What is the low coolant level warning light icon?

When the coolant level is low, a thermometer icon will illuminate on the vehicle's dashboard. The functions of coolant are as follows: 1. Cooling function: Cooling is the basic function of coolant. When the engine is running, it generates a large amount of heat, with 60% of this heat being dissipated to the surrounding space through the cooling system. Water and methanol-based coolants have low boiling points and are prone to boiling. If the vehicle operates under conditions where the coolant is boiling, even for a short period, it can cause engine damage or even complete failure. 2. Anti-corrosion function: The cooling system consists of components such as the radiator, water pump, cylinder block, cylinder head, and water distribution pipes made from various metals including steel, cast iron, brass, copper, aluminum, and solder. Due to the different electrode potentials of these metals, electrochemical corrosion can easily occur in the presence of electrolytes. Additionally, acidic byproducts formed from the decomposition of glycol-based substances in the coolant, as well as acidic exhaust gases from fuel combustion that may penetrate the cooling system, can accelerate corrosion within the cooling system.

The antifreeze warning light is typically a red or yellow thermometer-shaped icon on the dashboard, sometimes with a wavy line indicating low fluid level. I’ve encountered it a few times during long-distance drives—when this light comes on, it means the coolant level is too low or there’s an issue. Never ignore it, as it can lead to engine overheating and damage. Once, when I saw it flashing, I immediately pulled over to check and found a leak in the radiator. Fortunately, timely action prevented a bigger breakdown. It’s a good habit to regularly check the coolant’s color and level, at least once a month, to ensure safety. Antifreeze isn’t just for preventing freezing; it also prevents rust and aids in heat dissipation, so always use the specialized formula and avoid substituting it with plain water.

That warning light really made me nervous when I first bought my car. It's usually a red or yellow thermometer-like icon that lights up. As a newbie, I checked the manual and found out it indicated low coolant level, which requires immediate attention. I remember the first time it came on, I pulled over, popped the hood, and topped up with proper antifreeze. Later I learned it might actually signal indirect issues like aging hoses or leaks. Regular fluid level checks during maintenance can prevent this, especially in winter. The cooling system is the engine's lifeline - low fluid causes overheating or even engine seizure, so never delay inspection for safety.

The antifreeze warning light typically appears as a thermometer icon on the dashboard, usually in a red hue, and illuminates to alert issues in the cooling system. I learned this from hands-on experience replacing parts—when it lights up, it could indicate leaks, evaporation, or long-term neglect in topping up. Insufficient coolant can cause the engine to overheat rapidly, damaging internal components, so it's crucial to pull over, check the reservoir, and refill. Always use the correct type of antifreeze and avoid mixing different types. Regular maintenance significantly reduces the likelihood of such failures.
