Low Coolant light

Thanks everyone. This is very helpful. Now I know where to focus when we take the car to the garage. My brother has been trying to oversee Mom’s car but really only knows how to SELL you a car. I know more about cars than he does - which should give you a good idea about how much he knows. I’m forwarding this information to him so if he takes it back to the garage he knows what to tell them to look for.
