2006 Lincoln Navigator Problems

Problems With EGR System are Common in High Dust Areas

In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.

Adjusting AC Clutch Air Gap

Checking and adjusting the AC compressor clutch air gap can extend the service life of the AC compressor.

Spark Plugs May be Difficult to Remove

Our technicians tell us the spark plugs in this engine can be very difficult to remove. Ford has issued a service bulletin (08-7-6) to address this issue, which includes a recommended procedure on how to remove the plugs. Failure to follow the recommended procedure can result in the one or more spark plugs breaking off in the cylinder head.

The recommend procedure is as follows. Using this procedure will greatly reduce the chance of breaking a spark plug.

1. Break the spark plugs loose when the engine is warm.
2. Turn each plug 1/8 to 1/4 turn and soak the treads with 1/2 to 3/4 teaspoon of Motorcraft Carburetor Tune-Up Cleaner or a quality penetrating oil. Do not try to remove the plugs at this time.
3. Let the threads soak for at least 15 minutes.
4. After the soak period, tighten and loosen each spark plug, working it back and forth until the turning effort is reduced. Then, you can remove the spark plug.

There are special tools available to remove the broken spark plugs and repair shops will often charge additional labor time, over and above the quoted spark plug replacement cost, for the removal of each broken spark plug.

Ford recalls 2006 E150, E250, E350 Escape, Expedition, F150, Ranger, Taurus, Lincoln Navigator, Mercury Mariner, and Mercury Mountaineer due to a possible lack of lubricant on the wiper motor output shaft gear.

Transmission Park Lock May Not Engage

289 vehicles may have been built with an incorrectly manufactured automatic transmission parking pawl guide plate. This could cause the transmission park lock system not to engage as expected. If the vehicle was parked on an incline and the parking brake was not engaged, a roll-away condition could occur, increasing the risk of a crash. Dealers will repair and replace the automatic transmission guide plate. The Ford recall number is 05S39.
