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:
• 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 6-8 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 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 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.
- Align the inner antenna coupling to the 4 locating marks on the back glass above the defogger gridline, or 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 back glass (4).
- Ensure that no gaps occur between the couplings (5, 2) and the back glass (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:
• 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 outer antenna couplings. • Do not touch the adhesive backing on the antenna coupling.
Hold pressure on the inner coupling (2) for 10-30 seconds.
