What is the method for using car antifreeze?

The method for using car antifreeze is: 1. Use the same brand of antifreeze; 2. Avoid mixing with water. The steps for replacing antifreeze are: 1. Open the vehicle's engine hood, and the antifreeze reservoir can be seen in the upper right corner; 2. Open the antifreeze plug under the radiator to drain the old antifreeze; 3. Add new antifreeze, tighten the cap, and the antifreeze replacement is complete. The functions of antifreeze are: 1. To provide anti-corrosion protection for the engine's cooling system; 2. To prevent water from boiling when the engine temperature reaches 100 degrees Celsius; 3. To prevent scale formation and avoid reducing the radiator's cooling effect; 4. To ensure the engine operates normally under low temperatures.
As an experienced driver who loves being behind the wheel, I know from experience that antifreeze isn't just for winter—it also prevents engine overheating and seizure in summer. I usually check the coolant reservoir level when the engine is cold, making sure it's between the minimum and maximum marks. If it's low, I promptly top it up with fresh coolant. Remember to choose organic acid-based antifreeze for better compatibility, and don't cheap out on no-name brands—corrosion damage to radiators and pipes can lead to hefty repair bills. Pour slowly when adding coolant, using a funnel to avoid spills. A 50/50 premixed concentration is ideal—beginners shouldn't attempt diluting concentrated solutions themselves, as incorrect ratios can freeze and damage the system. I always replace it before winter, following a minimum two-year replacement cycle. When draining old coolant, let the engine cool for an hour to avoid burns from hot steam. Developing this habit can significantly extend your vehicle's lifespan.
I've been doing DIY car repairs, and changing the coolant is pretty straightforward. First, start the engine and warm it up for five minutes, then turn it off. Wait at least half an hour for it to cool completely before locating the radiator drain valve and loosening it to drain the old fluid. Next, flush the cooling system with clean water two or three times to remove any residue and ensure the pipes are clean. For the new coolant, I recommend buying pre-mixed to avoid the hassle of diluting it. Open the reservoir and slowly pour it in until the level reaches the designated line—don’t overfill. Gently shake the car body during the process to help release air bubbles. After filling, start the engine and let it circulate for a few minutes, then check for leaks and top up if needed. Remember to wear gloves to prevent skin irritation, and don’t dump the old fluid carelessly to avoid environmental pollution. Doing this regularly protects the engine from freezing cracks or overheating and reduces part wear.
When I first started driving, I didn't understand coolant, but later I learned: choose a reputable brand of coolant labeled with a 50/50 ratio on the packaging, and don't mix different types. When the engine is cold, unscrew the reservoir cap to check the level—if it's low, add new coolant instead of diluting it with water. The tank usually has min and max lines; fill it to the middle safety zone. Be extremely careful not to touch the cap when the engine is hot, as the steam can scald you. Before each winter, check the concentration using a tester to measure the antifreeze temperature point—if it's insufficient, replace it with new coolant. These simple steps prevent your car from suddenly freezing on the road and the engine from cracking.
