Engine Operation
4-4.5. High Oil Temperature
CAUTION: If these steps do not restore oil pressure to normal, an
engine failure or severe damage is imminent. Follow the AFM/POH
emergency instructions and LAND AS SOON AS POSSIBLE.
NOTE: Prolonged high oil temperature indications are accompanied by
reduced oil pressure. If oil pressure remains normal, a high temperature
indication may be caused by a faulty gauge or thermocouple.
If oil temperature drops as temperature increases:
1. Cowl Flaps ....................................................... OPEN (if equipped)
2. Airspeed ........................................................... Increase
3. Reduce Power if steps 1 and 2 do not lower temperature.
4. LAND AS SOON AS POSSIBLE.
5. Troubleshoot and correct the cause of low oil pressure prior to further flight.
4-4.6. Low Oil Pressure
WARNING
If oil pressure drops below 30 psi, an engine failure is
imminent. Follow AFM/POH emergency procedures.
If the oil pressure drops suddenly from a normal indication of
30-60 psi, monitor temperature closely and LAND AS SOON
AS POSSIBLE. Have the engine inspected prior to further
flight.
