Removal

1.  WARNING: Wear eye and ear protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.

    WARNING: Wear protective gloves when handling components or parts that have pointed or sharp edges. Failure to follow this instruction may result in serious personal injury.

   NOTE: Lubricate the existing urethane adhesive with water to aid the Pneumatic Knife with Offset Blade while cutting.

   Using the Pneumatic Knife with Offset Blade, cut the urethane adhesive from the roof glass panel.
   • Begin cutting at the front center, work toward the front corners.
   • Continue working around toward the rear corners.

2. Using the Pneumatic Knife with Offset Blade, cut the remaining urethane adhesive and remove the roof glass panel.

Installation

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

1. Dry fit the roof glass panel to the existing urethane adhesive bead on the body pinch weld. Align the roof glass panel in the opening for a uniform fit.

2. Use a non-permanent pencil to make alignment marks on the roof glass panel and the body to aid in the installation alignment of the roof glass panel.

3. Remove the roof glass panel and place on a stable surface.

4.  WARNING: Repair any corrosion found on the pinch weld. The pinch weld is a structural component of the vehicle. Corrosion left unrepaired may reduce the structural integrity of the vehicle. Failure to follow this instruction may result in serious injury to vehicle occupant(s).

   NOTE: Avoid scratching the pinch weld. Repair all minor scratches or exposed metal on the pinch weld following manufacturer's instructions. Use the same brand pinch weld primer, glass primer and urethane adhesive.

   Using an appropriate tool, trim the urethane adhesive leaving a 1-2 mm (0.04-0.08 in) base of original equipment urethane adhesive on the pinchweld.

5. Using a soft brush or vacuum, remove any dirt or foreign material from the pinch weld.

6. If installing the original roof glass panel, remove the excess urethane adhesive.

7. Clean the inside of the roof glass panel surface with glass cleaner.

8. NOTE: Be sure to use the same brand and cure-rate products for the urethane adhesive and glass primer. Do not mix different brands of urethane adhesive and glass primer. Refer to the Material Chart in this procedure.

   If installing a new roof glass panel, apply glass primer according to manufacturer's instructions. Allow at least 6 minutes to dry.

9. Cut the urethane adhesive applicator tip to specification.

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

    Apply urethane adhesive on top of the existing trimmed urethane adhesive bead on the pinch weld, starting and ending at the rear of the roof opening near the center, making sure there are no gaps in the bead.

11.  WARNING: Improper curing of the urethane adhesive may adversely affect glass retention, which is important for restraint system performance during a crash. Carefully follow the urethane adhesive manufacturer's curing instructions. Do not drive the vehicle until the urethane adhesive seal has cured. Failure to follow these instructions may result in serious injury to vehicle occupant(s) during a crash.

    Install the roof glass panel on the vehicle aligning it with the markings made previously.
    • Work the roof glass panel down using only vertical pressure.

12. After the urethane adhesive has cured, clean the interior and exterior roof glass panel with glass cleaner.
