Over heating can be caused by many things. It could be a plugged radiator, thermostat (which you replaced), a timing issue (worn timing belt), a plugged catylatic converter (will have power loss), or it may not actually be overheating (bad temp sending unit sending a false reading to the gauge), a bad head gasket. Has the coolant actually boiled over?
