2003 Lincoln Navigator Problems

Corrosion on Battery Cable Ends

Check the battery cable ends frequently for corrosion. Corrosion can easily migrate under the cable insulation and cause numerous electrical faults and drivability issues.

Inspect transmission/fluid every 30,000 miles

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 15,000 to 30,000 miles. If the fluid is dark or burned then the transmission fluid should be changed.

Oil coated air filer causing mass air flow sensor failure

Do not use air filters with oil-coated elements. They may cause premature failure of the mass air flow sensor; this is not covered under the warranty.
