Rear Window Glass Installation

WARNING: This page is about a different car, the 2005 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Proper installation of the windshield may be difficult if sealant is cracked or the glass is pushed out by air pressure when a door is opened/closed with all the window glass closed. Leave all the windows open until the rear window glass is installed completely.

Cut away the old sealant using a razor so that a 1-2 mm {0.04-0.07 in} thickness of sealant remains along the perimeter of the frame.
WARNING:
- Using a razor with bare hands can cause injury. Always wear gloves when using a razor.
If the sealant has come off completely in any one place, apply some primer after degreasing, and allow it to dry for approx. 30 min. Then apply a 2 mm {0.08 in} thickness of sealant.
Clean and degrease the perimeter approx. 50 mm {2.0 in} from the glass end and the bonding area on the body.
If installing a reused rear window glass, perform the following procedure:
1. Clean and degrease the rear window molding installation area of the rear window glass.
2. Apply the glass primer to the rear window molding installation area of the rear window glass.
3. Remove the remaining double-sided adhesive tape from the rear window molding, and install the rear window molding (upper) to the rear window glass while aligning the molding with the center of the marking on the glass.
  NOTE:
  - Double-sided adhesive tape has been affixed to the new rear window molding.
4. Install the rear window molding (lower).

Use only glass primer on the rear window glass, and body primer on the rear window molding as shown in the figure. Allow it to dry for approx. 30 min.
CAUTION:
- Keep the area free of dirt, water and grease, and do not touch the surface. Otherwise, the primer may not properly bond to the surface of the glass and body, causing leaks to occur.

Insert the pin into the body (1), and lower the rear part (2).
NOTE:
- If the rear window glass is tilted while inserting the pin into the body, the sealant will rub against the body flange, causing damage to the sealant. Do not tilt the rear window glass to the left or right while working.

Press the pins and engage the tabs to the body.
Press the rear window glass at (a) shown in the figure from the rear of the vehicle so that the measurement of the rear window molding lip gap is within specification.

- If there are any bubbles or air leakage, repair the damaged part of the sealant and verify it again.
