What is one common cause of engine overheating?

One common cause of engine overheating is low coolant levels or a malfunctioning thermostat. The engine's cooling system relies on coolant to absorb and dissipate heat generated during operation. If the coolant level is low, there is not enough fluid to circulate and effectively manage the engine's temperature, leading to overheating. Additionally, a malfunctioning thermostat can hinder the proper flow of coolant by remaining closed when it should be open, thereby preventing coolant from circulating through the engine. This disruption in the cooling process can result in dangerously high engine temperatures, potentially causing damage.

High fuel levels, while an issue related to engine performance, do not directly contribute to overheating. Old engine oil may affect engine efficiency and wear but isn't a primary factor in overheating. Excessive tire pressure is important for tire safety and handling, but it does not impact the engine's temperature regulation.
