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.

 

Service power steering fluid regularly

Even though the manufacturer does not call for regular servicing, our technicians recommend servicing the power steering fluid regularly.

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.

Dealers will inspect the wheels and replace those without proper heat treating. The Ford recall number is 03S01.
