Rear Window Glass 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 a 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.
Clean and degrease the ceramic parting of the glass and the bonding area on the body.

Once the primer is dry, apply sealant around the entire circumference to the edge of glass with a 11.0 mm {0.43 in} high and 5.0 mm {0.20 in} wide bead of sealant.
Align the pins and install the glass on the body.
