I had a problem like this, i thought my radator was leaking casue there was damage to the fins on it, so i replaced it but the problem was still there. I checked and checked couldnt find anythign leaking. Then later on I noticed there was a small leaking comming from the heater control valve. So you might want to check that out and see if its leaking coolent fromt there.

Ok, I think I have figured it out....It isnt the HCV I dont think.. I looked at it after driving and all and no leaks! Heater works good too! I checked the bottom of the overflow hose from the coolant resevoir and it was wet with green coolant. I will get a new rese cap. One interesting thing happened the other day that I left out. At about midday I had added water to the resevoir and then drove to school and back. Later that night when I went back out to check the level, there were many bubbles in the resevoir
I know I didnt use soap water
So I guess the lost suction made bubbles in the resevoir? who knows. Im gonna get a new cap.
