I replaced my tank this Friday. I also replaced 5 of the 6 cooling hoses and new fluid. So far so good.

I too can't see it stressing the other components. People get failures of other items because it is time for them to fail. When you replace the tank, which was losing pressure, and leaking, you basically close the weak point in the system. What happens then, is the hoses and other stuff have to start working again at full pressure.

I think the component failure is when those people neglect the leaking tanks, and replace them when they leak like the Hoover Dam. Like all the fluid emptied out. The hoses are old, and now they are relaxed, because of the low pressure, rubber does have memory. Then all of a sudden, new tank, the cooling system is at full pressure, and this shocks the other components.

Replace your dripping tank right away, and I think you should be fine. Replace the expansion tank fill cap as well. Only reason I replaced the hoses, is because I am insane, and do preventative maintenance way ahead of time.
