- Inspect the following components for the causes of a broken windshield:
• | The flange of the windshield opening |
• | The windshield reveal molding |
- Inspect for any of the following concerns in order to prevent
future breakage of the windshield:
• | Hardened spot weld sealer |
• | Any obstruction or irregularity in the pinchweld flange |
Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs
or replacements are required, the pinchweld flange must be refinished in order
to restore the bonding area strength. If paint repairs are required,
mask the flange bonding area prior to applying the
color coat in order to provide a clean primer only
surface. Materials such as BASF DE17®,
DuPont 2610®, Sherwin-Williams PSE 4600
and NP70 and Martin-Semour 5120 and 5130 products
are approved for this application.
- After repairing the opening as indicated, perform the following steps:
4.2. | Remove no more of the urethane adhesive from the pinchweld flange

proper clearance between the windshield and the pinchweld flange. |
4.3. | Remove all traces of broken glass from the outer cowl panel, seats,
floor and defroster ducts. |
4.4. | Clean around the edge of the inside surface of the window with
a 50/50 mixture of isopropyl alcohol and water by volume on a dampened
clean lint-free cloth. |
- After repairing the opening as indicated, shake the pinchweld
primer (black #3) for at least one minute.
Caution: Failure to prep the area prior to the application of primer
may cause insufficient bonding of urethane adhesive. Insufficient bonding
of urethane adhesive may allow unrestrained occupants to be ejected from
the vehicle resulting in personal injury.
