What car / engine is it? If it's the V8 it could be air in the system - this is a known problem. I think we need more info before anyone can offer any help.

From what little you have told us its more likley to be a fured up radiator, if the water is restricted to much it startes to over heat in the engine and just blows the rad cap. I had this trouble, I tried de-scaling it, and water seemed to pour straight through the rad, but it was not enough to stop the pressure build up. new/refurb rad cost me £40.
