Refer to the Safety Precautions in this section for description of tools and adhesive systems that are recommended for use in this procedure.
CAUTION: / Open the left front door glass before installing rear window to avoid pressurizing the passenger compartment. If a door is slammed before urethane bonding is cured, water leaks can result.Allow the urethane at least 24 hours to cure before returning the vehicle to use.
To avoid stressing the replacement rear window, the urethane bonding material on the rear window fence should be smooth and consistent to the shape of the replacement glass.
1. / Place replacement glass into rear window opening.
2. / Verify the glass lays evenly against the pinch weld fence at the sides, top and bottom of the replacement rear window. If not, the urethane adhesive remaining on the fence must be formed to the shape of the new glass.
3. / Using a grease pencil, mark the glass and liftgate in several locations to aid installation.
4. / Remove replacement glass from liftgate opening.
5. / Position the rear window inside up on a suitable work surface with two padded, wood 10 cm by 10 cm by 50 cm (4 in. by 4 in. by 20 in.) blocks, placed parallel 75 cm (2.5 ft.) apart .
WARNING: / DO NOT USE SOLVENT BASED GLASS CLEANER TO CLEAN REAR WINDOW BEFORE APPLYING GLASS PREP AND PRIMER. POOR ADHESION CAN RESULT.
6. / Clean inside of rear window with ammonia based glass cleaner and lint-free cloth.
7. / Apply Glass Prep adhesion promoter 25 mm (1 in.) wide around perimeter of rear window and wipe with clean/dry lint-free cloth until no streaks are visible.
8. / Apply Glass Primer 25 mm (1 in.) wide around perimeter of rear window. Allow at least three minutes drying time.
9. / Apply Pinch weld Primer 19 mm (0.75 in.) wide around the rear window fence. Allow at least three minutes drying time.
10. / If a low viscosity urethane adhesive is used, install compression spacers on the fence around the rear window opening.
11. / Apply a 10 mm (0.4 in.) bead of urethane along center line of rear window fence.
CAUTION: / Be careful so that spacers do not contaminate urethane bead.
12. / Apply 2 glass spacer clips to bottom edge of glass, approximately 150 mm (6.0 inches) inboard from each corner.
13. / With the aid of a helper, position the rear window over the rear window opening and align the reference marks.
14. / Slowly lower glass to rear window opening fence. Ensure spacers on bottom edge of glass contact sheet metal ledge. Then, push glass inward until flush to liftgate surface.
15. / Clean excess urethane from exterior with Mopar® Super Kleen, or equivalent.
16. / Apply 150 mm (6 in.) lengths of 50 mm (2 in.) masking tape spaced 250 mm (10 in.) apart to hold molding in place until urethane cures.
17. / Install rear window wiper arm.
18. / Install interior trim.
19. / After urethane has cured, remove tape strips, slide out bottom spacer clips, and then water test rear window to verify repair.
