REMOVAL
CAUTION: Do not pull on the spark plug wire as it may separate from the spark plug wire connector inside the spark plug wire boot.
1. Use the Spark Plug Wire Remover to grasp and twist the spark plug wire boot back and forth on the spark plug insulator to release the connector.
2. Disconnect the spark plug wire from the ignition coil by squeezing the locking tabs and twisting while pulling upward.
3. Open the spark plug wire separators and remove the spark plug wire.
INSTALLATION
CAUTION: Proper installation of the spark plug wires is critical to vehicle operation. If one spark plug wire is not properly installed on the spark plug
or ignition coil, both spark plugs connected to that segment of the ignition coil may not fire under load.
NOTE: Wipe the spark plug wires with a clean, damp cloth prior to inspection.
1. Use a small, clean tool to coat the entire interior surface of the boot with Silicone Dielectric Compound D7AZ- 19331-S (Motorcraft WA- 10), or
equivalent meeting Ford specification ESA-M1Cl71-A.
NOTE: When a spark plug wire is removed for any reason from a spark plug or ignition coil, or a new spark plug wire is installed, Silicone Brake
Caliper Grease and Dielectric Compound D7AZ-19331-A (Motorcraft WA-10), or equivalent meeting Ford specification ESA-M1C171-A must
be applied to the spark plug wire boot prior to installation.
