Removal Procedure
- Disconnect the coaxial cable (1) from the inner coupling (2) of the mobile communication antenna.
- Use a small wide-bladed plastic tool to cut the double-back tape material while lifting up on the inner antenna coupling (2).
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 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 coupling may come not
adhere. • 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 inside of 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 inner antenna coupling (2).
- Align the inner antenna coupling (2) to the existing exterior coupling.
- Connect the coaxial cable to the inner coupling (1).
- Press firmly on all 4 corners and on the center of the antenna inner coupling (2) in order to ensure proper adhesion to the rear window (4). Hold pressure on the inner coupling (2) 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:
• The RF connections for the inner antenna coupling should run parallel
to the defogger gridline. • Align the inner and the outer antenna couplings. • Do not touch the adhesive backing on the antenna coupling.
