An empty coolant reservoir can result from a leak in the radiator, hoses, or the reservoir itself. Evaporation due to a loose or faulty cap is another possibility. Overheating may cause coolant loss, especially if the engine temperature sensor is faulty. Perform a visual inspection for leaks, and check the coolant cap for secure fit. Consider conducting a pressure test to identify hidden leaks. Always use the correct coolant type when refilling and seek professional help if the issue persists to avoid engine damage.
