Lincoln LS 2002 V8 - Overheating or Not Overheating?
John
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
- Thermostat
- Coolant
- 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. Thank you!
