What to Do When the Blue Water Temperature Light on the Car Dashboard Is On?

[BradyMarie]

If the blue water temperature light on the car dashboard is on when you just start the car, it is a normal phenomenon. It will turn off after the car warms up. A blue light indicates that the engine temperature is low. If it remains blue all the time, there may be an issue, and you should take it to a repair shop for inspection. The blue light represents low water temperature, and it will turn off after driving for a while or idling for some time. The red light indicates high water temperature, and you should stop driving immediately. Due to a faulty water temperature sensor, the ECU may receive abnormal temperature signals, preventing the engine's large circulation from opening, which can lead to excessive engine temperature, rising water temperature, and even engine failure.
