Removal
WARNING: To prevent glass splinters from entering the eyes or cutting hands, wear safety glasses and heavy gloves when cutting the glass from the vehicle. Failure to follow these instructions may result in personal injury.
1. Remove the rear quarter trim panel.
2. Remove the wiring harness brackets.
3. NOTE: Locating tabs need to be cut through in order to remove the rear quarter window glass. The new rear quarter window glass will be equipped with new locating tabs.
Lubricate the urethane adhesive with water to aid the special tool when cutting.
4. Using the special tool, cut the urethane adhesive from the rear quarter window glass starting at the top center, working toward the bottom corners to remove the rear quarter glass.
5. Using a soft brush or vacuum, remove any foreign material or dirt from the pinch weld.
Installation
CAUTION: After installing the urethane installed glass, the vehicle should not be driven until the urethane adhesive has cured. For Essex 400-HV, the curing time at temperatures above 13°C (55°F) and relative humidity above 50% is 12-24 hours, refer to the Essex drive away chart time for the cure time as temperatures and humidity vary. Inadequate curing of the urethane adhesive will adversely affect the strength of the urethane bond.
1. Dry fit the rear quarter window glass, making alignment marks with tape or non-staining grease pencil.
2. CAUTION: Do not scratch the pinch weld area.
Trim the remaining urethane adhesive on the pinch weld to within specification. The existing urethane adhesive surface should be smooth and free of cuts and contamination.
3. CAUTION: Use caution when applying Essex U-413. Apply a light amount of primer. Too much primer will run and damage the painted surface.
Use a wool applicator to apply Essex U-413 to any exposed metal on the pinch weld. Allow 6-10 minutes to dry.
4. Clean the inside of the rear quarter glass encapsulation rim surface with alcohol-free cleaner, making sure the area is clean.
5. Wipe off the glass prep immediately after each application because it flash dries. Apply Essex U-401 twice around the glass surface area that is to have urethane applied.
6. Apply Essex U-402 to the same area that was prepped in the previous step. Allow 5 minutes to dry.
7. Cut the urethane adhesive applicator tip to specification.
8. Use caution when applying urethane adhesive. Apply to the outside edges of the locating tabs on the glass surface. Apply a bead of Essex 400-HV. Start at the bottom and work around to the sides of the rear quarter window glass.
9. Install the rear quarter window glass, aligning it to the marks previously made.
10. Install the wiring harness brackets.
11. Install the rear quarter trim panel.
