How to service and repair the ignition coil on Mercury Mountaineer?

Begin the ignition coil servicing process by disconnecting the battery ground cable and ignoring coil electrical connector before separating the radio suppressor connector. It is vital to mark the spark plug wires so the technician knows which coil terminals they belong to prior to reinstalling them. You should disconnect the six spark plug wires from the ignition coil through tapping the tabs and rotating counterclockwise to extract them upwards. The next step requires the removal of four bolts which maintain the ignition coil position. To install the new ignition coil you should tighten its bolts to 6 Nm (53 lb-in), then apply silicone dielectric compound to boot interiors before carrying out the opposite removal steps.
