Can I Add Car Antifreeze by Myself?

Car antifreeze can be added by yourself. Before adding antifreeze to the car, it is necessary to clean the engine cooling system, especially during seasonal changes when the antifreeze should be checked. If the antifreeze is insufficient, it needs to be replenished promptly. The functions of car antifreeze are: 1. To provide anti-corrosion protection for components of the cooling system; 2. To prevent scale and avoid reducing the heat dissipation effect of the radiator; 3. To ensure the engine operates within the normal temperature range. Precautions for using antifreeze include: 1. The antifreeze level should be checked regularly and replenished promptly if it is below the lower limit; 2. Observe whether the antifreeze has turbid sediments, and replace it in time if there are turbid substances; 3. Different car models have antifreeze of different colors, which cannot be mixed; 4. Before winter, measure the freezing point of the antifreeze to prevent it from freezing.
Adding coolant by yourself is completely fine. I've owned several cars and often do it myself. Coolant is mainly used to cool and prevent freezing in the engine, so regular checks are essential. Choosing the right type is key—don't mix different colors like green and pink as they can cause chemical reactions. Before adding, make sure the car is completely cooled down to avoid hot steam burns. Open the hood and locate the marked reservoir, usually transparent, and slowly pour in the same-colored coolant if the level is low, not exceeding the Max line. If you pour too much, you can use a tube to siphon some out. Doing it myself saves time and money—a bottle of coolant costs just a few dozen yuan, while a repair shop would charge at least a hundred for labor. Just be careful as coolant is toxic; avoid spilling it on your skin or the ground, and wear gloves when handling it, disposing of it in a dedicated recycling bin. Beginners shouldn't be afraid—starting with this small task can help build hands-on skills, give a sense of achievement, and prevent engine overheating damage.
As part of my car's routine maintenance, I prefer adding antifreeze myself because it's simple and practical. The steps are straightforward: After parking, wait an hour for the engine to cool completely, open the hood to locate the coolant reservoir, unscrew the cap to check the fluid level, and top it up with a same-color antifreeze mixture (typically 50% antifreeze and 50% distilled water) if it's below the Min line. Use a funnel when pouring to avoid spills, and be patient—don't pour too much at once. Antifreeze isn't just for winter freeze protection; it also prevents overheating and corrosion in summer. After topping up, start the car and drive for a few minutes to check if the temperature gauge reads normal. DIY saves time waiting in line at repair shops, especially on busy days. But remember to check the fluid level every 6 months to ensure no leaks in the system. If anything seems off, consult a professional instead of ignoring it.
