What to Do If the Car's Antifreeze Exceeds the MAX Level?

[SanSara]

Adding antifreeze beyond the MAX level has minimal impact on the vehicle. Here are some additional details: 1. The excess antifreeze will expand due to heat during vehicle operation and overflow through the pressure relief valve, causing no harm other than leaving some residue. It's best to remove the excess with a syringe. 2. Antifreeze systems typically include an overflow reservoir designed to store excess fluid, marked with upper and lower level indicators. 3. It's ideal to maintain the antifreeze level between the marked indicators. Slightly exceeding the upper line is acceptable since antifreeze naturally evaporates, but keeping it at the recommended level is preferable. 4. Antifreeze should be added when the engine is cool to ensure accurate level measurement. Always use high-quality antifreeze that matches the original color or is universal. Avoid mixing different brands or colors, as their chemical compositions may vary, leading to reactions that could impair the antifreeze's effectiveness.
