Removal Procedure
- Disconnect the coaxial cable from the inner coupling 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.
Important:
• Use the adhesion promoter to assure adequate bonding of the coupling. • To obtain maximum adhesion between the new mobile antenna couplings and
the glass surface, keep the couplings and the glass 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 not adhere. • Do not use any type of glue or adhesive tapes 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 instructions on the product label.
- Remove the protective film from the adhesive backing on the inner antenna coupling.
- Align the inner antenna coupling to the existing exterior coupling.
- 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).
- Connect the coaxial cable to the inner coupling (2).
- Keep the vehicle dry. Allow 6-8 hours, at 15°C (60°F), for the adhesive to cure after installation.
Important:
• You must use an adhesion promoter 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 grid line. • Align the inner and the outer antenna couplings. • Do not touch the adhesive backing on the antenna coupling.
