Check engine light on..engine coolant was low..filled it..light still on with no obvious problems
Your check engine light must be reset. Many auto parts stores will hook up and check your codes for free. This will tell you why your check engine light came on. After receiving the code information they will often allow you to reset your check engine light with their machine. Hope this was helpful.
