Removal Procedure
- Install the inner coupling first if both the inner and the outer couplings are to be replaced. Refer to Mobile Telephone Antenna Inner Coupling Replacement .
- Use a small wide-bladed plastic tool to cut the double back tape material while lifting up on the outer antenna coupling.
Important:
• The adhesion promoter must be used to assure adequate bonding of the coupling. • To obtain maximum adhesion between the new mobile antenna couplings and
the glass surface, the adhesion promoter must be used and the couplings and the glass
must be kept dry and above 15°C (60°F) during the installation. Allow 6 to
8 hours, at 15°C (60°F), for the adhesive to cure after installation.
Otherwise the new couplings may come off. • Do not use using any type of glue, adhesive tapes, etc. to reinstall the
original couplings. Doing so may eliminate the cellular signal transfer through the
glass and reduce the maximum performance of the system, including the air bag deployment
notification.
Notice: If you use a razor blade or other sharp tool in order to remove the adhesives or foreign objects from the inside of the rear window, use the blade carefully. Damage to the grid lines may result.
Installation Procedure
- Clean the rear window with an alcohol wipe.
- Dry the glass thoroughly using a lint free cloth.
- Apply Glass Adhesion Promoter GM P/N 12378555 (Canadian P/N 88901239) to the rear window in the area where you will install the antenna coupling. Follow the Glass Adhesion Promoter instructions on the product label.
- Remove the protective film from the adhesive backing on the outer antenna coupling.
- Align the outer antenna coupling to the inner antenna coupling.
- Press firmly on all 4 corners and on the center of the antenna outer coupling (5) in order to ensure proper adhesion to the rear window (4). Hold pressure on the outer coupling (5) for 10-30 seconds.
- Ensure that no gaps occur between the couplings (5, 2) and the rear window (4).
- Keep the vehicle dry. Allow 6 to 8 hours, at 15°C (60°F), for the adhesive to cure after installation.
Important:
• The adhesion promoter must be used to assure adequate bonding of the coupling. • Mask off or protect areas before applying the adhesion promoter.
Important:
• Align the inner and the outer antenna couplings. • Do not touch the adhesive backing on the antenna coupling.
