1. DESCRIPTION
Use this procedure to perform the replacement of glued fixed thermos window. This procedure
may also be used for the replacement of non-thermos fixed window, as the installation method is
similar.

FIXED THERMOS WINDOW PANE
When replacing a broken fixed thermos window, refer to the Parts Manual to select the
appropriate fixed window. The pre-assembled fixed thermos windows come with the upper
aluminum extrusion already glued on the windowpane. The aluminum extrusion will assure
perfect vertical positioning and support the windowpane during adhesive curing.
Four different fixed windows are available depending on the location:
Driver side:

p/n 290774 (2nd, 3rd & 5th window)

Passenger side

p/n 290774 (2nd window)
p/n 290757 (3rd window)
p/n 290758 (5th window)

4. PROCEDURE
DANGER
Park vehicle safely, apply parking brake, stop the engine. Prior to working on the vehicle, set the
ignition switch to the OFF position and trip the main circuit breakers equipped with a trip button. On
Commuter type vehicles, set the battery master switch (master cutout) to the OFF position.

INTERIOR TRIM REMOVAL
1. Inside the vehicle, remove all the finishing trims around the window. Drill the rivets where applicable.

Figure 2: finishing trims

2. Inside the vehicle, remove the extrusion at the bottom of the window.

BROKEN WINDOW REMOVAL
3. Remove all debris of broken window if applicable.
4. Remove adhesive/sealant on the involved structural members using a putty knife. Read the note
below first.
NOTE
Good adherence of glue to surface. Remove excess of glue using a putty knife. It is acceptable to
leave a thin layer of glue on the surface instead of breaking the surface of adherence with the blade. If
primed surface is slightly scratched: Accept as it is.
If glue or primer become unstuck. Remove glue locally and sand defective area

FRAME PREPARATION
5. Read GENERAL HEALTH & SAFETY / ENVIRONMENTAL INFORMATION in Appendix.
6. The vertical rubber seal found on the L.H. and R.H. side vertical members must be left in place.
NOTE
Rubber seal is stick to the structural member with pre-applied double face adhesive tape

FIGURE 7 : rubber seal

7. To avoid weak bonding, thoroughly clean the old adhesive layer on the structural member identified in
Figure 8 and Figure 9 with silicone remover (anti-silicone) p/n 682989 and clean Chix clothes. Wipe
and dry surfaces with clean blue clothes.

NOTE
For silicone remover (anti-silicone) application technique, refer to GOOD BONDING
PRACTICE – USE OF SURFACE PREPARATION PRODUCTS Section A in Appendix.

Top member: 14 mm from the edge
Bottom member: 15 mm from the edge
Right vertical member: 11 mm from the edge
Left vertical member: 11 mm from the edge

10. In preparation to adhesive application, clean the identified area on the inner side of the windowpane
i.e. plastic slat, using silicone remover (anti-silicone) 622989 (refer to Figure 13).

Figure 13 : plastic slat
