Mercury 5C3Z-18813-AA Aerial Kit

To perform a resistance check, ensure the antenna cable is installed on the vehicle and unplugged from the radio, then use an ohmmeter to check the antenna between the cable and tip, expecting a reading of less than 5 ohms; if the reading is higher, replace the antenna and cable assembly. For replacement, first disconnect the cable from the negative battery terminal. For a power antenna, lower the antenna, remove the rear screws from the right side front splash shield for access, and take out the lower antenna bolt. Next, remove the nut at the top of the antenna stanchion and lower the antenna through the fender opening, using needle nose pliers to unscrew the antenna stanchion nut. Installation follows the reverse order of removal. For a manual antenna, detach the antenna lead retaining clips in the engine compartment, remove the screws, and detach the right cowl side trim panel. Then, remove the radio and unplug the antenna lead cable, take off the radio antenna base cap, remove the mounting screws, and pull the base and cable assembly through the fender opening into the engine compartment, with installation again being the reverse of removal.

Open the glove box and lower it to its fully open position.

Installation is the reverse of removal with the following additions. Install a new gasket. Untie the string or wire and attach it to the new antenna cable. Slowly pull the string and antenna cable back through the body opening and into place. Remove the string or wire.
