2003 Lincoln LS ProblemsOverheating Due to Damaged Water Pump
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.
Checking and adjusting the AC compressor clutch air gap can extend the service life of the AC compressor.
