My radiator overflow reservoir is low or empty and the check engine light comes on. When I refill it, the light will go off.

There is a sensor in the tank to read the coolant level, it will turn the light on to warn you, once you refill it then the fault goes away. The check engine light will come on for sometimes hundreds of codes. My next question would be, where is your coolant going.

I don't know. I haven't noticed any leaks. I'm now hearing noise from the right side around dash when heat is on.
