Ignition Cable: Service and Repair

REMOVAL
1. Grasp the spark plug boot firmly and with a twisting motion, disconnect the ignition wires from the spark plugs.

CAUTION: Do not pull on the ignition wires directly, as the wire may separate from the connector inside the boot.







2. Squeeze the back tabs to disconnect the ignition wires from the ignition coil and remove the ignition wires.







INSTALLATION
1. Connect the ignition wires to the proper ignition coil terminal.

CAUTION: Proper installation of the ignition wires is critical to engine operation. If one spark plug wire is not properly installed at either the spark plug or the ignition coil, both spark plugs connected to the ignition coil may not fire under load.

NOTE:
- Whenever an ignition wire is reinstalled or replaced with a new one, apply the Silicone Brake Caliper Grease and Dielectric Compound D7AZ19A331-A or equivalent meeting Ford specification ESE-M1C171-A to the interior surface of the ignition wire boot.
- Before installing the ignition wires, inspect the ignition wires for any visible damage; replace them if necessary.
2. Connect the ignition wires to the proper spark plugs.
