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.
