My father is currently using my vehicle so I was not able to see exactly what happened and unable to check if any codes popped up. He told me that he started the car and the blue coolant temperature light was blinking for a while unknown how long. He also said the car was making in my guess warning noises. He drove the car about 13 miles shut it off and restarted the car a little later but the light is not on anymore and there aren't any CEL on. The temperature today is about 75 to 80 degrees. I understand that if it wasn't started for a while the temperature go down and the blue light illuminates for a short period. I never had it flash or blink before. Anyone have any ideas what it could be? Also car has only about 28k miles.
