What is a common cause of an engine overheating?

A common cause of an engine overheating is low coolant levels. The engine's cooling system is designed to regulate temperature by circulating coolant through the engine and then to the radiator, where it dissipates heat. If the coolant levels are low, there isn't enough fluid to absorb heat effectively, leading to increased engine temperature. Insufficient coolant can occur due to leaks in hoses, the radiator, or other components, or it can result from poor maintenance practices. When coolant levels drop, the boiling point of the coolant decreases, making it easier for the engine to overheat, which can lead to severe damage if not addressed promptly.
