What does coolant level low mean?

coolant level low means the antifreeze level is too low. It usually indicates an issue with the car engine. Solutions for car engine malfunctions: Read the fault codes, refer to the fault code table for each vehicle model to identify the cause of the fault, and resolve it. If the fault code is correct and the engine can start, inspect the air conditioning valve and its wiring, air ducts, air filter, etc. Functions of car antifreeze: In cold winter, it prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block. In high summer temperatures, it effectively prevents boiling and avoids overheating. Car antifreeze plays a significant role, directly affecting the car's performance and lifespan. Many people think antifreeze is only used in winter, but it should be used year-round. Antifreeze also has anti-corrosion properties. Since the engine's cooling system includes several metals such as steel, aluminum alloy, cast iron, copper, and solder used in radiator welding, the cylinder block and cylinder head are usually made of cast aluminum or cast iron, and the radiator is mainly made of copper and brass, antifreeze must protect all these metals during long-term contact. Using deionized water and appropriate additives can prevent various types of corrosion.
Last time when my dashboard showed 'coolant level low', it really gave me a scare. This thing is actually a warning for low coolant level. Our car's engine relies entirely on coolant for heat dissipation - if the level is too low, cooling becomes problematic. The easiest way to spot this is to first check that line in the overflow tank; if the liquid level is below the minimum mark, it's time to top it up. What's most concerning is if there are leaks in hoses, radiators or water pumps - this situation requires immediate attention at a repair shop. Remember to always top up with OEM coolant of the same color, as mixing different colored antifreeze can cause chemical reactions. In my case, it was just a small hose joint that had aged and was dripping - replacing the hose fixed it. Remember, when this light comes on, never stubbornly keep driving, or you'll end up with engine overheating and cylinder scoring that'll hurt your wallet to repair.
My mini cooper also showed this alert the other day, 'coolant level low' means the coolant is insufficient. It's super easy for girls to check it themselves: when the car is cold (make sure the engine is completely cooled down!), pop open the hood and look for the translucent plastic coolant reservoir, which has MIN and MAX marks on the side. If the pink liquid is below the MIN line, just go to the 4S store to buy a bottle of dedicated coolant and slowly pour it in until it reaches the middle level. My bestie had this light on last time, and it turned out to be a slow leak caused by an aging seal ring on the coolant reservoir cap. Remember, you can also take a quick glance at the coolant level during regular car washes, especially before long trips.
