How to Use Antifreeze Correctly?
3 Answers
Correct methods for using antifreeze: 1. Clean the engine's cooling system before adding antifreeze; 2. Regularly check the antifreeze during use. The typical validity period of antifreeze is about 2 years. Ensure the antifreeze is within its validity period when adding, and also inspect its color and texture. Replace the antifreeze promptly if you notice signs of deterioration, unusual odor, or cloudiness; 3. Generally, antifreeze should not be diluted with water, as this can cause sediment formation, severely affecting its normal function. It is advisable to use the same brand of antifreeze; 4. Do not directly add concentrated antifreeze. Direct addition not only fails to meet the freezing point requirements but can also lead to antifreeze deterioration, increased viscosity, and higher engine temperatures. Therefore, always follow the instructions for mixing when using concentrated antifreeze.
The key to using antifreeze is to regularly check its concentration, as incorrect concentration can easily lead to failure. Having driven for several years, I test the freezing point every six months, and a refractometer is quite handy for this. Maintaining a 50% antifreeze and 50% distilled water ratio is optimal—avoid using tap water to prevent engine corrosion. Always wait for the cooling system to cool down before adding antifreeze to avoid scalding from hot water. Additionally, remember to replace it every two years, as recommended in the owner's manual, since old fluid accumulates debris that reduces its protective effect. I also tried purchasing the same brand of antifreeze and draining the old fluid before refilling to prevent chemical reactions from mixing different types, which could cause leaks. Before driving in winter, always test the antifreeze to ensure its freezing point is at least 10 degrees below the local minimum temperature, preventing breakdowns on the road. If there's a leak, fix it immediately—delaying a small issue could lead to costly major repairs.
Handling antifreeze by yourself is quite simple. I wasn't very familiar with it at first, but now it's become routine. When the engine cools down, open the radiator cap—don't rush, and wear gloves to prevent splashing injuries. Testing the concentration is a must; just buy an inexpensive hydrometer, and if the reading is over 50%, the concentration is good. Be careful when adding it—pour slowly and don't fill it to the brim, leaving some room for expansion. When replacing it, don't cut corners—drain the old fluid completely, then rinse with water once to ensure the new fluid isn't contaminated. I once mixed different brands of fluid, and the system foamed up, damaging the pipes—a hard lesson, so sticking to the same brand and type is crucial. Regularly check the radiator for leaks, and patch them up promptly. Before winter, inspect it several times—safety first.
