Quarter Window Replacement Coupe

Removal Procedure

Caution: Always wear heavy gloves and safety glasses when handling glass to minimize the risk of injury.

Notice: Place protective covers on body to prevent paint damage.

Notice: To protect paint from damage, tape quarter panel along/under quarter glass encapsulation using a thick tape.

  1. If the quarter glass is to be reused, mark the location using masking tape or a grease pencil with relationship to roof outer drip rail and the quarter panel. During installation, marks can be aligned to guide the glass to the desired position.
  2. Remove the roof outer drip rail. Refer to Roof Front Drip Molding Replacement - Left Side and Roof Front Drip Molding Replacement - Right Side in Roof.
  3. Remove the quarter window upper garnish molding from the right side only. Refer to Garnish Molding Replacement - Quarter Window Upper in Interior Trim.
  4. Partially remove the quarter lower trim panel.

  5. Object Number: 866584  Size: SH

    Notice: Failure to use tongue depressors or equivalent could result in the piano wire damaging encapsulation.

  6. Use two 154 mm (6 in) tongue depressors, or equivalent, and place under B-pillar encapsulation.
  7. Feed piano wire around the perimeter of the quarter glass being careful not to damage the finish on the quarter panel.
  8. Tape the quarter glass to the body to retain the glass as the urethane is being cut.
  9. Caution: When using power tools that may create smoke when cutting urethane sealant, work should be done in a well ventilated area and/or with a NIOSH/MSHA Approved air supplied respirator to prevent possible harmful exposure.

    When the urethane adhesive is heated enough to give off smoke, high levels of methylene diisocyanate (MDI) may be present.

    Unprotected exposure to methylene diisocyanate (MDI) may result in severe, chronic, debilitating respiratory problems.

  10. Use a sawing motion to cut through the urethane.
  11. Remove the quarter glass and tape.
  12. Remove the old urethane with a razor knife leaving a thin film, approximately 1-2 mm (0.04-0.08 in) around the perimeter of window opening and old quarter glass, if being reused.

Installation Procedure

Notice: Loose urethane and/or rough surfaces may cause sealing problems during installation. For cars with a sunroof, it is important to install the fasteners to the new roof assembly before the roof is installed in place.


    Object Number: 867123  Size: SH
  1. Install the roof outer drip rail screws in order according to illustration.
  2. Notice: Refer to Title not found in the Preface section.

  3. Install the quarter lower trim panel.
  4. Tighten
    Tighten the lower quarter trim panel fastener to 1.5 N·m (13 lb in).

  5. Clean the entire window opening and glass bonding surfaces with a clean, lint free, alcohol dampened cloth. Allow to air dry.
  6. Notice: To prevent corrosion, paint damage around the window opening by the power glass removal tool must be covered with pinchweld primer. Do not prime over existing urethane. Follow manufacturers recommendations for drying time.

  7. Quarter glass installation:
  8. 4.1. Shake glass prep primer, Clear #1 or equivalent, well before using.
    4.2. Apply glass prep primer, Clear #1 or equivalent, around the entire perimeter of the glass using a dauber.
    4.3. Wipe dry with a clean lint-free cloth.

            Important: Primer area has a minimum width diameter of 18 mm (0.71 in) in area (A) area.

    4.4. Shake glass primer, Black #2 or equivalent, well before applying.
    4.5. With a new dauber, apply glass prep primer Black #2 or equivalent, around the entire perimeter over Clear #1 or equivalent.
    4.6. Allow primer to dry 5 minutes before applying urethane.
  9. Apply a smooth continuous bead of adhesive directly to old urethane adhesive in glass opening or to glass. Apply according to dimensions shown. Start and stop application of urethane at bottom of windshield.
  10. Bead Dimension

        • Minimum Width: Dimension (B) 8 mm (0.32 in).
        • Minimum Height: Dimension (C) 16 mm (0.64 in).
  11. Place the quarter glass into the window opening.
  12. • If reusing the old quarter glass, align to the previously marked position.
    • For new quarter glass, align the locating pins to the holes in the window opening.

    Notice: Until the new urethane has cured, air pressure from a closing door may cause the glass to move. To prevent this, lower the opposite side door window a minimum of 76 mm (3 in) before closing the door.

    Important: The vehicle must remain at normal room temperature for 6 hours to complete proper cure of the adhesive. Refer to the manufacturer's recommendation.

  13. Press glass firmly to wet-out and set adhesive. Use care to avoid excessive squeeze out which would cause an appearance problem. Using duct tape or equivalent , tape glass up to roof.
  14. Watertest the vehicle at once using soft spray. Use warm or hot water if available. Do not direct hard stream of water at fresh adhesive material. Water applied on top of urethane adhesive, during watertest or as a separate operation, will speed up the cure of the urethane.
  15. Inspect for leaks from inside the car. Paddle in extra adhesive at leak points using a tongue depressor or similar flat flexible tool.
  16. Install the quarter window upper garnish molding, right side only.
