Quarter Window Glass: Service and Repair
Rear Quarter Glass
REMOVAL
1. REAR QUARTER GLASS ASSEMBLY
1. Disconnect the ground cable from battery.
2. Remove the rear quarter trim.
3. Remove the rear quarter glass in the same procedure as for windshield glass.
2. REAR QUARTER GLASS MOLDING
1. Remove the door inner weather strip.
2. Attach protective tapes on body. Attach two layers of protective tapes onto (A), and attach four layers of protective tapes onto (B).
3. Apply primer to the molding.
Primer:
Dow Automotive's
- BETAPRIME 5404
NOTE:
- Allow the primer to dry for eight minutes or more.
- After eight hours or more have elapsed, the molding will lose treatment effect on its surface. Thus the primer should be applied again.
4. Heat the molding while moving the dryer up and down, and facing it to the molding from the side of the vehicle (vertically against the glass surface).
CAUTION:
- Heat the molding with the dryer at a distance of 50 mm (1.97 in) from the glass.
- Do not keep heating the same position with dryer. The glass can be broken. Do not rapidly cool down the glass heated by the dryer.
NOTE: Use industrial dryers because a household hair dryer cannot generate sufficient amount of heat.
5. While heating the molding with dryer, cut the arrow position (A) upward using a scraper.
CAUTION: Do not keep heating the same position with dryer. The glass can be broken. Do not rapidly cool down the glass heated by the dryer.
6. Cut the molding rib on the arrow position (A) downward using a cutter.
CAUTION: Cutter edge shall be approximately 10 mm (0.39 in) to protect the vehicle body from damage.
7. Make a slit approximately for 15 mm (0.59 in) to the adhesive surface between molding and glass (arrow position (A)) using a cutter.
CAUTION: Use care not to cut all adhesives on the glass and body panel.
8. Make a slit approximately for 15 mm (0.59 in) to the adhesive surface between molding and body (arrow position (A)) using a cutter.
CAUTION:
- Use care not to cut all adhesives on the glass and body panel.
- Attach protective tape so that body will not be damaged.
9. Remove the molding using a long nose pliers while heating the glass surface.
CAUTION:
- Heat the molding with the dryer at a distance of 50 mm (1.97 in) from the glass.
- Do not keep heating the same position with dryer. The glass can be broken. Do not rapidly cool down the glass heated by the dryer.
10. Using a cutter, remove old adhesive for installing the molding, which occupies the greater part of the glass.
CAUTION: Be careful of receiving burns from heated glass.
INSTALLATION
1. REAR QUARTER GLASS ASSEMBLY
1. Fabricate the cartridge nozzle tip as shown and set the sealant gun with the adhesive.
2. Prepare and clean the adhesion surfaces of the glass and body using the same procedures as for the windshield glass.
3. Mount the fastener on the vehicle body.
4. Attach the outer dam rubber at a position 4 mm (0.16 in) from the glass end. Cut the excess dam rubber to the appropriate length, and use it for front side dam rubber.
5. On the front end, attach the inner periphery dam rubber at a position 13 mm (0.51 in) from the border of the glass ceramic gradation, and for other locations 17 mm (0.61 in) from the end of the glass.
6. Attach the front side dam rubber to the distance of 1.5 mm (0.06 in) from the molding edge.
7. Using the same procedures as for the windshield glass, apply primer to the glass and body.
CAUTION: Do not allow the primer to come in contact with the molding during the application of the primer.
8. Apply adhesive in the same procedure as for windshield glass.
9. Insert the glass locating pins in the side panel holes, and push the area around the locating pins to affix the glass in place.
10. Push lightly on the area around the fastener and spacer to seal.
11. After completion of all work, allow the vehicle to stand for about 24 hours.
NOTE:
- When door is opened/closed after glass is bonded, always lower the door glass first, and then open/close it carefully.
- Move the vehicle slowly.
- For minimum drying time and vehicle standing time before driving after bonding, follow instructions or instruction manual from the adhesive manufacturer.
12. After curing of adhesive, pour the water on external surface of vehicle to check that there are no water leaks.
NOTE: When a vehicle is returned to the user, tell him or her that the vehicle should not be subjected to heavy impact for at least three days.
13. Install the rear quarter trim.
2. REAR QUARTER GLASS MOLDING
1. Wipe off any dirt on the glass surface with a dry cloth.
CAUTION:
- Before wiping off the glass with wet cloth, always make sure that the glass is cold. Otherwise, it will be broken.
- Do not clean the glass with solvent.
2. Apply adhesive to the glass. Apply adhesive so that (A) will be approximately half of (B) in length.
Adhesive:
Dow Automotive's
- BETASEAL U-400HV
NOTE: Apply adhesive to inside of the glass to prevent the adhesive from being squeezed out after the molding is attached.
3. Remove the protective tape, and attach the molding.
CAUTION: When removing the protective tape, use care not to remove adhesive applied on the glass.
1. Temporarily attach the molding onto the glass from bottom to top.
2. Adjust the position so that the upper and lower clearances between molding and body will be approximately 2.2 mm (0.09 in).
3. After the positioning has been completed, press the molding into the glass to attach it securely.
4. Insert the thick paper from outside surface of the molding, and fix the molding with tape.
NOTE:
- Do not use cardboard to fix the molding because it has less shape holding strength than that of thick paper.
- This adhesive is a water absorption hardening type, which requires waterproof measures. However, plastic sheets, etc. cannot keep out water completely. Therefore, do not return the vehicle to the customer when it is raining.
5. Attach the door inner weather strip.
6. After completion of all work, allow the vehicle to stand for about 24 hours.
