Subaru's use something similiar to cool down the turbo when the engine stops. Essentially water still flows through the turbo (and a tank like this ) when the engine stops so, the bearings don't coke. In the case of the Subaru, the cooling system has 2 caps, one on the radiator and one on this tank. Both can feed the real expansion tank that's mounted to the side of the radiator.

exactly this system has two radiator caps as well and both the rad and this tank can feed the overflow tank. But even tho this car is turboed it has nothing to do with it. Thats kind of interesting that they do that to cool the turbo. Cool.
