Question about 2007 Chevrolet Cobalt Coupe
When you take the lines off the calipers, put a small screwdriver between the front brake rotors and the back pad and gently pry the piston back into the caliper. use a larger screwdriver once it starts to compress. All of the fluid should come out the back of the caliper. Catch it in a pan. Once both calipers are collapsed, hook the brake lines on the calipers and gravity bleed the lines thru the caliper bleeders. make sure to keep the reservoir full while bleeding. After bleeding, you will need to pump the brake pedal to bring the pads back to the rotors. refill the reservoir after doing that.
On the temp gage, open the radiotor cap, if you have one. run the engine until it is hot and the thermostat opens--you should be able to see coolant flowing inside the radiator. Fill the radiator and keep it full if it goes down any. I think it should bleed itself like this, but look around for any bleed ports either on top of where the hoses connect to the engine or else they might be along the hoses. There is no mention of coolant bleed ports in the manual.
If this doesn't fix it, get back to me.
