How Much Coolant to Add?

Generally, 5 to 6 liters of coolant is sufficient for a car. The method for checking antifreeze and precautions for adding antifreeze are as follows: Method for checking antifreeze: The method for checking antifreeze is to observe whether there is a shortage of antifreeze, which means checking the scale. If the antifreeze level is below the minimum mark, it indicates a lack of antifreeze. Precautions for adding antifreeze: Do not mix antifreeze with tap water, as water has a lower freezing point and contains impurities that can easily form scale, leading to blockages and affecting the efficiency of the cooling system. For vehicles that run for long periods, high-quality antifreeze should generally be replaced once a year, while vehicles with shorter running times can have it replaced every two years or every 30,000 kilometers.
The amount of coolant to add actually depends on your radiator capacity, but generally speaking, filling it up to the MAX line is perfect. As someone who frequently tinkers with cars, I've noticed that each model is designed differently—for instance, my old SUV's radiator could hold about 6 liters, while my new sedan only takes 4 liters. Always wait for the engine to cool down before adding coolant; opening the cap while hot not only risks burns but also makes it easy to misjudge the fluid level. I typically use ethylene glycol-based coolant to ensure compatibility and prevent corrosion of engine components. Don't overfill it to avoid wasting money and polluting the environment—if the level is between MIN and MAX, it's sufficient. Regular checks can save you a lot of hassle. Why is this so important? If the engine overheats and gets damaged, repairs can be a nightmare. I've seen a friend's car break down mid-journey simply due to low coolant levels. Remember, a simple monthly check can significantly extend your car's lifespan.
When I first bought my car, I had no idea how much coolant to add. Now, I can handle it with ease. My personal habit is to fill it up to the MAX line on the reservoir—not too much, not too little, just right. My small car usually only needs a 1-liter bottle for top-up, but a complete refill requires about 5 liters. Timing is crucial—always add coolant after the engine is turned off and cooled down. Never open the cap while driving; it’s too dangerous. Last week, I overfilled it, and the excess spilled out, making a mess that was tough and wasteful to clean. I recommend keeping an eye on the temperature gauge; if it runs high, check the coolant level—it’s simple, saves trouble, and saves money. Also, opt for a reputable brand to avoid issues. Running low on coolant can cause engine overheating, and a single oversight could lead to expensive repairs.
