We have a 2002 Lincoln LS V8 that is either actually overheating or just saying it's overheating.
Last year, the temperature gauge began to spike up to the MAX suddenly. This happened soon after driving the car from a cold start, or after driving the car at highway speeds for a period of time (e.g., 1 hour).
In both scenarios, if we pulled over and shut-off the car for a few minutes (e.g., 5 mins) and restarted the car, the gauge would show the temperature in the normal range. Sometimes the temperature would remain in the normal range for the remainder of the trip. At other times, the gauge would rise above normal again.
If we didn't pull over and shut-off the car, the car would typically go into "protect mode" and automatically limit engine RPMs to avoid damaging the engine. At this point, the "check engine" warning illuminated and remained ON.
The overheating incidents started as an intermittent event, but became much more frequent - sometimes daily.
We had the following replaced in 09/2009:
- Water Pump
- Hydrolic Fan Pump Acutator
The repairs seemed to fix the problem, but gradually, the problem returned. It's odd, but We can hear the fan running when the car indicates that it is overheating.
Please advise. Please!
