2003 Lincoln LS ProblemsOverheating Due to a Damaged Impeller
Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.
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.
Very hard shifting may be noted after the transmission reaches operating temperature. Most commonly this occurs in the higher gears and reverse. Replacement of the transmission may be recommended to correct this concern.

17" chrome wheels may not have been properly heat treated. These wheels may crack at the lug nut holes, which could result in loosening of the lug nuts. The driver may experience vibration and/or abnormal noise while driving. Continued operation of the vehicle could result in the wheel failing off, increasing the risk of a crash. Dealers will inspect the wheels and replace those without proper heat treating. The Ford recall number is 03S01.
