Removal Procedure
Important:
• Use adhesion promoter to ensure 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 installation. Allow 6 to 8 hours, at 15°C (60°F), for the
adhesive to cure after installation. Otherwise, the new couplings may not adhere. • Do not attempt to reinstall the original cellular antenna exterior coupling
or inner coupling using any type of glue, adhesive tapes, etc. 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.
- Disconnect the coaxial cable from the mobile communication antenna inner coupling.
- Use a small wide-bladed plastic tool to cut the double back tape material while lifting up on the inner antenna coupling (2).
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 back glass 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 back glass in the area where you will install the antenna coupling.
- Remove the protective film from the adhesive backing on the inner antenna coupling.
- Align the inner antenna coupling to the locating marks on the back glass or the 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 back glass (4).
- Ensure there are not any gaps between the couplings (5, 2) and the back glass (4).
- Connect the coaxial cable to the inner coupling.
- Keep the vehicle dry. Allow 6-8 hours, at 15°C (60°F), for the adhesive to cure after installation.
Follow the Glass Adhesion Promoter instructions on the product label.
Important:
• The RF connections for the inner antenna coupling should run parallel
to the defogger gridline. • Align the inner and outer antenna couplings. • Do not touch the adhesive backing on the antenna coupling.
Hold pressure on the inner coupling (2) for 10-30 seconds.
