Make sure the cooling fans work. If the radiator is really dirty it will still overheat even if everything else is good. Try a back flush kit. I think Prestone makes one.

My experience was that the gaskets were bad and had to be replaced. After having them replaced, problem has disappeared and have put another 100,000 miles with no overheating.
