R ENG OIL TEMP HIGH
(Caution)

The amber 'R ENG OIL TEMP HIGH' caution CAS message indicates the engine oil temperature is too high.

• The oil temperature transmitter provides a continuous indication of the oil temperature. The transmitter is a nickel wire resistance type detector mounted on the AGB oil tank below the fuel heater/oil cooler measures oil temperature. The oil temperature transducer sends data through the ECU to the EICAS. The temperature indication is shown on the engine indication system (EIS) area of the EICAS display.
• The Affected thrust lever should be reduced to prevent damage to the engine systems.
  

  NOTE: Upon reduction of engine power, the oil temperature may rise initially due to a reduction in fuel flow through the Fuel Heater Oil Cooler.
