Window Glass - Rear: Installation
WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
- Dry fit the rear window glass. Make alignment marks with tape or non-staining grease pencil.
- After the dry-fit alignment, remove the glass from the rear window 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 glass removal.
- If reinstalling the original rear window glass, remove the excess urethane adhesive from the rear window glass leaving a thin layer to bond with the new urethane bead.
- If a new rear window glass is to be installed, attach the new molding to the edge of the glass starting at the top center, then working out, then down the pillars and around the corners.
- Clean the rear window glass with glass cleaner.
- If installing a new rear window glass, apply urethane glass primer according to the manufacturer's instructions. Allow at least 6 minutes to dry.
- Cut the urethane adhesive applicator tip to specification.
- Apply urethane adhesive on top of the existing trimmed urethane adhesive bead on the pinch weld. Make sure that all gaps in the urethane adhesive are smoothed into one continuous bead starting and ending at the bottom of the rear window glass near the center.
- Install the rear window glass aligning it to the marks made previously.
- After the urethane cures, check the rear window glass seal for air or water leaks through the urethane adhesive bead and add urethane adhesive as necessary.
- Connect the rear window glass electrical connectors.
- Install the high-mounted stoplamp. For additional information refer to EXTERIOR LIGHTING article.
- Install the parcel shelf. For additional information, refer to INTERIOR TRIM & ORNAMENTATION article.
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 glass primer manufacturer's recommendations before installation of the glass. Be sure to use the same brand and cure-rate products for the adhesive and primer.
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.
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 with less effort and continuous bead.
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).
CAUTION:
Before positioning the rear window glass, open vehicle windows to prevent the air pressure of closing doors from affecting the adhesive bond.
NOTE:
The urethane adhesive must cure for a minimum of one hour before testing for air or water leaks.
