Should there be pressure in radiator?

What does it mean when you have pressure in your radiator?
When the fluid in the cooling system heats up, it expands, causing the pressure to build up. When the radiator cools back down, a vacuum is created in the cooling system that pulls open another spring loaded valve, sucking water back in from the bottom of the overflow tank to replace the water that was expelled.
