Overheating?

So I bought this 99 f-450, truck runs good, if you let it idle it will build temperature and peg the needle fairly quick.
So I pop the hood and check the coolant bottle.
Empty.
Unscrew the cap and let the pressure(vaccum?) off, and it fills the bottle back up, takes the temp down on the gauge instantly.
Im Baffled.
Any thoughts would be greatly appreciated.
Thanks From a long time ford fan

Is this a daily occurrence? Or it just happened once? Any signs of coolant leakage?

That's a weird one... is it pressure or vacuum? Are the radiator hoses collapsed or expanding?
