1. Getting Started:
For vehicle and glass preparations please refer to AGSC/ANSI 002-2002 as well as your adhesive manufacturer’s recommendations. Inspect the windshield for defects and any contamination that may compromise the bonding of the adhesive.

First remove the 2 A- pillar covers with a plastic pry tool starting at the top and release the metal retaining clip. For the lower clip that is made of plastic, gently pry out on the cover and cut the clip with an appropriate cutting device. This is the recommended procedure by Nissan and will require new clips. Nissan also recommends removing the small roof cover under the sun visors. Remove the small cap on the sun visor to gain access to the retaining screws. Remove the screws and unplug the wiring harness connector. Next unplug the rear view mirror connector. There will be six clips holding the cover to the car. Now move to the cowl area. Remove the wiper arm caps, nuts and remove the wiper arm. To remove the cowl panel, first remove the master cylinder cover and battery cover. Next remove the hood ledge cover clips and remove the covers. Remove the cowl seal and center section. Then remove the passenger side cowl by removing clips and the prawl fingers; slide the panel toward the front of the car releasing it from the windshield area. Repeat the same steps for the driver’s side. To remove the left and right remove the two (per side) retaining nuts at the top of the A-pillar and remove the front-side glass run assembly. Next remove the glass run assembly screws and remove the weatherstrip retainer.

2. Removing the Windshield:
For the sides and top of the windshield, a cold knife or power tool can be used as well as wire. For the bottom, a power tool or wire can be used. Keep in mind that there is no one correct method of removal. The technician should use the tool with which he feels most comfortable and the one that achieves a safe removal (both for the vehicle and the technician).

3. Preparing for the New Windshield:
Trim the existing urethane bead, leaving it 1 to 2 millimeters (mm) in height. Use your adhesive manufacturer’s pinchweld primer to prime all scratches if any exist and allow for proper drying, according to your adhesive manufacturer’s recommendations. Please note that only the full-cut method is permitted by the AGSC/ANSI 002-2002 Standard.

4. Placement of the New Windshield:
Dry-fit the new windshield and mark it properly to ensure the correct setting procedure. Prepare the windshield according to your adhesive manufacturer’s recommendations and then apply the adhesive and install the windshield. Nissan uses a 12mm tall by 7mm wide tip cut at a 60 degree angle. Make sure the deck height is correct and the markings on the windshield line up with those on the body that were applied during the dry set.

5. Finishing Touches:
Install the cowl, wipers and mirror in reverse order. Be sure to check the operation of the electronic mirror if equipped and wiper operation before returning the vehicle to the owner. Be sure to record all lot numbers from the adhesive, VIN number and primers as well as the DOT number from the windshield.
