Window Glass - Rear Quarter: Installation

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

Dry fit the rear quarter window glass, making alignment marks with tape or non-staining grease pencil.

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 pinchweld.
Using a clean shop towel, brush or oil-free compressed air, clean the pinch weld area around the existing urethane adhesive. Remove any foreign material or water that may have entered during glass removal.
If installing the original rear quarter window glass, remove the excess urethane adhesive.
Clean the inside of the rear quarter window glass with glass cleaner.

NOTE: If installing a LH rear quarter window on the Escape Hybrid, do not apply urethane glass prep to the polycarbonate vent of the window assembly.

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. For additional information, refer to the MATERIAL CHART .

If installing a new rear window glass, apply glass primer according to manufacturer's instructions. Allow at least 6 minutes to dry.
Cut the urethane adhesive applicator tip to specification.

NOTE: The rear quarter glass must be positioned within 10 minutes of applying the urethane adhesive.

NOTE: Use caution when applying urethane adhesive. Apply to the outside edges of locating pins on the glass surface.

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

Apply a bead of urethane adhesive starting at the bottom and work around to the sides of the rear quarter window glass to specification, making sure there are no gaps in the 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).

NOTE: Before positioning the rear quarter window glass, open vehicle windows to prevent the air pressure of closing doors from affecting the urethane adhesive bond.

Install the rear quarter window glass, aligning it to the marks previously made.

NOTE: The urethane adhesive must cure for a minimum of one hour before testing for air or water leaks.

After the urethane adhesive has cured, check for water leaks and add urethane adhesive where needed.
If necessary, remove excess urethane adhesive from the exterior surface of the quarter window glass.
Install the headliner. For additional information, refer to HEADLINER .
