Windshield: Service and Repair
REMOVAL1. Remove windshield wiper pivot arms.
WARNING: SAFETY GLASSES AND GLOVES MUST BE WORN.
2. Remove visors and disconnect electrical connector to vanity mirror (if equipped). Drop headliner near windshield opening down to avoid cutting headliner during windshield removal. Place a small block of suitable material between headliner and roof to act as a spacer. Remove interior garnish mouldings as required.
3. Remove cowl top vent panel. Also remove the grounding screen that lies beneath the cowl vent panel.
4. Remove inside rear view mirror.
5. Use Rotunda Interior Auto Glass Cut-Out knife kit 164-R2450 or equivalent to cut adhesive. Refer to manufacturer's instructions when using tool.
CAUTION: Use care to avoid damage to instrument panel.
6. Remove windshield and moulding assemblies from vehicle using suitable suction tool.
7. Trim remaining urethane on pinch weld to within 1 and 1.5 mm (0.04 and 0.06 inch) thickness with utility knife or razor blade. When completed, surface should be smooth and free of cuts and contamination.
8. Check pinch weld sealing area for damaged sheet metal, raised metal at spot welds, rust or foreign objects which may have caused, or may cause, glass breakage. Service metal if necessary.
INSTALLATION
1. If painted sheet metal has been exposed anywhere along the pinch weld flange, use the supplied wool applicator and apply Urethane Metal Primer WSB-M2G234-C to the exposed areas.
NOTE: A minimum of 10 minutes is required for primer surface to dry.
2. Place windshield and moulding assembly on a low, stable work surface, inside up.
3. Clean windshield with an alcohol-free glass cleaner.
4. Using a clean wool applicator, wipe inside glass edge with Urethane Glass Prep WSB-M5B280-C2 25 mm (1 Inch) wide around entire periphery. Wipe off glass prep and repeat application.
NOTE: Wipe off Urethane Glass Prep WSB-M5B280-C2 immediately after application because it flash-dries. Prep application must be applied twice.
5. Properly align windshield glass to body.
a. Place windshield glass into opening. Center it top and bottom, side-to-side (adjust lower glass stops if necessary).
b. Using masking tape or crayon, make alignment marks at points on four sides of both glass and window opening.
6. Remove windshield glass and moulding assemblies from vehicle and place it back on work table.
7. Thoroughly shake and stir Urethane Glass Primer WSB-M2G314-B to make sure of uniform pigment mixing.
8. Using a clean wool applicator, apply primer to inside glass edge in same area Glass Prep was applied.
NOTE: Allow a minimum of five minutes for glass primer to dry.
9. Apply an even bead of Urethane Adhesive WSB-M2G316-B around entire sheet metal pinch weld on top of existing urethane bead. The bead should be triangular in shape, 16 mm (0.625 Inch) high and 8 mm (0.33 Inch) at base.
NOTE:
- Leave a door window slightly open until adhesive is cured.
- Apply new urethane on top of existing material on pinch weld.
10. Install windshield assembly onto vehicle, taking care to align marks on windshield glass to marks on vehicle body. Press into place to ensure good contact with urethane. Installation must be done before adhesive skins over.
11. Remove spacer and install headliner, visors, ground screen, cowl top vent panels, wiper pivot arm and interior garnish mouldings.
12. After urethane cures, install inside rear view mirror.
CAUTION: When replacing urethane installed glass parts, the vehicle should not be driven until the urethane has cured. At temperatures above 13°C (55°F) and relative humidities above 50%, adequate cure time is typically 12 to 24 hours (less at higher temperatures and humidities). See detailed instructions provided by the urethane manufacturer. Inadequate or improper curing may adversely affect the retention of the windshield.
13. Check installation for air and water leaks in urethane seal.
CAUTION: Use only urethane for service of air and water leaks in urethane set windshield.
