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

Starting the process of ignition coil maintenance requires disconnecting both the electrical connector and radio noise suppressor electrical connector. You should maintain control of the spark plug wire boot during upward traction because thisuards both the wire and its designated ignition coil terminal. To remove the spark plug wires from the ignition coil you should simultaneously squeeze the tabs and twist before lifting upward. Use tools to eliminate the four bolted ignition coil attachments. The installation procedure requires tightening the bolts to 6 Nm (53 lb-in) while applying silicone dielectric compound inside the boots before performing the reverse removal steps for completion.
