Rear window (Hyundai Sonata EF)

Removal

1. Before you begin removing the rear window, you must first perform the following operations:

• Remove the rear seat assembly.
• Remove the rear shelf trim.
• Remove the rear pillar trim.
• Remove the lower rear window molding.
• Remove the ceiling auxiliary handles.

Note:

• To avoid hand injury, wear protective gloves.
• To avoid damage to vehicle surfaces, use protective covers.
• Do not damage the rear window heating elements or the rear window antenna.

2. Disconnect the connectors from the rear window defroster and rear window antenna.

3. Remove the rear window molding, using an auxiliary tool if necessary.



4. Lower the rear roof trim.

Caution: Be careful not to damage the rear of the roof trim.

5. The procedure for removing the rear window is similar to the procedure for removing the windshield and is given in the section "Windshield".

• Glass thickness: 3.5 mm

Installation

1. Using a knife or a special tool, carefully cut off the remains of the old glue from the body sidewall along the entire perimeter of the body opening to a thickness of no more than 2 mm.

Caution: Be careful not to remove more old glue than necessary. Be careful not to damage the painted surfaces of the car body with the knife; in case of damage, touch up with paint from the repair kit.

2. Clean the surface of the body opening edging with a sponge soaked in alcohol or a compound for removing oil and wax (degreaser).

3. Install the rear window lower molding retaining clips and rear window stoppers.



4. If the old rear window is to be reinstalled, then using a knife or a special tool, carefully cut off the remains of the old glue from the glass and from the body frame along the entire perimeter, clean the glass surface with a sponge soaked in alcohol or a compound for removing oil and wax (degreaser).


5. Center the new rear window in the body opening. Using a felt-tip pen, mark the relative position of the window and the body with lines at four points, as shown in the figure.



6. Apply a thin layer of primer to the surface around the periphery of the glass up to the rubber strip, and then let it dry for 15 minutes.

Note:

• Do not apply body primer to glass.
• Do not touch primed surfaces with your hands. Otherwise, the adhesive bond will be unreliable, which will lead to water leaks into the interior after the windshield is installed.
• Avoid contamination, water and abrasive particles on the primed surface.

7. Glue the rubber pad to the inner surface of the glass along its entire perimeter, as shown in the figure. The pad is necessary to hold the glue during the installation of the glass.




8. Install the rear window molding as shown in the figure. When installing, do not allow any gaps to form between the parts.



9. Apply a thin layer of body primer to the layer of glue remaining on the body sidewall around the entire perimeter of the body opening. The glass must be installed within 10 minutes after applying the primer.

10. Fill a special container with glue, preventing the formation of air pockets between the layers to ensure continuous application of glue. Place the container in a pressure gun (syringe) or similar device and apply a layer of glue evenly around the entire perimeter of the glass.

Note: Apply adhesive within 5 minutes after applying primer.

11. Using vacuum suction cups or a special tool, place the glass on the body opening, aligning the installation marks previously made in point "5", and lightly press the glass evenly along the entire perimeter for complete adhesion.




12. Remove excess squeezed out adhesive using a spatula or thin wire mesh.

Note: To remove adhesive from painted surfaces or rear window, use a soft towel soaked in alcohol.

13. One hour after applying the adhesive, perform a leak test on the windshield adhesive joint. When checking the leak test with cold water spray, be careful not to direct a strong stream of water at the new glass adhesive joint. The water should flow along the edges of the glass.

14. If water leaks into the interior are detected, dry the defective area, then apply additional glue.

Note:

• After installing the windshield, leave the car stationary for at least 4 hours. If for any reason it is necessary to start using the car during the first 8 hours, then it is allowed to move only at low speed.
• Ensure the glass remains dry for 1 hour after installation.

15. After completing the installation of the parts, perform the following operations:

• Install the rear seat assembly.
• Install the rear shelf trim.
• Install the rear pillar trim.
• Install the lower rear window molding.
• Install ceiling assist handles.

Note: Please follow the below recommendations for two to three days after glass installation:

• Do not slam doors when all windows are completely closed.
• Avoid significant loads on the vehicle body that occur when driving on rough terrain, roads with uneven surfaces, and driving onto/off curbs.
