Cooling system

[Traci818]

I have a 2003 T-Bird that is on it's 3rd thermostat, 2nd water bottle, and 2nd radiator hose, It still runs hot and the fan kicks in after driving 10 miles rain, shine, summer, winter. The dealership is trying to tell me that I shouldn't keep adding water and act generally surprised when it overheats after 3 weeks of me not adding water every two days... Anyone else having problems with the cooling system or have any ideas on what might be making it run so hot.
