Installation
All vehicles
CAUTION: After installing the urethane installed windshield, 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 ESSEX drive away chart for cure
times as temperatures and humidity vary). Inadequate curing of the urethane adhesive may
adversely affect the strength of the urethane adhesive bond.
1. 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.
2. CAUTION: Care must be taken to avoid scratching the pinch weld.
Trim the remaining urethane on the pinch weld using only the full-cut method. in this method,
most of the existing urethane is removed leaving a level bead around the entire pinch weld.
