SHOULD REVIEW PRODUCT LABELS AND TECHNI-
CAL DATA SHEETS, AND USE ONLY ADHESIVES
THAT THEIR MANUFACTURES WARRANT WILL
RESTORE A VEHICLE TO THE REQUIREMENTS OF
FMVSS 212. TECHNICIANS SHOULD ALSO INSURE
THAT PRIMERS AND CLEANERS ARE COMPATIBLE
WITH THE PARTICULAR ADHESIVE USED.
BE SURE TO REFER TO THE URETHANE MANU-
FACTURER'S DIRECTIONS

THANE ADHESIVE OR PRIMER COULD CAUSE
PERSONAL INJURY. USE THEM IN A WELL-VENTI-
LATED AREA.
SKIN CONTACT
SHOULD BE AVOIDED. PERSONAL INJURY MAY
RESULT.
ALWAYS WEAR EYE AND HAND PROTECTION
WHEN WORKING WITH GLASS.
CAUTION: Protect all painted and trimmed surfaces
from coming in contact with urethane or primers.
Be careful not to damage painted surfaces when
removing moldings or cutting urethane around
windshield.
OPERATION
The windshield is attached to the window frame
with urethane adhesive. The urethane adhesive is
applied cold and seals the surface area between the
window opening and the glass. The primer adheres
the urethane adhesive to the windshield.
It is difficult to salvage a windshield during the
removal operation. The windshield is part of the
structural support for the roof. The urethane bonding
used to secure the windshield to the fence is difficult
to cut or clean from any surface. If the moldings are
set in urethane, it would also be unlikely they could
be salvaged. Before removing the windshield, check
the availability of the windshield and moldings from
the parts supplier.
REMOVAL
The urethane adhesive holding the windshield to
the opening pinch weld (fence) can be cut using a
sharp cold knife from the exterior of the vehicle.
Using the cold knife method is effective if the wind-
shield is already broken. If the glass must be sal-
vaged, cutting the urethane adhesive from the
interior of the vehicle using a reciprocating or oscil-
lating power knife is recommended.
(1) Remove inside rear view mirror (Refer to 23 -
BODY/INTERIOR/REAR VIEW MIRROR - REMOV-
AL).
(2) Remove cowl cover (Refer to 23 - BODY/EXTE-
RIOR/COWL GRILLE AND SCREEN - REMOVAL).
(3) Remove drip rail weatherstrips as necessary to
gain access to screws holding windshield side mold-
ings (Fig. 2). Pull outward on molding at the bottom
of A-pillars using pliers.
(4) Cut urethane bonding from around windshield
using a suitable sharp cold knife. A pneumatic cut-
ting device can be used if available. (Fig. 3)
(5) Remove windshield from vehicle.
