What to Do When the Car Temperature Gauge Lights Up?

[Charles]

Solutions for when the car temperature gauge lights up: 1. When the temperature warning light comes on, you should stop the car for inspection. Note that stopping does not mean turning off the engine; keep the engine running at idle to allow the hood to be opened for heat dissipation. 2. After stopping the car, open the engine hood and check if the coolant level in the auxiliary tank is normal. If the coolant is too low, you can add more coolant. If coolant is not available, you can temporarily use mineral water as a substitute, but make sure to replace it with new coolant afterward. For most car models, the water pump in the cooling system is driven by the engine. When the engine is turned off, the water pump also stops, preventing the coolant from circulating. At this time, various engine components remain at high temperatures, and without effective cooling, the engine could be damaged.
