What does 'Please check the coolant level' mean?

Please check the coolant level indicates that the vehicle's antifreeze is insufficient and needs to be replaced or topped up immediately. The function of antifreeze and solutions when it is insufficient are as follows: Solutions for insufficient coolant: Check whether the coolant in the coolant reservoir is between the 'MAX' and 'MIN' marks, or directly check if the coolant in the radiator is sufficient. If the coolant is insufficient, it should be replenished. If the coolant is sufficient but the warning light is flashing, you can continue driving normally. Function of coolant: The function of coolant is to cool the engine. Coolant is also known as antifreeze. If the coolant is insufficient, it cannot effectively cool the engine, leading to abnormal engine operation. Coolant can effectively prevent engine failure, prevent the radiator from overheating, and provide long-term protection for water temperature, so it can be used year-round.
As a veteran driver with thirty years of experience, I deeply understand the importance of checking the coolant level. This means regularly inspecting the fluid level in the transparent reservoir under the hood to ensure it stays between the MIN and MAX markers. Coolant is the lifeline for engine cooling—too low a level can cause overheating, white smoke, or even engine seizure; too high may lead to leaks and component corrosion. I've developed a habit of checking it every week in the morning when the engine is cold, as hot coolant expands and can lead to misjudgment. Extra caution is needed during summer heat when coolant depletes faster—I always keep a bottle of OEM coolant in the car. Neglecting this could mean a roadside breakdown with repair costs high enough to buy new car parts. For safety, regular visual checks paired with professional maintenance is the ultimate money-saving strategy.
As a new driver who just got my license, I learned from my friend about the necessity of checking the coolant level. It simply means taking a quick look at the amount of liquid in the small plastic tank next to the engine, making sure it doesn't fall below the minimum line or exceed the maximum line. Coolant acts like the engine's air conditioning, preventing overheating and freezing. Insufficient coolant can cause the car to overheat, leading to minor issues like the fan running wildly or major problems like breakdowns requiring a tow. I spend half a minute checking it every Friday night—the tank is transparent and easy to inspect. In winter, the level might drop, so I need to top it up with the same type of coolant. Developing this small habit saves both peace of mind and trouble, avoiding the hefty cost of engine repairs from accidental damage. Remember to check when the engine is cold—doing it while hot is dangerous and could cause burns.
