Removal Procedure
Important:
• The adhesion promoter must be used to assure adequate bonding of the coupling. • The adhesion promoter must be used to obtain maximum adhesion between
the new mobile antenna couplings and the glass surface. The couplings and the glass
must be kept dry and above 15°C (60°F) during the installation. Allow 6-8
hours at 15°C (60°F), for the adhesive to cure after installation. Otherwise
the new coupling may come off. • Do not use 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.
- Install the inner coupling (2) first if both the inner and the outer coupling (5) are being replaced. Refer to Mobile Telephone Antenna Inner Coupling Replacement .
- Use a small wide-bladed plastic tool to cut the double back tape material (1) while lifting up on the outer antenna coupling (5).
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 coupling. Follow the Glass Adhesion Promoter instructions on the product label.
- Remove the protective film from the adhesive backing (1,3) on the outer antenna coupling (5).
- Align the outer antenna coupling (5) to the inner antenna coupling (2).
- Press firmly on all 4 corners and 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 (2,5) and the back glass (4).
Important:
• The adhesion promoter must be used to assure bonding of the coupling. • Mask off or protect areas before applying the adhesion promoter.
Important:
• Align the inner and outer antenna couplings. • Do not touch the adhesive backing on the antenna coupling.
