Dude...theres SUPPOSED to be a vacuum in the cooling system.
Youve got a set amount of liquid that has been heated up. As it cools back down the volume that it occupies decreases and since the system is a closed system (so long as the reservoir is full) a vacuum is created. Havent you ever sat by and watched while the car cools down and draws fluid from the coolant reservoir?
Anyways there is nothing wrong with your car other than the need for a new upper radiator hose. Radiator hoses should be firm enough not to deform under pressure or vacuum.
