If the old rear window is to be reinstalled, make alignment marks across the glass and body with a grease pencil.
Apply protective tape along the inside and outside edges of the tailgate. Using an awl, make a hole through the adhesive from inside the vehicle at the corner portion of the rear window. Push the piano wire through the hole, and wrap each end around a piece of wood.
With a helper on the outside, pull the piano wire (A) back and forth in a sawing motion. Hold the piano wire as close to the rear window (B) as possible to prevent damage to the tailgate, and carefully cut through the adhesive (C) around the entire rear window.

Carefully remove the rear window.
With a putty knife, scrape the old adhesive smooth to a thickness of about 2 mm (0.08 in.) on the bonding surface around the entire rear window opening flange:
- Do not scrape down to the painted surface of the body; damaged paint will interfere with proper bonding.
- Remove the fasteners from the tailgate.
Clean the tailgate bonding surface with a sponge dampened in isopropyl alcohol. After cleaning, keep oil, grease and water from getting on the surface.
If the old rear window is to be reinstalled, use a putty knife to scrape off all of the old adhesive, the fasteners and the rubber dams from the rear window. Clean the inside face and the edge of the rear window with isopropyl alcohol where new adhesive is to be applied. Make sure the bonding surface is kept free of water, oil and grease.
Apply glass primer to the inside of the rear window (A) where the dams and the fasteners attach. Let the upper rubber dam (B), the lower rubber dam (C) and the fasteners (D, E) as shown with adhesive tape.
- Be sure the fasteners, and upper and lower rubber dams line up with alignment marks (F).
- If necessary, cut the excess side molding along the lower edge of the rear window.
- Be careful not to touch the rear window where adhesive will be applied.
Rubber dams adhesive tape:

Thickness 0.16 mm (0.006 in.)

Width 3.5 mm (0.14 in.)

Remove the rear window.
With a sponge, apply a light coat of glass primer to the rear window (A) along the edge of the Upper rubber dam (B) and lower rubber dam (C) as shown, then lightly wipe it off with gauze or cheesecloth:
- With the printed dots (D) on the rear window as a guide, apply the glass primer to both side portions of the rear window.
- Do not apply body primer to the rear window, and do not get body and glass primer sponges mixed up.
- Let the primer dry at least 10 minutes.
- Never touch the primed surfaces with your hands. If you do, the adhesive may not bond to the rear window properly, causing a leak after the rear window is installed.
- Keep water, dust, and abrasive materials away from the primed surface.

With a sponge, carefully apply a light coat of body primer to any exposed paint around the flange where new adhesive will be applied. Let the body primer dry for at least 10 minutes:
- Do not apply body primer to any remaining original adhesive on the flange.
- Be careful not to mix up the body and glass primer sponges.
- Never touch the primed surfaces with your hands.

Put the cartridge in a caulking gun, and continuous bead of adhesive (A) on the rear window (B) around the edge of the upper rubber dam (C) and lower rubber dam (D) as shown.
Apply the adhesive within 30 minutes after applying the glass primer. Make a slightly thicker bead at each corner.

Use suction cups to hold the rear window over the opening, align it with the alignment marks you made in step 12, and set it down on the adhesive. Lightly push on the rear window until its edges are fully seated on the adhesive all the way around.
NOTE: Do not open or close any of the doors for bout an hour until the adhesive is dry.
Scrape or wipe the excess adhesive off with a putty knife or towel. To remove adhesive from a painted surface or the rear window, use a soft shop towel dampened with isopropyl alcohol.
After the adhesive has dried, spray water over the rear window and check for leaks. Mark the leaking area, let the rear window dry, then seal with sealant. Let the vehicle stand for at least 4 hours after rear window installation. If the vehicle has to be used within the first 4 hours, it must be driven slowly.
Reinstall all remaining removed parts.

NOTE: Advise the customer not to do the following things for 2 to 3 days:

Slam the doors with all the windows rolled up.
Twist the body excessively (such as when going in and out of driveways at an angle or driving over rough, uneven roads).
