Can I Buy and Add Antifreeze by Myself?

You can add antifreeze to your car by yourself. Before adding antifreeze, it is necessary to clean the engine cooling system, especially during seasonal transitions. It is important to check the antifreeze level and add it promptly if it is insufficient. How to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze, although it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), you should not continue driving and need to add antifreeze immediately. Check the water level marks on the antifreeze bottle. The antifreeze level should normally be between the maximum and minimum marks. If the antifreeze is below the minimum mark, it indicates a deficiency. Antifreeze replacement cycle: For vehicles that run for long hours, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter running times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-life antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the antifreeze, the system should be cleaned and the antifreeze replaced promptly.
I think it's completely fine to buy and add antifreeze by myself. As someone who frequently works on my own car, I do this every year and find it quite convenient. First, you need to check the coolant reservoir level. With the engine cold, open the hood and locate the white plastic tank with min and max lines. If it's low, go to an auto parts store and buy a bottle of antifreeze that matches your car model and color - for example, my car uses universal green type which is quite affordable. When refilling, pour carefully to avoid spills as it can corrode paint or contaminate the ground. After my last refill, I noticed the system became more stable with even engine operating temperatures, plus I saved dozens in repair fees. Remember never to mix different colored antifreeze - like green and orange together might cause chemical reactions that clog pipes, a lesson I learned from experience. This regular maintenance trick not only protects the car but also gives me deeper mechanical understanding.
