2008 Lincoln Navigator Spark Plug Parts Questions & Experts Answers

• Q: How to service and repair spark plugs on 2008 Lincoln Navigator?

  A: You must start all service and repair work on the ignition coil-on-plug from all vehicles. Protection of both the spark plug threads and cylinder head requires engine temperature to reach warm levels after cooling down before any spark plug work starts. Avoid touching spark plugs before the engine reaches this temperature. Manual hand tools should be used when installing and removing spark plugs since they can prevent any potential damage. The spark plug well needs compressed air cleaning from foreign matter before the removal process. Original spark plugs should be put back into their original cylinder of removal while new plugs can find any cylinder position. Spark plugs should receive a torque of 12 Nm (9 lb-ft) after installation when working with late build vehicles yet early build vehicles require 34 Nm (25 lb-ft). Insect the spark plugs after removal before installing new ones according to the opposite sequence of removal.
