What may be the result of too little coolant in the engine?

Having too little coolant in the engine can cause serious problems. The coolant helps regulate the engine's temperature by absorbing and dissipating heat. Without enough coolant, the engine cannot cool down properly, which leads to overheating. Overheating can cause the engine components to expand excessively, warp, or even seize, resulting in significant engine damage. However, a low coolant level does not directly increase fuel consumption. Understanding this helps you recognize the importance of maintaining proper coolant levels to ensure your engine runs safely and efficiently.
