2000 Lincoln Navigator Spark Plug Parts Questions & Experts Answers

• Q: How to service spark plugs on 2000 Lincoln Navigator?

  A: Service operations for spark plugs should start with disconnecting the ignition coil electrical connector. A gentle twisting motion should be used before removing the ignition coil bolt and ignition coil. Before removing spark plugs check that the engine has reached operating temperature to safeguard against thread damage and cylinder head breakdown. Keep using hand tools only because they will safeguard both the cylinder head and spark plug from damage. Clear the spark plug well from foreign material using compressed air then loosen the spark plug up to one-eighth or one-fourth of its turn. Use carburetor tune-up cleaner according to the product instructions while you fill the spark plug well until it reaches the jamb nut position. The soaking process for the cleaner needs at least 15 minutes before tightening or loosening the spark plug because this can damage it. The removing torque should be 45 Nm (33 lb-ft) so tighten and loosen the spark plug several times to achieve decreased effort before removing it. Check the spark plug condition for replacement purposes. Always replace a spark plug if its gap is outside specifications because this feature cannot be modified. Use high temperature nickel anti-seize lubricant only on the spark plug ground electrode shield while keeping away from the ground strap area. pare the new spark plug by tightening it to a torque value of 34 Nm (25 lb-ft). Check that both the ignition coil spring is correctly placed inside the boot and the boot tip remains undamaged. After positioning the ignition coil and its bolt you should apply dielectric compound inside the boots then tighten them to 6 Nm (53 lb-in). The final step of the process requires one to attach the ignition coil electrical connector.
