Can I Replace the Car Antifreeze Myself?
2 Answers
You can replace the car antifreeze yourself. The method for replacing antifreeze is as follows: 1. Open the car hood after the engine has cooled down; 2. Open the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old antifreeze, then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the antifreeze reservoir. Precautions for replacing antifreeze include: 1. Choose antifreeze with a low freezing point, high boiling point, and good anti-corrosion performance; 2. When replacing the antifreeze, ensure the old antifreeze is completely drained and the system is cleaned; 3. Check the hoses for any signs of aging and replace them if necessary; 4. Do not overfill or underfill the antifreeze—refer to the scale marks; 5. After adding antifreeze, wait for the fan to start running, indicating the antifreeze is working.
As someone who has repaired my car several times, I believe changing the coolant can be completely DIY. First, let the car engine cool for at least half an hour, and wear gloves to protect against burns. Open the engine hood, locate the drain valve at the bottom of the radiator, place a basin underneath to catch the old fluid, and unscrew the valve to drain it. Rinsing the inside of the radiator is even better, but avoid getting the electrical components wet. Buy the correct color and type of coolant—I prefer a 50% water and 50% coolant mixture—and slowly pour it into the radiator opening. Start the car and let it idle to warm up, then turn it off after the fan kicks in and let it cool. Top it up and vent any air bubbles from the exhaust port to prevent overheating. The old fluid should be taken to a recycling center for safe disposal. Change it every two years or 50,000 kilometers—it's cost-effective and simple. Beginners can just watch online tutorials; all you need are a basin, cloth, and bucket.
