Removal
WARNING: To prevent glass splinters from entering the eyes or cutting hands, wear safety glasses and heavy gloves when cutting the glass from the vehicle. Failure to follow these instructions may result in personal injury.
1. Remove the rear quarter trim panel.
2. Remove the wiring harness brackets.
3. NOTE: Locating tabs need to be cut through in order to remove the rear quarter window glass. The new rear quarter window glass will be equipped with new locating tabs.
Lubricate the urethane adhesive with water to aid the special tool when cutting.
4. Using the special tool, cut the urethane adhesive from the rear quarter window glass starting at the top center, working toward the bottom corners to remove the rear quarter glass.
5. Using a soft brush or vacuum, remove any foreign material or dirt from the pinchweld.
Installation
CAUTION: After installing the urethane installed glass, the vehicle should not be driven until the urethane adhesive has cured. Refer to the drive away chart time for the cure time as temperatures and humidity vary. Inadequate curing of the urethane adhesive will adversely affect the strength of the urethane bond.
1. Dry fit the rear quarter window glass, making alignment marks with tape or non-staining grease pencil.
2. 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.
3. Clean the inside of the rear quarter glass encapsulation rim surface with glass cleaner, making sure the area is clean.
4. 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.
5. Cut the urethane adhesive applicator tip to specification.
6. NOTE: Use either a high-ratio, electric or battery-operated caulk gun that will apply the urethane with less effort and continuous bead.
Use caution when applying urethane adhesive. Apply to the outside edges of the locating tabs on the glass surface. Start at the bottom and work around to the sides of the rear quarter window glass.
7. Install the rear quarter window glass, aligning it to the marks previously made.
8. Install the wiring harness brackets.
9. Install the rear quarter trim panel.
