What action can a pilot take to aid in cooling an engine that is overheating during a climb?

If a pilot encounters an overheating engine during a climb, they can reduce the aircraft's rate of climb or level off to decrease the engine's workload. Additionally, they may consider reducing power settings to lower the engine temperature. Ensuring proper airflow by adjusting the mixture or using engine cooling systems, if available, can also help mitigate overheating. Lastly, if the situation persists, the pilot should prepare for a potential descent to a safer altitude.
