Window Glass - Rear: Installation
WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
- Dry-fit the rear window glass on the existing urethane bead on the pinch weld.
- Position the rear window glass on the pinch weld.
- Center the rear window glass in the opening.
- Adjust the rear window glass stop blocks (if equipped) as needed for best fit.
- Make alignment marks with tape or non-staining grease pencil (preferably at the glass stop blocks) on the rear window glass and the body.
- After the dry-fit alignment, remove the rear window glass and molding assembly from the windshield opening and place on a stable work surface with the interior side of the glass facing up.
- Using an appropriate tool, trim the urethane adhesive leaving a 1-2 mm (0.04-0.08 in) base of original equipment urethane on the pinch weld.
- Using a clean shop towel, brush or oil-free compressed air, clean the pinch weld area around the existing urethane. Remove any foreign material or water that may have entered during rear window glass removal.
- If reinstalling the original rear window glass, remove the urethane adhesive from the rear window glass leaving a thin layer to bond with the new urethane bead.
- If installing a new rear window glass, clean the inside of the glass surface with glass cleaner.
- Make sure to thoroughly clean the surface of the blackened border area where the urethane adhesive will be applied.
- If installing a new rear window glass, apply urethane glass primer according to manufacturer's instructions. Allow at least 6 minutes to dry.
- Cut the applicator tip to specification. This will produce a triangular bead during application.
- 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.
- Using the alignment marks made previously, position the rear window glass on the pinch weld.
- 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.
- Connect the 2 heated rear window electrical connectors.
- Install the quarter trim panels and parcel shelf. For additional information, refer to INTERIOR TRIM AND ORNAMENTATION .
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. For minor scratches or exposed metal on the pinch weld, see the manufacturer's recommendations.
NOTE:
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.
NOTE:
The rear window glass must be positioned within 10 minutes of applying the urethane adhesive.
NOTE:
Use either a high-ratio, electric or battery-operated caulk gun that applies the urethane adhesive with less effort and a continuous bead.
CAUTION:
Before positioning the windshield glass, open vehicle windows to prevent the air pressure of closing doors from affecting the adhesive bond.
WARNING:
Do not drive vehicle until the urethane adhesive seal has cured. Follow urethane adhesive manufacturer's curing directions. Inadequate or incorrect curing of the urethane adhesive seal will adversely affect glass retention. Failure to follow these instructions may result in serious injury to vehicle occupant(s).
NOTE:
The urethane adhesive must cure for a minimum of one hour before testing for air or water leaks.
