What does it mean when the car's water temperature light flashes?

When the water temperature light on the car's dashboard flashes, it is because the coolant temperature has exceeded the specified value. Below is relevant information about the car's water temperature light: 1. Icon color: The water temperature indicator light is primarily yellow and is used to display the temperature of the coolant inside the vehicle's engine. For models without a water temperature gauge, the coolant temperature is indicated by the color of the light: blue indicates the water temperature is too low, off indicates normal water temperature, and red indicates the water temperature is too high. 2. Indicator light stays on: When you turn the key and the vehicle performs a self-check, the water temperature indicator light will illuminate. After starting the car, the light should automatically turn off. If the light remains on after starting the car, it means the coolant temperature has exceeded the specified value.
Last time while driving, my temperature warning light suddenly started flashing, which made me really nervous. I immediately pulled over and turned off the engine because it indicated possible engine overheating. Upon checking, I found the coolant reservoir was nearly empty, likely due to a leak or insufficient evaporation. I added some emergency fluid but still drove to the repair shop for a thorough inspection. The mechanic said the water pump seal had aged, causing a minor leak, and replacing it fixed the issue. A flashing temperature warning light should never be ignored—engine overheating can lead to deformation or even complete failure. It’s important to get into the habit of checking coolant levels monthly, especially during hot summer months. Also, don’t forget to have the entire cooling system inspected during regular maintenance to avoid such scary moments in the future.
