Can I Replace the Antifreeze Myself?

You can add car antifreeze by yourself. Just add it directly if the color is the same. Method for Adding Antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection first to check for any signs of leakage or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connections to different parts, and the antifreeze flows through it to be distributed to various parts of the car to function. If there is any leakage of antifreeze in this part, replace the hose or resecure the connection as needed. Drain the old antifreeze, then flush the fluid channels with clean water. Add clean water to the antifreeze reservoir, then continue to pour water into the reservoir to allow it to flow continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir will have a faint pink color. Continue adding clean water until the water coming out is clear. Note: Don’t forget to remove the heater hose and drain the water from the heater. Antifreeze Composition: The main components of antifreeze are: 50% pure water, 40% methanol, and 10% other substances.

I've changed the coolant several times myself and find it quite convenient, but you have to follow the steps. First, prepare the necessary tools, such as a drain pump and new coolant—it's crucial to choose the right type, don't mix up ethylene glycol-based ones. After the car has cooled down, locate the drain valve at the bottom of the radiator and slowly release the old fluid, being careful not to splash it on your skin as it's toxic. Then flush the system with distilled water or a specialized cleaning agent to circulate it. Finally, fill it up with new coolant and run the engine for a few minutes to let the air escape. The whole process takes about 40 minutes to an hour and can save you around 50 bucks. The key is to regularly check the fluid level and change it every 2 years or 30,000 kilometers to avoid long-term engine corrosion. If you accidentally spill any, it's best to ask a friend for help or just take it to a shop.

I usually do some car maintenance by myself, and changing the coolant is a relatively simple DIY. Spend some time looking up tutorials online and prepare the materials. Remember to wear gloves for protection and don't rush during the operation. The whole process saves a small hundred bucks, but don't overlook the importance of regular replacement, usually just check it every two years.

I've done it myself and found it feasible, but don't take it lightly. Just prepare a bottle of new fluid and basic tools. Operating on a cold engine is safer. Remember to clean up any residual fluid. It takes about half an hour to complete, saving both money and hassle.
