1. GETTING STARTED:
First, when choosing an adhesive for this job, you must note that General Motors (GM) requires the adhesive to meet its specification, 3651G. Always follow the Auto Glass Replacement Safety Standard (AGRSS®) for proper installation.

Inspect the windshield for defects and any contamination that may compromise the bonding of the adhesive. Also look for any distortion, scratches or defects on the glass or moulding. I recommend you test the rain sensor before starting the installation.

If the vehicle is equipped with an electrochromic mirror or rain sensor, make sure the ignition is off. First, remove the rearview mirror by removing the electrical connector cover and unplugging the connector. Next, adjust the mirror to the full upward position and loosen (but do not remove) the set screw and slide the mirror upward. Next, remove the wiper caps and wiper nuts. The use of a wiper puller may be required to remove the wiper arms properly. Mark the wipers to ensure proper installation for both the left and right sides.

Then, remove the air inlet grille (cowl panel) by removing the rear cowl weatherstrip. Then release the passenger side retainer at the windshield far enough to remove only the passenger side. There are three small, rivet-type retainers used on the passenger side that can be removed easily with a small, flat tool; after that, remove the passenger-side cowl panel. For the driver-side panel, there are six rivet-type retainers to be removed, along with the hose for the washer nozzle.

2. REMOVING THE WINDSHIELD:
GM recommends using only water as a lubricant for power tools and the use of a cold knife for removal. 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.

3. PREPARING FOR THE NEW WINDSHIELD:
Trim the existing urethane bead, leaving it 1 to 2 millimeters in height. Use your adhesive manufacturer’s pinchweld primer to prime all scratches, if any exist, and allow to dry according to your adhesive manufacturer’s recommendations. Please note that only the full-cut method is permitted by the AGRSS/ANSI 002-2002 Standard.

4. PREPARING FOR THE NEW WINDSHIELD:
Dry-fit the new windshield and mark it properly to ensure the correct setting procedure. Wet-scrub the frit and prepare the windshield according to your adhesive manufacturer’s recommendations, and then apply the adhesive and install the windshield. Make sure the deck height is correct (factory bead size is approximately 8 by 12 mm) and that 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 (mirror set screw is 18 lb. in. or 2 Newton meters (Nm)) in reverse order from removal and torque the wiper nuts to 21 lb. ft. or 29 Nm. The factory location for the wiper blade placement can be determined by aligning the wiper blade tip to the small circles located in the black frit band area of the lower windshield. Be sure to check the rain sensor and wiper operation before returning the vehicle to the owner.
