So I currently had a car run me off the road and my two driver side tires were blown out because I ran into a ditch. Since then I have replaced both tires. I am now having an issue with my engine running hot. My coolant temp was 240 after driving a few miles and my milage indicator said engine cooling system on. Never seen it before. Wondering if this could be a thermostat issue. It's an 07 cobalt 4 door ls. Now my coolant is actually reading blank.
