Back Window Glass: Service and Repair
Back Window Removal And InstallationRemoval
1. Clean both inside and outside of glass and around it.
2. Remove lower molding and roof molding.
3. Remove upper molding by cutting with knife.
4. Using tape, cover body surface around back window glass to prevent any damage.
5. Remove high mounted stop lamp, then remove rear seat belt anchor bolt, rear pillar inner trim and partition trim.
6. Drill hole with eyeleteer through adhesive and let piano string through it.
7. Cut adhesive all around glass with piano string referring to Windshield Removal and Installation.
NOTE: Use piano string as close to glass as possible so as to prevent damage to body.
8. Using knife, smooth adhesive (1) remaining on body side so that it is 1 - 2 mm thick all around.
NOTE: Before using knife, clean it with alcohol or the like to remove oil from it.
9. When re-using glass, remove adhesive from glass leaving 2 - 3 mm (0.08 - 0.12 in.) in thickness. Use care not to damage primer coated surface.
Installation
1. Using cleaning solvent, clean window edge where window glass is to be adhered. (Let it dry for more than 10 minutes.)
2. Peel paper from one side of new glass spacers (1) and attach that lower side to windshield glass.
3. Install new back window upper molding to glass. (Don't peel off paper of molding at this stage). Warming moldings for over half an hour at 35 degrees C (95 degrees F) temperature will facilitate work.
4. To determine installing position of glass to body, position glass against body so that clearance between upper end to glass and body is specified value and clearances between each side end (right and left) of glass and body are even. Then mark match marks (1) on glass and body as shown in the figure.
Clearance between upper end to glass and body
"a": About 6.6 mm (0.26 in.)
5. Using new brush (1), apply sufficient amount of primer (2) for body along body (3) surface where window is to be adhered.
NOTE: Be sure to refer to maker's instruction for proper handling and drying time.
6. Clean glass surface to be adhered to window with clean cloth. If cleaning solvent is used, let it dry for more than 10 minutes.
7. Clean molding surface "A" with clean cloth.
8. Using new brush (1), apply sufficient amount of primer (2) for glass along glass (4) surface to be adhered to window.
NOTE:
- Be sure to refer to maker's instruction for proper handling and drying time.
- Do not touch primer coated surface.
Amount of primer specifications
Clearance "b": about 13 mm (0.50 in.)
Clearance "c": about 16 mm (0.60 in.)
9. Using new brush, apply sufficient amount of primer for molding (3) (Urethane) to surface "A" as shown in the figure.
NOTE:
- Be sure to refer to maker's instruction for proper handling and drying time.
- Do not touch primer coated surface.
10. Apply adhesive (1) as shown in the figure.
NOTE:
- Start from bottom side of glass (2).
- Height of applied adhesive should exceed that of molding (3).
- Adhesive should be applied evenly especially in height.
- Be careful not to damage primer.
- Press glass against body quickly after adhesive is applied.
- Use of rubber sucker grips is helpful to hold and carry glass after adhesive is applied.
Adhesive amount specifications (back window)
Height "d": Approx. 14 mm (0.55 in.)
Width "e": Approx. 7 mm (0.28 in.)
Dimension "f": Approx. 2 mm (0.08 in.)
11. Peel paper from moldings.
12. Holding rubber sucker grips (1), place glass onto body by aligning mating match marks in Step 4) and press it.
13. Remove match marks.
14. Install new back window lower moldings.
15. Check for water leakage by pouring water over window through a hose. If leakage is found, dry window and fill leaky point with adhesive. If water still leaks even after that, remove glass and start installation procedure all over again.
NOTE:
- Do not use high pressure water.
- Do not blow compressed air directly at adhesive applied part when drying.
- Do not use an infrared lamp or the like for drying.
CAUTION: Upon completion of installation, note the following.
- Sudden closing of door before adhesive is completely set may cause glass to become loose or to come off. Therefore, if door is opened or closed before adhesive is completely set, make sure to open all door glasses and use proper care.
- If molding is not securely in place, hold it down with a tape until adhesive is completely set.
- Each adhesive has its own setting time. Be sure to refer to maker's instruction, check setting time of adhesive to be used and observe precautions to be taken before adhesive is set.
- Refrain from driving till adhesive is completely set so as to ensure proper and sufficient adhesion.
