What warning signs appear when a car is low on coolant?

When a car is low on coolant, the following warning signs may appear: 1. A thermometer-shaped indicator resembling a key; 2. A symbol shaped like a kettle. The primary function of coolant is to ensure the proper and efficient operation of the engine by circulating within the engine's radiator, providing anti-freeze, anti-boil, anti-rust, and anti-corrosion effects. Most coolants are colored red or green for easy identification of leaks or to distinguish them from other engine fluids. Precautions for replacing car coolant include: 1. Measure the freezing point of the coolant; 2. Prevent leaks during replacement; 3. Avoid injury from hot coolant spraying by ensuring all old coolant is completely drained; 4. Ensure the new coolant is filled to the standard level; 5. Wipe off any residual coolant from car components; 6. After completing the process, check for any leaks.
When the car's coolant is insufficient, the most obvious warning is the temperature warning light on the dashboard, which usually appears as a thermometer icon or displays the word 'High Temp.' I've noticed that while driving, if the coolant level is low, the cooling system becomes ineffective, causing the engine temperature to spike rapidly and directly triggering this red light to flash or stay illuminated. The temperature gauge will also quickly rise into the red zone, indicating an overheating condition. Sometimes, this is accompanied by steam coming from under the hood or the car struggling to accelerate, feeling like it lacks power. As someone who has been driving for ten years, I recommend that as soon as you see this light, immediately pull over, turn off the engine, and check the coolant reservoir—located in the engine bay. If the level is below the MIN line, it means it's insufficient. Never force yourself to keep driving, as the engine could seize and be ruined. Make it a habit to check the coolant reservoir every month to keep it topped up and avoid unnecessary trouble.
