Installation

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 (if equipped) and the body to aid in the installation alignment of the rear window glass.

3. Remove the rear window glass 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 mm to 2 mm (0.04 in to 0.08 in) base of original equipment urethane adhesive on the pinch weld.

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

6. If installing the original rear window glass, remove the excess urethane adhesive.

7. Clean the inside of the rear window glass 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 rear window glass, 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 bottom of the rear window opening near the center, making sure there are no gaps in the bead.

11. Install the rear window glass on the vehicle aligning it with the markings made previously.

12.  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.

    After the urethane adhesive has cured, check the rear window glass seal for air or water leaks through the urethane adhesive bead and add urethane adhesive as necessary.

13. Connect the 2 rear window defrost electrical connectors.

14. Install the liftgate window moulding. For additional information, refer to Section 501-08 .
