SC400 coolant reservoir replacement
Is there any reason I couldn't use a $20 generic overflow tank? It's such an easy replacement I figured that if that was all we needed there wouldn't be such a market for 20 year old brittle plastic overflow tanks on ebay.
Plumbing is easy of course. The only part that makes me pause is that the stocker is obviously pressurized, thus the radiator cap, while a regular overflow tank is just a big jug of coolant that holds no pressure.
What am I missing?

That's what I was worried about - that it was more than just an overflow bottle. It's actually an integral part of the radiator.
Subarus (at least I know the 2.5 turbo does) use a separate reservoir that is made of heavy plastic like our OEM piece. Even if they aren't any cheaper on ebay (haven't looked) they are 2 decades newer so they won't fall apart again.
The easy permanent fix is a new radiator from a newer model that didn't use the tank. I may do that since it's time for new hoses anyway.

Don't the later SC400s use a radiator without the extra piece? I thought they had a "regular" radiator / flimsy overflow tank setup, maybe 98+ cars? I'm not too proud to have a generic overflow bottle under the hood if that's all I'd need after a new radiator.
