Astra L4-1.8L (2009)
Tip
The metal ruler/tool should be at least the length of the window bracket. If unavailable, two rulers/tools of the length shown above (placed end to
end) could be used.
3. Insert a metal ruler (1), or equivalent tool, between the sunroof seal (2) and the window bracket (3). This will enable you to pull the seal outboard
and away from the bracket when applying the tape.
4. Cut two pieces of the squeak reduction tape (P/N 89027387) 470 mm (18.5 in) in length.
Important
To maximize the coverage against the seal, position the tape as low as possible on the window brackets.
5. With the tape's adhesive side backing still attached, pull the ruler/tool (1) outboard and position the tape (2) along the outside surface of the
window bracket. Leave enough overlap to enable wrapping the tape over each end of the bracket.
6. Starting from one end, peel the tape backing (1) and press the tape onto the window bracket. While working along the length of the bracket, ensure
that the tape stays positioned as low as possible.
