The water pump has a plastic impeller, which is commonly separate from the pump's shaft. It's easy to check if the pumps builds up pressure or not by squeezing the radiator hose while rev up the engine, if no sudden pressure will be present, the pump failed.
There are other things could cause overheating, but this is one of the most common one.
