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.

Mercury Spark Plug Wire delivers dependable sparks which ignite fuel swiftly and maintain rides stable. In 1939, Mercury came with cars that rode like cushions, had a sharp look and the winged-hat name that became unforgettable and made average drivers feel like posh travelers without the burn to their bank accounts. Mercury continued improving cabins with plush carpets, plush seats and additional insulation that muted wind and tire blows to allow families to talk, crank music or simply watch lines slide by as steering remained light enough to park in the city and turn around cul-de-sacs. Another production that combined confident suspensions and roomy layouts on such models as Cougar and Grand Marquis is Mercury that not only proved comfortable but also stylish, but rides up to the last showroom lights in 2011 but the legend still travels on the roads today. And it is the duty of a Spark Plug Wire wound in hard silicone, filled with carbon cores, and covered with corrosion resisting brass to send high voltage between coil and plug only when a Mercury ignition system is supposed to fire, and that is how summer after summer modern engines remain contented. Individual Spark Plug Wires are properly trimmed to the point where installation is neat and cylinders ignite in their correct sequence. Install a loose Spark Plug Wire and the misfires are gone, idle levels and throttle snaps are back immediately. Visual inspection on a regular basis detects a broken Spark Plug Wire early enough to save fuel, preserve catalysts and maintain morning starts fresh.
