I'd say the radiator is clogged or close.  This usually occurs when someone puts stopleak in the system or mixes coolant types.  Removing the radiator fan temp sensor will usually show goop on the inside if this is the case.  I would remove the radiator and take it to a radiator shop to have it flushed/flow checked/leak tested for about $30 or so.  If it's bad, get a new one for $200, yours is now 15 years old and you don't have a clue what's been run in that thing before you bought it.
