2003 Lincoln LS Problems

Overheating 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.


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.

3.9L v8, 5r55s, 4th and R shift erratically when @ temp, Fine when cold

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.

2003 Lincoln LS Recalls

17" Chrome Wheels May Loosen and Fall Off

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.

This is the best of two vehicles that I own. Only repair problem at 14,000 miles was Catalytic Converters (Factory Replaced), left and right side. Also replaced during regular maintenance: Air Filter, A/C Cabin Air, Fuel Filter, Oil & Oil Filter, Brake Pads, and PCV Valves.
