Fan clutch can be replaced while laying on to of the engine. I've done it twice. It's not fun but it's the only way to do it that I know of without removing your radiator.
Reading through this thread you basically have two things you can try. The easiest by far is replacing the fan clutch. The ACDelco unit is about $110. I wouldn't buy a cheap one from a parts store because they are generally a generic unit and there have been a lot of people complaining that the cheap ones don't come on at the right temperature. Your last choice is to replace the radiator.
Personally I think you might be a year or two by replacing just the fan clutch but in the long run you will have to take the radiator out and at a minimum have it cleaned but if it were me while it's out I would re-core it which means you don't have to worry about it again for a LONG time!
