Undamaged Window Glass, Preparing for Installation

Special tools and workshop equipment required

  • Window Cutter -VAG1561A-
  • Window Cutter - Scraper -VAG1561/8-
  • The adhesive surfaces must be free of dirt and grease.
  • Only cut back adhesive surface just before installation.
  • Do not prime or use a cleaning solution on the adhesive surface.

- When reusing the undamaged window, cut the rest of the adhesive material on the window and flange with the -VAG1561A- and -VAG1561/8- so that it is even just before installing, but do not remove it completely.

TIP

The remaining material acts as a base for the new adhesive sealant to be applied.

New Window Glass, Preparing for Installation

- Clean all around the adhesive surface using Cleaning Solution -D 009 401 04-.

- Wipe down the cleaned surface with dry, lint free paper.

  • The adhesive surfaces must be free of dirt and grease.
  • The surface must be primed before applying adhesive sealant.
  • Glass/paint primer is electrically conductive and therefore must not touch the bus bar on the rear window defogger, for example.
  • The window glass must be inserted within 15 minutes of applying the sealant.

- Apply the Glass/Paint Primer -D 009 200 02- as described in the following.

Primer, Applying

- Using the applicator -2-, apply the glass/paint primer -3- evenly and in one stroke near the molding -1- on the window glass -4-.

A64-10140

- Begin applying with a saturated piece of felt.

  • Primer width must be approximately 20 mm.
  • The glass/paint primer must be centered to the adhesive bead.
  • Drying time: 10 minutes

Applying Adhesive

A64-0064

Dimensions for adhesive application:

1 -  Adhesive bead.

2 -  Glass/paint primer.

3 -  Window glass

  • Dimension -a- = 6.5 mm
  • Dimension -b- = 10 mm
  • Dimension -c- = note the different distances to the window edge. Refer to → Chapter "Overview - Windshield", → Chapter "Overview - Rear Side Window" and → Chapter "Overview - Rear Window".

TIP

The adhesive bead cross section is determined by the nozzle tip opening and the rate of application.

- Position the entire surface of the nozzle -2- on the window.

  • Application direction -arrow- for the adhesive bead -1-.

A64-0191

- Apply adhesive sealant -1- all around the window -2- as shown.

- Insert the windshield, partition window or rear window into the opening for the window using two suction lifters.

  • The window glass must be installed within 15 minutes or the adhesive sealant will not bond correctly.

A64-10141

Body Flange, Preparing for Installation

  • The adhesive surfaces must be free of dirt and grease.
  • Only cut back adhesive surface just before installation.

- Cut back the residue on the body flange with a cutting blade just before installing the window glass, but do not remove all of it.

TIP

The residue acts as a base for the adhesive sealant to be applied.

- If the window glass flange was damaged, repaired or replaced, the paint structure must be repaired and if necessary, the corrosion protection must be reapplied.

- First clean the repaired area with Cleaning Solution -D 009 401 04- and then apply the Glass/Paint Primer -D 009 200 02-.

Adhesive, Cleaning if Contaminated

Adhesive Remover -D 002 000 10- is recommended as a cleaning solution. Follow all safety precautions when processing.

  • When cleaning from inside the vehicle interior, do not press out on the window that was just installed.
