Had this same problem on the same vehicle. After a few trips to the mechanic, I decided to replace the radiator cap ($2.99 @ your local store). The problem was solved. It seems there is a seal on the cap that holds a vacuum in the colling system. This allows the coolant to flow into and out of the reservoir. If the cap is faulty (and from my mechanic friends, I learned that this happens more frequently than not) the vacuum does not hold and the flow of the coolant back into the radiator does not happen as it should. Hope this helps!
