2003 Lincoln LS Problems

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.

An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

I recieved a 03 ls from a customer to do an easy tune-up. but after looking into it found most all easy items changed by previous owner and it still will not drive down road. This is the 3rd ls I have seen like this with a MAJOR problem and hope people stay away from them.
