How often should the radiator water be refilled in summer?

Generally, the water in the radiator of a passenger car should be replaced every two years or every 30,000-40,000 kilometers driven. Vehicles with high usage frequency should consider replacing it earlier. Relevant information is as follows: 1. Car radiator: The service life of radiator water is 2 years, and the replacement cycle is 2 years. 2. Radiator water and antifreeze: The car radiator must be filled with special radiator water or qualified antifreeze. It is advisable to choose high-quality diluted radiator water or antifreeze. In case of unexpected water shortage, tap water can be added temporarily to prevent unnecessary losses caused by water shortage. Additionally, both special radiator water and antifreeze provide freeze and boil protection.
I have deep experience with the topic of adding water to the radiator in summer. When the weather gets hot, the engine runs faster, and the liquid in the cooling system evaporates much more quickly. I make it a habit to pop the hood every two weeks to check, ensuring the radiator fluid level is between the minimum and maximum marks. If it's low, I top it up with distilled water or a coolant mixture—never use plain water, as it can cause rust and corrode the pipes. I also check around the radiator for small leaks, like cracks in the hoses, to avoid wasting water and creating bigger problems. After every long drive, I take a quick look for extra peace of mind. After all, the engine bears a heavier load in summer, so regular maintenance helps prevent overheating issues, saving money and ensuring safety.
