Just purchased 2 days ago from private owner. After driving 2 days, temp light came on, fluid low in bottle. Added 50/50 mix coolant, now temp light comes on blue?
Manual states that when the fluid is cold it will show up blue then as it wanrms up it goes away. a normal function. It's in the owner manual somewhere.
The blue light indicates cool coolant. This light should go out when engine warms up. If not scan to see if it has a coolant temp sensor code, but my light shuts off when engine gets warm. I hope this helps!
