Windshield Installation

WARNING:

Using a razor with bare hands can cause injury. Always wear gloves when using a razor.

CAUTION:

To prevent the sealant from cracking or the glass from being pushed out by air pressure if a door is closed, open all of the windows and leave them open until the sealant has hardened.

Cut away the old sealant using a razor so that 1-2 mm {0.04-0.07 in} thickness of sealant remains around the circumference of the frame.
- If all the sealant has come off in any one place, apply some primer after degreasing, and allow it 30 minutes to dry. Then put on new sealant to create 2 mm {0.08 in} layer.
Clean and degrease an approximately 50.0 mm {1.97 in} wide strip around the circumference of the glass and the bonding area on the body.

Temporarily install the glass onto the body and adjust the glass-to-body clearance.
Make a mark on the glass directly above the V-notch of spacers.

Remove the windshield.
Paste the fasteners on the body as shown.
CAUTION:
- Keep the area free of dirt and grease, and do not touch the surface or the primer may not properly bond to the surface of the glass and body, which may cause leaks to occur.

Use a brush to apply primer to the bonding area of the glass, the body, and the molding within the region shown.
NOTE:
- Use only glass primer on the glass, and body primer on the body and the molding. Allow it to dry for approximately 30 minutes.

Once the primer is dry, apply sealant around the entire circumference to fill the gap between the dam and the edge of the glass measuring 11.0 mm {0.43 in} high and 5.0 mm {0.20 in} wide.

Align the glass marks with the V-notches in spacers and install the glass onto the body.
Press firmly inward on the glass to compress the sealant.
Verify that the gap along the upper edge is 4.9 mm {0.19 in} and side edge is 4.4 mm {0.17 in} .

Use a scraper to smooth away any sealant that oozes out. Add more sealant to any points of poor contact. Adjust the sealant as shown if necessary.
