Using an appropriate tool, trim the urethane adhesive leaving a 1.0-1.5 mm (0.04-0.06 in) base of original equipment urethane adhesive on the
pinch weld.
2. Using a clean shop towel, brush or oil-free compressed air, clean the pinch weld area around the existing urethane adhesive. Remove any foreign
material or water that may have entered during windshield removal.
3. Install the windshield glass stops on the vehicle.
-
Rivet the stops in position.
4. If reinstalling the original windshield glass, remove the remaining urethane adhesive from the glass leaving a thin layer to bond with the new
urethane adhesive bead.
5. Install the windshield header seal on the windshield glass.
6. Clean the inside of the windshield glass with glass cleaner.
7. NOTICE: Be sure to use the same brand and cure-rate products for the urethane adhesive and glass primer. Do not mix different brands
of urethane adhesive and glass primer. Refer to the Material Chart in this procedure.
If installing a new windshield glass, apply glass primer according to manufacturer's instructions. Allow at least 6 minutes to dry.
8. Cut the urethane adhesive applicator tip to specification.
9. NOTE: The windshield glass must be positioned within 10 minutes of applying the urethane adhesive.
NOTE: Use either a high-ratio, electric or battery-operated caulk gun that will apply the urethane adhesive with less effort and continuous bead.
Apply urethane adhesive on top of the existing trimmed urethane adhesive bead on the pinch weld, starting and ending at the bottom of the
windshield near the center, making sure there are no gaps in the bead.
10. WARNING: Do not drive vehicle until the urethane adhesive seal has cured. Follow urethane adhesive manufacturer's curing directions.
Inadequate or incorrect curing of the urethane adhesive seal will adversely affect glass retention. Failure to follow these instructions may
result in serious injury to vehicle occupant(s).
NOTE: Before positioning the windshield glass, open vehicle windows to prevent the air pressure of closing doors from affecting the urethane
adhesive bond.
With the aid of an assistant, install the windshield glass.
