• Q: How to Properly Handle Ignition Coil Servicing on 2009 Lincoln MKZ?

  A: Service of the ignition coil-on-plug starts with disconnecting the crankcase ventilation tube-to-valve cover quick connect coupling at the left-hand side while setting it away. The upper intake manifold must be taken out first in order to work on the ignition coil-on-plugs situated on the right-hand side. The first step in servicing the ignition coil-on-plug requires the disconnection of its six electrical connectors. A gentle twisting procedure will allow the ignition coil-on-plugs to unscrew from their position. Unfasten and take out both the six bolts and six ignition coil-on-plugs. Attachment of bolts requires torque tightening to 7 Nm (62 lb-in). The coil seals need inspection for all damage indicating torn or nicked states which require immediate disposal. Each coil should get a new coil seal which needs to be fully placed inside the top chamber. The reinstallation must be done in reverse order, accompanied by dielectric grease on the inside of ignition coil-on-plug boots before connecting them to spark plugs.
