How Often Should Antifreeze Be Replaced in a New Car?
1 Answers
New cars should have their antifreeze replaced every 1 to 2 years. This is to prevent excessive foam formation, which can reduce the heat exchange efficiency between the antifreeze and engine components. When adding antifreeze, ensure the product is within its validity period. Long-life antifreeze can last up to three years. If you notice suspended particles, sediment, or signs of deterioration or discoloration in the antifreeze, replace it immediately and clean the system. The full name of antifreeze should actually be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine block or cylinder head. Additionally, antifreeze must be used year-round.
