What might indicate that an oil cooler is clogged?

• A. Low oil pressure readings.
• B. High oil temperatures.
• C. Frequent engine stalling.
• D. Abnormal RPM fluctuations.

Answer: (B)

High oil temperatures can indicate that an oil cooler is clogged because the oil cooler's primary function is to dissipate heat from the engine oil. If the cooler is obstructed by debris, contamination, or any other blockage, the oil cannot circulate through the cooler effectively. This results in higher oil temperatures as the oil is not being adequately cooled as it passes through the system. Maintaining proper oil temperature is crucial for engine performance and longevity since excessively high temperatures can lead to reduced lubricating properties of the oil and potential engine damage. Monitoring oil temperature is a standard practice in aviation maintenance, and significant deviations from normal operating ranges should prompt further investigation into the oil cooler's condition.
