Timely replenishment is the best solution. Regularly check the coolant level. If the coolant is below the minimum level, it indicates a shortage, and it is recommended to replenish it promptly. Below are relevant details: 1. Same brand and model: You need to purchase coolant of the same brand and model as the original. If different, the original coolant should be completely drained before adding the new one. Different brands and models of coolant may have varying formulations, and mixing them could cause chemical reactions that affect the coolant's performance. 2. Add distilled water: When the coolant level is low, you can add an appropriate amount of soft water, i.e., distilled water. Soft water has undergone deionization treatment, but the amount added should not be excessive, as it could alter the boiling and freezing points of the coolant. In fact, adding water to the radiator is not a serious issue as long as the proportion and water quality are controlled, and it is not used in extreme weather conditions. 3. Do not add hard water: Do not add tap water or other hard water. Generally, coolant has a boiling point above 106°C and a freezing point below -25°C. Adding water will lower the boiling point and raise the freezing point, making it prone to freezing in cold climates, which affects the coolant's effectiveness. Additionally, water contains impurities and ions, which can lead to scale buildup and clogging over time.
