Create an engine fan fault tree analysis using EdrawMax and use its predefined templates to ensure that the fault tree analysis diagram is factually correct. Fault Tree Analysis (FTA) is a graphical tool to explore the causes of system-level failures. The attached diagram shows that the engine cooling fan is designed to move air through the radiator when the vehicle is at slower speeds or stopped. This airflow removes heat from the coolant created by the engine using the radiator as a conductor. However, sometimes some faults might happen that can be analyzed by creating an engine fan fault tree analysis diagram.
