How to service and repair the Spark Plug Wire on Mercury Cougar?

Service and repair tasks for the spark plug wire start with detachments of the throttle cable and speed control cable from the engine cover. The second step requires the user to remove both the spark plug wires from the ignition coil then extract the variable camshaft timing solenoid electrical connector grommet from beneath the engine cover. After taking off the engine cover start disconnecting the spark plug wires with rotating motions while avoiding wire pulling until you unclip the wire from its retainer for connector rotation to break the spark plug seal. The spark plug wire connectors require application of silicon dielectric compound part number D7AZ-19A331-A which matches Ford specification ESE-M1C171-A before reinstalling. Removal applications should be performed in the reverse order to reinstall the products.
