Removal
WARNING: To prevent glass splinters from entering eyes or cutting hands, wear safety glasses and heavy gloves when cutting glass from the vehicle.
1. Remove the parcel shelf, C-pillar and D-pillar trim panels.
2. NOTE: Lubricate the existing urethane adhesive with water to aid the special tool while cutting.
Using the special tool, place the flat side of the knife against the rear quarter glass window. Start cutting the glass at the middle of the D-pillar, and work toward the roof.
3. Remove the rear quarter window glass.
4. Using a soft brush or vacuum, remove any dirt or foreign material from the pinch weld.
Installation
CAUTION: When installing urethane-installed glass parts, the vehicle must not be driven until the urethane has cured. Adequate cure time is specified on the drive away chart for each urethane product as the temperatures and humidity vary. Inadequate or incorrect curing can adversely affect the retention of the windshield.
NOTE: For additional material guidelines, refer to the manufacturer's installation information.
1. Dry fit the rear quarter window glass to the existing urethane adhesive bead on the body pinch weld. Align the rear quarter window glass in the opening for a uniform fit.
2. Use a non-permanent pencil to make alignment marks on the rear quarter window glass at the setting blocks and the body to aid in the installation alignment of the rear quarter window glass.
3. Remove the rear quarter window glass.
4. NOTE: Avoid scratching the pinch weld. For minor scratches or exposed metal on the pinch weld, see manufacturer's recommendations.
Using an appropriate tool, trim the urethane adhesive leaving a 1 mm to 2 mm base of original equipment urethane on the pinchweld.
5. If installing the original rear quarter window glass, remove the excess urethane adhesive.
6. Clean the inside of the rear quarter window glass surface with an alcohol-free glass cleaner.
7. CAUTION: Be sure to use the same brand and cure-rate products for the adhesive and primer. Do not mix different brands of urethane and primer. Refer to the Material Chart in this procedure.
NOTE: Sika uses the same black primer for the glass and pinch weld area.
If installing a new rear quarter window glass, apply urethane glass primer according to manufacturer's instructions. Allow at least 6 minutes to dry.
8. Cut the urethane adhesive applicator tip to specification.
9. NOTE: Use either a high-ratio, electric or battery-operated caulk gun that will apply the urethane with less effort and continuous bead.
Apply urethane adhesive on top of the existing trimmed urethane adhesive bead on the pinch weld. Make sure that all gaps in the urethane adhesive are smoothed into one continuous bead starting and ending at the bottom of the rear quarter window glass opening near the center.
10. NOTE: Before the urethane has set, partially lower the windows to prevent the glass from being pushed out of position when a door is closed.
Install the rear quarter window glass on the vehicle aligning it with the markings made previously.
11. CAUTION: When installing urethane-installed glass parts, the vehicle must not be driven until the urethane has cured. Adequate cure time is specified on the drive away chart for each urethane product as the temperatures and humidity vary. Inadequate or incorrect curing can adversely affect the retention of the windshield.
After the urethane has cured, check the rear quarter window glass seal for air or water leaks through the urethane adhesive bead and add urethane adhesive as necessary.
12. Install the parcel shelf, C-pillar and D-pillar trim panels.
