What can lead to engine overheating?

Low coolant levels can lead to engine overheating because the coolant system is responsible for regulating the engine's temperature. Coolant circulates through the engine, absorbing heat and then dissipating it through the radiator. When coolant levels are low, there is insufficient fluid to absorb and transport heat away from the engine, which can cause the engine to reach dangerously high temperatures.

In addition, a low coolant level may compromise the effectiveness of the water pump and can lead to coolant leaks, further exacerbating the overheating issue. Maintaining proper coolant levels is essential for the cooling system's ability to function effectively and protect the engine from damage caused by overheating.
