27. Use a soft spray of warm water in order to immediately water test the window.

28. Inspect the window for leaks.

29. If any leaks are found, use a plastic paddle in order to apply extra urethane adhesive at the

leak point.

30. Retest the window for leaks.

IMPORTANT: Do not direct a hard stream of high pressure water to the

freshly applied urethane adhesive.

CAUTION: Insufficient curing of urethane adhesive may allow

unrestrained occupants to be ejected from the vehicle
resulting in personal injury.

For the moisture-curing type of urethane adhesive,
allow a minimum of 6 hours at 21°C (70°F) or greate r
and with at least 30 percent relative humidity. Allow

31. Maintain the following conditions in order to properly cure the urethane adhesive:

Partially lower a door window in order to prevent pressure buildups when closing
doors before the urethane adhesive cures.

Do not drive the vehicle until the urethane adhesive is cured. Refer to the above curing
times.

Do not use compressed air in order to dry the urethane adhesive.

32. Complete the window installation.

DESCRIPTION AND OPERATION

FULL-CUT METHOD DESCRIPTION

Use only the full cut method also know as in the field as Full Strip Method when installing
windows.

This method includes the following:

The replacement of a majority of the urethane adhesive bead remove all but approximately 2
mm (3/64 in) of the existing bead of urethane adhesive from the pinch-weld flange.

Applying pinch-weld primer to any exposed painted areas on the pinch-weld flange.

No mounds or loose pieces of urethane adhesive should remain on the pinch-weld flange. Do not
remove all traces of urethane adhesive.

at least 24 hours for the complete curing of the
urethane adhesive.

For the chemical-curing type of urethane adhesive,
allow a minimum of 1 hour.

Do NOT physically disturb the repair area until after these
minimum times have elapsed.

IMPORTANT:

If corrosion of the pinch-weld flange is present or if sheet
metal repairs or replacements are required, refinish the
pinch-weld flange in order to present a clean, primer-only
surface.

If paint repairs are required, mask the flange bonding area,

ADHESIVE SERVICE KIT DESCRIPTION

The GM Adhesive Caulking Kit P/N 12346392 contains the following items:

4 different primers

A tube of urethane adhesive with a nozzle

4 daubers

Instructions with warnings

Use the urethane adhesive caulking kit for replacement of any urethane adhesive-installed
window using the Full Cut Method.

You may use an equivalent urethane adhesive system if the system meets GM Specification
GM 3651M. Always follow the system manufacturer's instructions for application, handling
and curing.

STATIONARY WINDOW DESCRIPTION

Most stationary windows, specifically windshields, are retained to the body with urethane
adhesive which adheres the window to the body, increasing structural integrity. The reinstallation
of the windows with urethane adhesive requires complete replacement of the urethane adhesive
bead and is know as the Full Cut Method.

POWER WINDOWS DESCRIPTION AND OPERATION

prior to applying the color coat, in order to provide a clean,
primer-only surface.

Appropriate materials for these primer applications are
typically 2 component catalyzed products. Use materials
such as BASF DE15®, DuPont 2610®, Sherwin-Williams PSE
4600 and NP70® and Martin-Semour 5120,5130®, PPG
DP90LF SPIES/HECKER 3688/8590 - 3688/5150 - 4070/5090
STANDOX 11158/13320 - 14653/14980 products are approved
for this application. Follow the manufacturer's directions for
the mix, the application and the drying times.

After repairing the opening as indicated, shake the pinch-
weld primer black #3 well. Using a new dauber, apply the
primer to the primed surface of the flange in the bonding
area. Allow the primer to dry for 10 minutes.
