How Often Should the Antifreeze in a New Car Be Replaced?
2 Answers
Different brands may vary in quality, leading to different service lives. Generally, antifreeze should be replaced every two years, though some brands suggest 4-5 years or longer. If there is no specific guideline, you can determine whether replacement is needed based on the antifreeze's freezing point or condition. How to Check Antifreeze (Antifreeze Coolant): After the car has cooled down, open the engine compartment and check if the coolant level is sufficient. The coolant reservoir has MAX and MIN level marks. If the level is below the MIN mark when the engine is cold, add coolant until it reaches between the MAX and MIN marks. Antifreeze Replacement Interval: The recommended replacement interval for antifreeze is 100,000 kilometers, with a replacement volume of 6 liters. The color of the antifreeze does not indicate its quality; it simply reflects the different pigments added by manufacturers. After some use, the decision to replace antifreeze should not be based on its color but on its concentration (which can be tested with specialized test strips available at service stations).
I just replaced the coolant in my new car, recalling that the last change was four years ago. Actually, the replacement interval for new car coolant is quite flexible—generally recommended every 3 to 5 years, but it depends on driving habits. For example, since I drive long distances daily, I need to check it every two years because high temperatures and wear can cause the coolant to lose its anti-corrosion properties, and a faded color indicates aging. The manual states that standard ethylene glycol-based coolant lasts up to 5 years, while long-life variants can endure up to 10 years, but don’t push your luck—I once experienced a radiator clog that led to engine overheating, costing thousands to repair. A workshop friend reminded me that in northern winters, it’s crucial to regularly test the freezing point; coolant protects the system from corrosion and prevents freeze cracks. Delaying replacement for too long is like planting a time bomb for your car.
