Windshield Glass: Installation
CAUTION:
When installing the urethane installed glass parts, the vehicle must not be driven until the urethane adhesive has cured. Adequate cure time is specified on the drive away chart for each urethane product as the temperature and humidity vary. Inadequate or incorrect curing can adversely affect the retention of the windshield glass.
NOTE:
For additional material guidelines, refer to the manufacturer's installation information.
- Dry-fit the windshield glass by centering it side-to-side and by adjusting the setting blocks (if equipped) to get the correct position of the part top-to-bottom. Make alignment marks with tape or non-staining grease pencil on both the glass and the vehicle body.
- Remove the windshield glass.
- Trim the urethane with an appropriate tool leaving a 1 mm to 2 mm base of Original Equipment urethane on the pinchweld.
- If reinstalling the original windshield glass, remove the urethane adhesive from the windshield glass.
- If installing a new windshield glass, clean the inside of the glass surface with glass cleaner to make sure the ceramic-coated area is clean.
- If installing a new windshield glass, apply urethane glass primer according to manufacturer's instructions. Allow at least 6 minutes to dry.
- Cut the applicator tip to specification.
- Apply a bead of urethane adhesive to the pinch weld. Make sure that all gaps in the urethane adhesive are smoothed into one continuous bead, starting at the bottom of the windshield glass near the center.
- Using the alignment marks, install the windshield glass.
- After the urethane has cured, check the windshield glass seal for air or water leaks through the urethane adhesive bead and add urethane adhesive as necessary.
- Install the interior rear view mirror. For additional information, refer to REAR VIEW MIRRORS .
- Install the cowl vent screen. For additional information, refer to FRONT END BODY PANELS .
NOTE:
Avoid scratching the pinch weld. For minor scratches or exposed metal on the pinch weld see manufacturer's recommendations.
NOTE:
If a new windshield glass is to be installed, attach the new molding to the edge of the glass starting at the top center then work down the sides and around the corners.
CAUTION:
Be sure to use the same brand and cure-rate products for the adhesive and primer. Do not mix different brands of urethane and primer. Refer to the Material Chart in this procedure.
NOTE:
Sika uses the same black primer for the glass and pinch weld area.
NOTE:
Use either a high-ratio, electric or battery-operated caulk gun that applies the urethane adhesive with less effort and a continuous bead.
CAUTION:
Open a window to prevent the windshield glass from being pushed out by air pressure when the door is closed.
CAUTION:
When installing urethane-installed glass parts, the vehicle must not be driven until the urethane has cured. Adequate cure time is specified on the drive away chart for each urethane product as the temperatures and humidity vary. Inadequate or incorrect curing can adversely affect the retention of the windshield glass.
