Ive replaced the radiator thermostat and water pump but my car still over heats. What could be the problem?

Does it overheat if you turn heater on full blast? Are you losing any anti freeze over time? Is the system bled properly to insure no air pockets?

If there are no bleeder valves you just open radiator cap when cold and fill slowly until full then make sure coolant overflow/recovery bottle has adequate supply then when you get engine to temp again and let it cool again check overflow bottle for loss and refill to indicated line. Repeat until no loss is seen in overflow. If loss continues you either have an internal or external leak. The internal is either going into your oil or out your exhaust.
