How to Replace the Ignition Coil in a Lincoln Navigator

The Lincoln Navigator is a luxury sport utility vehicle introduced for the 1998 model year. This model has a distributorless ignition system which uses an ignition coil instead of the distributor. The procedure for replacing the ignition coil is generally the same for all versions of the Lincoln Navigator.

• Socket wrench


• Labels


• Marker


• Torque wrench

1. Disconnect the cable from the negative terminal of the battery with a socket wrench. This will prevent you from receiving an electrical shock when you replace the ignition coils.


2. Remove the mounting bolts on the cover for the ignition coils with a socket wrench and detach the cover from the engine.


3. Label the electrical wiring to the ignition coils so that you will be able to properly attach the wiring to the new ignition coils. Detach the electrical connectors from the ignition coils.


4. Remove the ignition coils from the engine. 


5. Install the new ignition coils onto the engine. Attach the electrical connectors to the correct ignition coils by using the labels you made earlier. Remove the labels from the ignition coils.


6. Mount the cover for the ignition coils over the coils so that the screw holes on the cover align with the holes on the mounting surface. Fasten the ignition coil cover into place with the ignition coil cover bolts. Tighten the bolts to 9 ft. lbs. with a torque wrench.


7. Connect the cable to the negative battery terminal with a socket wrench. Starts the vehicle to ensure the new ignition coils are functioning properly.
