Bad radiator cap/not on properly, or too much cooling system pressure.

Well you aint suppose to run it with cap off.

That is normal. The reason is that when the engine cold the water does not circulate, after the engine begins to heat up the thermostat opens and closes, the water begins to circulate causing pressure in the radiator. You may have overfilled the radiator if so put the cap back on it and it will correct its self.
