Global Positioning System Antenna: Service and Repair
Coupling Replacement - Antenna Outer
COUPLING REPLACEMENT - ANTENNA OUTER
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.
1. Install the inner coupling first if both the inner and the outer coupling are to be replaced.
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.
2. Use a small wide-bladed plastic tool to cut the double back tape material while lifting up on the outer antenna coupling (5).
INSTALLATION PROCEDURE
1. Clean 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 (Canadian P/N 88901239) to the back glass in the area where you will install the antenna
coupling.
Follow the Glass Adhesion Promoter instructions on the product label.
