    IMPORTANT:
    • The adhesion promoter must be used to assure adequate bonding of the coupling.
    • Mask or protect the surrounding area before applying the adhesion promoter.
  3. Apply Glass Adhesion Promoter GM P/N 12378555 (Canadian P/N 88901239) to the back glass in the area the antenna coupling is to be installed.

    Follow the Glass Adhesion Promoter instructions on the product label.

    IMPORTANT:
    • Ensure the inner and outer antenna couplings are aligned.
    • Do not touch the adhesive backing on the antenna coupling.
  4. Remove the protective film from the adhesive backing on the outer antenna coupling.
  5. Align the outer antenna coupling to the inner antenna coupling.
  6. Press firmly on all 4 corners and on the center of the antenna outer coupling (2) in order to ensure proper adhesion to the back glass (4). Hold pressure on the outer coupling (5) for 10-30 seconds.
  7. Ensure that no gaps are present between the couplings (5, 2) and the back glass (4).
