Cavalier L4-2.2L VIN F (2004)
Global Positioning System Antenna: Service and Repair
Coupling Replacement - Antenna Inner
COUPLING REPLACEMENT - ANTENNA INNER
REMOVAL PROCEDURE
1. Disconnect the coaxial cable from the mobile communication antenna inner coupling (2).
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.
1. Use a small wide-bladed plastic tool to cut the double back tape material while lifting up on the inner antenna coupling (2).
NOTE: 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
1. Clean the inside of the rear window with an alcohol wipe.
2. Dry the glass thoroughly using a lint free cloth.
3. 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.
IMPORTANT:
-
The adhesion promoter must be used to assure adequate bonding of the coupling.
-
Mark off or protect areas before applying the adhesion promoter.
1. Remove the protective film from the adhesive backing on the inner antenna coupling.
