Does Car Antifreeze Need to Be Replaced?
2 Answers
Car antifreeze needs to be replaced. Car antifreeze is used to add to the radiator. Since the boiling point of antifreeze is as high as 120 degrees Celsius and it can withstand low temperatures from -40 to -60 degrees Celsius, it is used to replace water as the liquid in the car radiator. The shelf life of car antifreeze is generally 2 years, so it is recommended to replace the antifreeze every 2 years or after the car has traveled more than 30,000 kilometers. If the antifreeze level is found to be below the minimum mark before reaching 30,000 kilometers or within 2 years of replacement, it is necessary to add antifreeze at a 4S shop or by yourself. Antifreeze has cooling, anti-corrosion, anti-scaling, and anti-freezing functions.
Of course, engine coolant needs to be replaced regularly because this stuff mainly protects the engine from freezing in winter and overheating in summer, while also preventing corrosion of metal components in the system. If you don't change it for a long time, it will oxidize and lose effectiveness, with increased water content or higher acidity, which may lead to corrosion clogging the radiator pipes, causing engine overheating and cylinder scoring—repairs can be expensive. Generally, it's recommended to replace it every two years or every 50,000 kilometers, depending on the vehicle's manual. I've driven long distances myself—once, I skimped on replacing it to save money, and in winter, the car wouldn't start, almost leaving me stranded on the road. Now, I've made it a habit to check the coolant level and color changes every year. Remember, a simple task can save you big trouble, ensuring your car is safe to drive.
