I agree. Had the same problem on my 96 
Just pick up a aluminum radiator or even and auto zone one for not to much money and throw it in in a couple of hours. Better to do it now then risk warping a head or some other craziness!

It would not be difficult to attempt to flush it, however it would also be not likely to do any good...
Your car is 11 years old and in all probability the coolant has never been changed (I may be out on a limb here, however very few car owners actually change fluids--other than engine oil--at all). Time and heat destroy the corrosion inhibitors in the coolant and they stop inhibiting corrosion, the result is that narrow passages like those in the radiator corrode and clog.
There are acidic and highly alkaline chemicals used in radiator shops that might be able to restore some of it's capacity--however very often they are elusive an temporary fixes because the cell walls of the radiator have become so thin.
The bottom line is dick around with it, or just get a new radiator and be done with it...

Be sure to flush it really well.. Get your Heater core and Block lines off and run the hose through both until they come out clear. Then add your coolant and keep adding until it comes out yellow, then replace your line. Some guys half-*** it and just remove the draincock and refill the fluid. Quite pointless.
