Is it serious if the antifreeze is at the min line?

It is serious if the antifreeze is at the min line. When the antifreeze level is at the minimum mark, it needs to be replenished promptly. Otherwise, the engine may not receive adequate cooling due to insufficient antifreeze, disrupting normal circulation and causing the engine to overheat. In severe cases, this could lead to engine damage. Antifreeze typically needs to be replaced every 2 years or approximately 60,000 kilometers. The functions of antifreeze include: 1. Preventing freezing when the vehicle is not in use; 2. Cooling the engine after the vehicle is started; 3. Managing rust prevention and preventing excessive scale buildup that could block the pipes. Long-term failure to replace the antifreeze can result in degraded quality, reducing its rust prevention capabilities and potentially damaging the radiator and pipes.
I've been driving for twenty years and often encounter the situation where the antifreeze is at the min line. This isn't really a big issue, but it shouldn't be taken lightly. The min line indicates that the coolant level is slightly low, which could be due to normal evaporation or minor leaks. If not addressed promptly, the engine may overheat, potentially leading to serious internal damage. I recommend first checking the radiator and hoses for any leaks, then topping up with the same brand of antifreeze to the normal level, ensuring it doesn't exceed the max line. Always check the fluid level when the engine is cold, and never open the cap when the engine is hot to avoid burns. Additionally, during regular maintenance, have a technician thoroughly inspect the cooling system. Generally, you should top up the fluid at least once a year to prevent more serious issues. Overall, being at the min line isn't an emergency, but topping it up will give you peace of mind.
