Removal

WARNING: To prevent glass splinters from entering eyes or cutting hands, wear safety glasses and heavy gloves when cutting glass from the vehicle. Failure to follow these instructions may result in personal injury.

1. Disconnect the 2 heated rear window electrical connectors.

2. CAUTION: Care must be taken to prevent scratching the pinch weld.

NOTE: Lubricate the existing urethane adhesive with water to aid the tool while cutting.

Using an appropriate tool (with the luggage compartment lid open approximately 45 degrees), starting at the bottom outboard corner of the rear window glass, cut the urethane adhesive from the glass.

3. Remove the rear window glass.
4. Using a soft brush or vacuum, clean the pinch weld.

Installation

CAUTION: When installing the urethane installed glass parts, the vehicle must not be driven until the urethane adhesive has cured. Adequate cure time is specified on the drive away chart for each urethane product as the temperature and humidity vary. Inadequate or incorrect curing can adversely affect the retention of the rear window glass.

NOTE: For additional material guidelines, refer to the manufacturer's installation information.

1. Dry-fit the rear window glass by centering it side-to-side and by adjusting the setting blocks (if equipped) to get the correct position of the part top-to-bottom. Make alignment marks with tape or non-staining grease pencil on both the glass and the vehicle body.
2. Remove the rear window glass.







3. NOTE: Avoid scratching the pinch weld. For minor scratches or exposed metal on the pinch weld see manufacturer's recommendations.

Trim the urethane with an appropriate tool leaving a 1 mm to 2 mm base of Original Equipment urethane on the pinchweld.

4. If reinstalling the original rear window glass, remove the urethane adhesive from the rear window glass.
5. If installing a new rear window glass, clean the inside of the glass surface with glass cleaner to make sure the ceramic-coated area is clean.

6. 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.







7. Cut the applicator tip to specification.







8. NOTE: Use either a high-ratio, electric or battery-operated caulk gun that applies the urethane adhesive with less effort and a continuous bead.

Apply a bead of urethane adhesive to the pinch weld. Make sure that all gaps in the urethane adhesive are smoothed into one continuous bead, starting at the bottom of the rear window glass near the center.

9. CAUTION: Open a window to prevent the rear window glass from being pushed out by air pressure when the door is closed.

Using the alignment marks install the rear window glass.

10. 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 glass.

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.

11. Connect the 2 heated rear window electrical connectors.
