Removal Procedure
Important:
• The adhesion promoter must be used to assure adequate bonding of the couplings. • The adhesion promoter must be used to obtain maximum adhesion between
the new cellular 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 couplings 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.
- Disconnect the coaxial cable from the mobile communication antenna inner coupling (2).
- 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 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.
- Align the inner antenna coupling (2) to the outer antenna coupling (5), or to the locating marks on the rear window above the defogger grid line.
- 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 (2,5) and the rear window (4).
- Connect the coaxial cable to the inner coupling (2).
Important:
• The adhesion promoter must be used to assure adequate bonding of the coupling. • Mark 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. • The RF connections for the inner antenna coupling should run parallel
to the defogger gridline.
