Yesterday while heading to work, a 30 minute drive, and within the last 5 minutes, my radiator light came on.
When I left work that night it came on a few minutes after I started home, and then a quarter of the way home my Check Engine Light came on. Before I left work I checked my fluids and I was good, but my radiator cap was not screwed on correctly and sprayed fluid all over the interior of my hood. Not only that but the radiator fluid in the coolant tank was filled up to the brim, way passed the full mark. When I checked it this morning, it was back down to where it was, but when I turned over the engine again, both lights were still on.

I'm thinking there might be a bubble in there, but I have no idea honestly.

 

From what you described, it sounds like it may have an air pocket in the system. That radiator light isn't a fluid level warning, it is a temperature warning. Take it somewhere to have it checked out before you keep driving it and blow a head gasket.
