11.
Check (Figure 1) and find the pre-attached butyl seal that is to be applied to the back edge of the glass. This edge of the gusset seal is thick, rather
than flat. Remove the release tape from this butyl seal only.
12.
Once installed the gusset seal should extend from one stud on the sloping side of the window module to the opposite stud on the opposite sloping
side of the window module (Figures 2 and 3). In the process, it should cover the entire top of the plastic frame behind the glass and down to just
above the row of studs across the back of the module.
13.
Starting at one side of the module, apply the butyl bead (exposed in Step 12) to the crevice between the back of the glass and the top of the
module. It is important that the butyl seals to the glass in order for the gusset seal to not leak. Additionally, try to minimize the protrusion of the
seal onto the visible side of the glass. It should be below the rounded edge of the glass.
14.
Moving across the top of the module, apply the butyl bead on the edge of the gusset seal to the back of one fixed pane, the plastic lip above the
sliding pane, and then across the back edge of the other fixed pane. Make sure that the butyl on the gusset seal seals to the two (2) small pieces of
butyl applied in Step 6.
15.
Remove the release tape from the standard seal applied in Step 9. Refer to Figure 2 to see how the gusset seal is applied to the standard butyl seal.
Starting at one side, stick the back of the gusset seal to the standard butyl seal. At this point, the gusset seal should cover the entire top of the
window module down to the row of studs.
16.
Remove the release tape from the second butyl strip on the gusset seal. This will seal to the back of the cab.
17.
Reinstall the window module according to Section 501-11 of the appropriate year F-150/F-250 LD Workshop Manual.
