thats a good question cause my light comes on everytime i start my car but once i start moving it goes away !
I work at a shop that does Rad flushes and coolant shouldnt look like that so to answer your question, no most likely the previous owner never flushed out the coolant lolI’ve noticed that I have to over fill mine a little bit to get the light to go away. My coolant is almost oil black. So yea, gonna change that pretty soon LOL. I wonder if the first owner ever changed it..
