Installing

Preparations for Installing the Windshield

When reusing the undamaged window, cut rest of adhesive material on window and flange with V.A.G 1561 A and V.A.G 1561/8 so it is even, but do not remove completely.

Note. Residual material acts as a base for the new adhesive sealing material.

CAUTIONKeep adhesive surface free of dirt and grease. Only cut back adhesive surface shortly before installation. Do not prime or use a cleaning solution on the adhesive surface.

With New Window

Clean window all around in adhesive area using D 009 401 04.

Apply D 009 200 02 as described below.

CAUTIONCeramic application on window is not primer! It must be primed before the application of adhesive sealing material!

Applying Primer

Scheme 52

Scheme 52

Apply primer -3- with applicator -2- evenly in one stroke near the window molding -1- on the window -4-.

Beginning applying with saturated felt.

  1. Primer width approximately 20 mm.
  2. Apply primer in center of adhesive bead.
  3. Curing time 10 minutes

Window Flange

If the windshield flange was damaged, then it must be repainted and if necessary, corrosion protected.

First clean corrected area with D 009 401 04 and then apply D 009 200 02.

Windshield, Installing

Note. Cross-section thickness of adhesive bead is determined by dimension of opening in nozzle tip and rate of application.

Dimensions for adhesive application

  2. Primer
  3. Window
  1. Dimension -a- = 8 mm
  2. Dimension -b- = 12 mm
  3. Dimension -c- = note varying spacing dimensions to window edge (Scheme 56).

Position complete surface of nozzle -2- onto window.

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

Apply adhesive sealing material -1- all around on window -2- according to illustration.

Scheme 55

Scheme 55

With an undamaged removed window, apply adhesive to remaining bead.

Using double suction cups, install the windshield.

CAUTIONThe window must be installed within 15 minutes or the adhesive sealing material will not adhere properly.

Center window along sides.

  1. Distance from the edge of the windshield to the roof frame. (Scheme 56)
  2. Secure the window to the top of the roof with adhesive tape.

Before installing plenum chamber cover, first remove protective profile -2- from clamping strip.

Scheme 56

Scheme 56: Adhesive Bead Spacing to Window Edge
  1. Windshield
  2. Adhesive Sealing Material Apply adhesive at distances to window edge listed below. Dimension -a- = 2 mm Dimension -b- = 18 mm Dimension -c- = 8 mm. Dimension -d- = 18 mm
  3. Plenum Chamber Cover Retaining strip can only be pressed in after minimum window adhesive curing time.

Center window along sides.

Note varying spacing dimensions to window edge

Press drip rail -1- into clips -2- until it stops only after curing time has elapsed.

Scheme 57

Scheme 57

When pressing in drip rail, make sure sealing lip -arrow- lies flat against windshield and does not slip behind edge of windshield.

Scheme 58

Scheme 58

Affix stickers on windshield (for example, for airbag) in same position on new windshield.

Determine dimensions -a- and -b- from adhesive on old window.

Adhesive can be applied wet, with distilled water.

Apply adhesive without bubbles and slide into correct position.

Blot excess water with paper.

Note. If windshield flange was damaged during removal, paint structure should be repaired and if necessary, corrosion repair measures should be taken.

Observe minimum curing time. Refer to MINIMUM CURING TIMES .
