
adhesive. |
16.3. | Allow a minimum of 1 hour to 1 1/2 hours for the chemical
curing urethane adhesive. |
16.4. | Partially lower a door window in order to prevent pressure buildups
when closing doors before the urethane adhesive cures. |
16.5. | Do not drive the vehicle until the urethane adhesive is fully
cured. Refer to the above curing times. |
16.6. | Do not use compressed air in order to dry the urethane adhesive. |
- Cut the tape used to mark
the location of the windshield.
- Remove the windshield
from the body opening.
- Install the windshield
side reveal moldings. Refer to
Windshield Side Reveal Molding Replacement
.
- Install the windshield
weather-strip. Refer to
Weatherstrip Replacement
.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the fender
mounting screws.
Tighten
Tighten the fender upper flange screws to 1.9 N·m (17 lb in).
- Install the air intake
plenum screen. Refer to
Air Inlet Screen Replacement
in Washers and Wipers.
- Install the plenum to hood seal. Refer to
Hood Rear Seal Replacement
in Body Front End.
- Install the windshield wiper arms and washer hoses. Refer to
Windshield Wiper Arm Replacement
in Washers and Wipers.
- Install the windshield
side garnish moldings.
- Install the inside rearview
mirror.
Tighten
Tighten the rearview mirror mount tension screw to 1.5 N·m
(13 lb in).
- Connect the mirror electrical connector.
- Connect the windshield antenna lead connection (if equipped).
- Leave the windows open to avoid causing pressure when closing
the doors. Air pressure could cause a leak in the urethane adhesive.
- Close the hood.
- Install the roof lift
off panel (coupe) or raise and close the folding top (convertible).
- Allow the windshield urethane adhesive to cure.
