Can Radiator Coolant Be Mixed with Water?
2 Answers
Radiator coolant should not be mixed with water, as adding water can reduce its effectiveness, lower the boiling point, diminish cooling performance, and raise the freezing point, making it prone to freezing in cold climates. Radiator coolant, also known as antifreeze coolant or antifreeze, has the following usage precautions: 1. Use the same brand of radiator coolant; 2. Check the expiration date before use; 3. Replace it approximately every 2 years or 40,000 kilometers. The method of using radiator coolant is: Drain the old fluid from the radiator, clean the radiator, and then add the new fluid. The functions of radiator coolant are: Ensuring the normal operation of the engine, effectively improving heat dissipation, and extending the service life of the engine and rubber components.
Actually, you can't casually mix Water Tank Treasure with water, especially not tap water, because this stuff is different from regular water in nature. Water Tank Treasure is antifreeze, containing ethylene glycol or propylene glycol in its formula, specifically designed to resist freezing, prevent boiling, and protect against corrosion in hoses and the engine. If you mix it with tap water, the minerals can form scale, clogging the cooling system's pipes. Over time, the cooling efficiency drops significantly, making the car prone to overheating in summer and risking a cracked radiator in winter. I once saw a car owner at a repair shop who had been mixing water long-term, resulting in a completely rusted and leaking radiator, costing over 800 yuan to fix. In emergencies, like running low on coolant on the road, you can add a small amount of distilled water as a temporary fix, but don't exceed 20% of the total volume. Afterwards, make sure to thoroughly flush and replace it with new antifreeze. Remember to use a 50% concentration mix ratio, and use a specialized tool to measure the freezing point—ensuring it doesn't freeze at -25 degrees Celsius is the most reliable.
