What does it mean when the thermometer red light on the dashboard flashes?

This is the coolant temperature warning light. Relevant explanations are as follows: 1. Pull over to a safe area: When the coolant temperature warning light comes on, you should stop and check, noting that you should stop but not turn off the engine. Park the vehicle in a safe area and do not turn off the engine. Let the engine continue running at idle speed and open the hood to dissipate heat. If you see steam coming from the hood, it's best to observe first and not open it hastily to avoid burns. 2. Normal coolant temperature: The normal engine coolant temperature should be around 90℃. If it becomes too high or too low, or rises or drops rapidly, then there is a problem with the vehicle's cooling system.
