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 C-pillar trim panel and parcel shelf, and lower the headliner.
2. Disconnect the 2 rear window defrost electrical connectors.
3. 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 window glass window. Start cutting the glass at the top and work toward the corners.
4. Using the special tool, distance the rear window glass from the body.
5. Using the special tool, cut the remaining urethane adhesive and remove the window glass.
6. 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 rear window.
NOTE: For additional material guidelines, refer to the manufacturer's installation information.
1. Dry fit the rear window glass to the existing urethane adhesive bead on the body pinch weld. Align the rear window glass in the opening for a uniform fit.
2. Use a non-permanent pencil to make alignment marks on the rear window glass at the setting blocks and the body to aid in the installation alignment of the rear window glass.
3. Remove the rear 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 pinch weld.
5. If installing the original rear window glass, remove the excess urethane adhesive.
6. Clean the inside of the rear window glass surface with 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 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 window glass near the center.
10. Install the rear 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 rear window.
After the urethane has cured, check the rear window glass seal for air or water leaks through the urethane adhesive bead and add urethane adhesive as necessary.
12. Install the headliner, parcel shelf and C-pillar trim panels.
13. Connect the LH and RH heated rear window electrical connector.
