I just replaced the radiator in my '98 (it was doing the same thing, including the corrosion inside the radiator) with a clearance unit from rockauto.com for $52.

Because it wasn't cooling efficiently, it was pushing coolant into the overflow tank, which was leaking. Thus I was having to add coolant every few days. Replacing the radiator fixed the cooling/coolant loss issues. <img src="/forums/images/graemlins/kewl.gif" alt="" />
