How to Use Antifreeze?
2 Answers
The method of using antifreeze is as follows: Before adding antifreeze, it is necessary to clean the engine's cooling system. Since antifreeze generally contains descaling agents and cleaning agents, if the engine cooling system is not cleaned before use, the existing scale may come into contact with the antifreeze, leading to detachment and blockage of the water pipes. This can result in poor antifreeze circulation and cause the engine to overheat. During the use of antifreeze, regular checks are required. The validity period is generally about 2 years. When adding antifreeze, ensure it is within the validity period and also check the color and consistency of the antifreeze. If the antifreeze shows signs of deterioration, unusual odor, or becomes cloudy, it should be replaced promptly.
When I first bought my car, I was also clueless. Antifreeze mainly protects the engine from freezing in winter and overheating in summer. Using it is quite simple: First, wait for the engine to cool down, then wear gloves for safety, open the hood, and locate the coolant reservoir (usually a transparent plastic container). If the fluid level is below the Min line, top it up. Note that antifreeze must be diluted with water—for ethylene glycol types, it's about 50% antifreeze and 50% distilled water. Incorrect ratios will reduce effectiveness. If you need to replace the old fluid, first drain it: use a container to catch it, and don’t pour it randomly to avoid environmental pollution. After adding the new mixture, start the engine for a few minutes to remove air bubbles. Check the fluid level every six months to avoid sudden failures that could affect driving. It’s especially important in winter—if it freezes, the engine could be ruined. Remember to replace old fluid promptly and keep the radiator clean to extend component lifespan. With this routine maintenance, my car’s engine has never had overheating issues.
