All of a sudden while riding the AC kicked into cold and temp gauge returned to normal. As long as I was highway driving it seemed ok. When I got home, I checked the antifreeze it was low again; the overflow had flowed some. I filled the radiator and it kept burping; letting pour more and more in. I was saying to myself; I must have a head gasket problem or something, because out of all the antifreeze I had used. There was no antifreeze running anywhere external. Looked in Haynes and they mentioned the cap as a possible problem. So, later that night I went to buy a new cap. On the ride to get the cap, the car ran fine. Got up this morning and I said I going to drive it to work to see what happens. The morning trip was fine; with on sign of overheating.
What do you think this problem is? If it was the cap, shouldn't I have seen antifreeze sprayed under the hood. Could it have been a stuck thermo or water pump? What do you think?

Are your fans working?
One fan should come on with your AC as soon as the switch on the dash is turned. Is this happening?
Just for fun Jump power to your fans and see if they are playing the game?
Next I'd look at the relays that control the fans. On my Forester they were "swappable" with other relays so the test was easy.
My main fan was not working and my heat would do strange things...

Stoped a gas station bought antifreeze. When I went to put the antifreeze, I noticed the overflow tank was full and the radiator was pretty much empty.

You have a phase 1 2.5 engine. The highlighted text is a classic symptom of a bad headgasket. What happens is that the gasses from the combustion chamber blow into the coolant area and cause a vaporlock (as if it had not been properly "burped"), which can cause the heads to warp if not remedied quickly. My guess is that it is time to have the head gaskets replaced. If the waterpump were the problem, then you would not have gotten enough flow to shove the coolant out into the overflow tank. . .
