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. Remove the C-pillar, D-pillar and rear quarter trim panels.
2. NOTE: Lubricate the existing urethane adhesive with water to aid the special tool while cutting.
From inside the vehicle, using the special tool, cut the glass starting at the upper C-pillar and work down, across the D-pillar, then across the bottom.
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 urethane has cured. Adequate cure time is specified on the drive away chart for each urethane product as temperatures and humidity vary. Inadequate or incorrect curing can adversely affect retention of the quarter window glass.
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.
2. For a uniform fit, use the 2 alignment pins on the rear quarter window glass to align the rear quarter window glass in the opening.
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 the manufacturer's recommendations.
Using an appropriate tool, trim the urethane adhesive leaving a 1 mm (0.03 in) to 2 mm (0.07 in) base of original equipment urethane on the pinch weld.
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 glass cleaner.
7. CAUTION: Be sure to use the same brand urethane and cure-rate products for adhesive and primer. Do not mix different brands of urethane and primer.
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 the 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 are smoothed into one continuous bead starting and ending at the bottom of the rear quarter window glass opening near the center.
10. CAUTION: When installing urethane-installed glass parts, the vehicle must not be driven until urethane has cured. Adequate cure time is specified on the drive away chart for each urethane product as temperatures and humidity vary. Inadequate or incorrect curing can adversely affect retention of the quarter window glass.
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.
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.
11. Install the C-pillar, D-pillar and rear quarter trim panels.
