Impala V6-3.8L SC VIN 1 (2005)
Global Positioning System Antenna: Service and Repair
Coupling Replacement - Antenna Inner
COUPLING REPLACEMENT - ANTENNA INNER
REMOVAL PROCEDURE
1. Disconnect the coaxial cable from the inner coupling of the mobile communication antenna.
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, keep the couplings and the glass dry and greater
than 15 °C (60 °F) during installation. Allow 6-8 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 exterior or inner coupling of the original cellular antenna 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.
2. 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 back glass with an alcohol wipe.
2. Dry the glass thoroughly using a lint free cloth.
3. Apply Glass Adhesion Promoter GM P/N 12378555 or (Canadian P/N 88901239) to the back glass in the area where you will install the antenna
coupling.Follow the instructions on the product label.
