Liftgate Window Glass: Installation
CAUTION:
After installing the new urethane installed glass, the vehicle should not be driven until the urethane adhesive has cured. 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 for the cure times as the temperatures and humidity vary.) Inadequate curing of the urethane adhesive may adversely affect the strength of the urethane adhesive bond.
- Dry-fit the new liftgate window glass by centering it side to side and by adjusting the setting blocks (if equipped) to get the correct position top to bottom. Make alignment marks with tape or non-staining grease pencil on both the glass and the vehicle body.
- Trim the remaining urethane adhesive on the pinch weld using only the full-cut method, leaving a level bead around the entire pinch weld.
- Use the wool applicator to apply Urethane Metal Primer Essex U-413 meeting Ford specification WSBM2G234- C to any exposed metal on the pinch weld. Allow six to ten minutes to dry.
- If reinstalling the original liftgate window glass, remove any excess urethane adhesive.
- If installing a new liftgate window glass, clean the inside of the glass surface with an alcohol-free cleaner to make sure the ceramic-coated area is clean.
- If installing a new liftgate window glass, apply Urethane Glass Prep Essex U-401 meeting Ford specification WSB-M5B280-C twice around the glass surface to be prepped.
- If installing a new liftgate window glass, apply Urethane Glass Primer Essex U-402 meeting Ford specification WSB-M2G314-B to the same area that was prepped in the previous step. Allow five minutes to dry.
- Install Norton Foam Sealant 565 Black Foam Tape meeting Ford specification WSB-M3G77A to the pinch weld area.
- Start at the bottom center of the pinch weld.
- Cut the urethane adhesive applicator to specification.
- Apply a bead of Urethane Adhesive Essex 400-HV meeting Ford specification WSB-M2G316-B to the pinch weld.
- Install the liftgate window glass.
- After the glass is set, check for water leaks and add urethane adhesive where needed.
- Install the high mounted stoplamp.
- Install the wiper motor. Refer to MOTOR - REAR WIPER .
- Connect the two rear window defrost electrical connectors.
CAUTION:
Care must be taken to avoid scratching the pinch weld.
CAUTION:
Wipe off the Urethane Glass Prep immediately after each application because it flash dries. Apply using deliberate strokes, making sure no to overlap the applied area.
CAUTION:
Open the windows to prevent the liftgate window glass from being pushed out by air pressure if a door is closed.
