That could be the problem. You can try to flush it yourself. If that doesn't clean it out well enough, have it rodded out. They will actually place the radiator in an acidic solution that will clean it out. There is a place near me that does all my radiator work. WHen I get it back, it is cleaned, repainted, checked for leaks, and looks and works like new. And all of this is done for around 40 dollars.
THat would be a good idea to try. If the hoses are old, it would be a good time to replace them too.
Let me know what you find.
