I am looking at a 2000 LX470 with ~106k miles. In looking at the service history there is an event at 57k miles that states:
-CUSTOMER STATES VEH OVERHEATS AND IT TAKES ONLY ABOUR 5 MINS TO GO OVER MAX HEAT ON GAUGE. T-STAT STUCK CLOSED INSTALLED NEW T-STAT COOLANT TEMP IS NORMAL. FOUND P0115 COOLANT TEMP. MALFUNCTION. CHECKED COOLANT TEMP SENSOR IT IS IN FACTORY SPEC.
And event at 86k miles that states:
- LOW FREQUENCY NOISE COMING FROM THE ENGINE AFTER STARTING UP THE VEHICLE. NOISE IS ~|~GUEST STATES A LOW FREQUENCY NOISE COMING FROM THE ENGINE AFTER STARTING UP THE VEHICLE. NOISE IS HEARD ONLY WHEN THE ENGINE IS COLD AND LASTS ONLY FOR A SHORT TIME.
My questions:
-Does anyone have any thoughts that these might be related or am I connecting dots that are not there?
-More importantly, the engine overheat incident is concerning. Is there any way to tell if the engine got hot enough to cause damage? The overheat happened ~50k miles ago. Should I be worried?
Other than the above the service history is pretty clean with the exception of some passenger side mirror complaints and two instances of misfires due to bad ignition coils.
