When it starts leaking. Do you have the metal intake type or the plastic (http://ironlizard.blogspot.com/2005/11/gm-v6-and-coolant-loss.html) in that year? (I completely forget)

The best time would be to wait until it starts to leak. However, if the gaskets worry you they can be replaced anytime as a premptive strike against leaks. Just depends on how much time you have and whether you want to spend 8 hours bent over working on your car. Although it beats being stranded without a car if they go unexpectedly.

Ouch. The usual problem with these cars isn't so much going to be the gasket leaking, it'll be the manifold melting internally. I don't know if you checked the plastic link in my last post, but you might want to. When they go, it's a PIA. It happened to me at the worst possible time (really, when is a good time?). With those miles, I wouldn't worry yet but when you start losing antifreeze without any other leaks, it's time to start thinking about tear down of the upper end and maybe a new manifold.
