A display on your liquid-cooled vehicle indicates that the temperature of your coolant is excessively high. What might be the cause of this?

Your answer is correct because all three conditions can cause the coolant temperature to rise in a liquid-cooled vehicle. The radiator removes heat from the engine coolant, so if it is contaminated with dirt, its efficiency decreases. The radiator fan helps cool the radiator when the vehicle is stationary or moving slowly; if it stops working, the coolant cannot be sufficiently cooled. A perforation in the radiator system causes coolant to leak, reducing the cooling capacity and leading to overheating. Recognizing these causes helps you identify why the engine temperature might become excessively high.
