What happens to the engine if coolant levels are too low?

When coolant levels are too low, the engine is at risk of overheating. Coolant serves to absorb and dissipate heat generated during the combustion process, maintaining optimal operating temperatures. Insufficient coolant can hinder this heat transfer, allowing temperatures to rise excessively. An overheated engine can lead to serious issues such as warped cylinder heads, cracked engine blocks, or failed gaskets, all of which may result in costly repairs. Thus, maintaining appropriate coolant levels is crucial for the longevity and proper functioning of the engine.
