Can I Change the Antifreeze Myself?

[Pierce]

You can add car antifreeze yourself. Yes, as long as the colors match, you can add it directly. Method for Adding Antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a particular focus on the five-way water pipe. The five-way pipe is named for its five connecting interfaces to various parts of the car. Antifreeze flows through the five-way pipe and is distributed to different parts of the vehicle to function. If there is any leakage of antifreeze in this section, replace the water pipe or resecure the interface as needed. Drain the old antifreeze, then flush the fluid channels with clean water. Add clean water to the antifreeze reservoir and continue pouring water into the reservoir until it flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir may have a faint pink tint. Continue adding clean water until the outflow 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, including color-distinguishing additives.
