Which of the following could cause an engine to overheat?

The reason the selection indicating low coolant levels, a faulty thermostat, a blocked radiator, or a malfunctioning water pump is correct in identifying causes of engine overheating is due to how each of these components plays a critical role in maintaining the engine's cooling system.

Coolant levels are essential because if the coolant level is low, there is insufficient fluid to absorb and dissipate heat from the engine. The thermostat regulates the flow of coolant; if it fails, it may not open when needed, causing the engine to trap heat. A blocked radiator restricts the airflow necessary for cooling the coolant, preventing effective heat exchange. Additionally, a malfunctioning water pump can result in inadequate coolant circulation, further hindering the cooling process. Each of these elements contributes directly to the engine's ability to manage temperature effectively, making them all significant factors in overheating.

The other options do not directly relate to the engine's temperature regulation in the same way. High oil levels can lead to other issues, like foaming, but they do not typically cause overheating directly. Poor air intake quality could affect performance and combustion efficiency, yet it has a less direct impact on engine temperature compared to the cooling system components. Excessive fuel pressure might disrupt the air-fuel mixture and lead to inefficient
