thats a bit like late model SG foresters. They have 2 pressure caps. one on the top of the radiator, and one on the header tank. Where as early SG only has the one cap on the header tank.
With setups with 2 pressure caps, its VERY important to have an equal or lower pressure cap on the highest point in the system. If you have a higher pressure cap at the highest point, you can get situations where any air in the system will not naturally bleed out.
