Removal Procedure

Tools Required

    • J 24402-A Glass Sealant Remover (Cold Knife)
    • J 39032 Stationary Glass Removal Tool

Window assemblies are installed from the outside of the body using a self-curing adhesive. Replacing a window assembly installed with urethane adhesive requires either partial or complete replacement of the adhesive. Partial replacement of the adhesive is known as the short method. Complete replacement of the adhesive is known as the extended method.

Window assembly removal is the same for both the short and the installation methods with one exception. Use more care with the short method while cutting out in order to ensure that an even bead of adhesive remains on the window opening in order to serve as a base for the new window assembly.

  1. Place protective coverings around the window removal area.

  3. 2.1. With the aid of an assistant, align the glass with the body sheet metal.
    2.2. Place the glass in the window frame.
    2.3. Apply a light hand pressure to the glass in order to key-out the adhesive and bond the glass to the window frame.
    2.4. Test the window for leaks with a light steady stream of warm or hot water. Do not run a heavy stream of water directly onto the freshly applied adhesive. If you find leaks, work additional adhesive material into the area.
