Coolant is supposed to be replaced more often than every 4 years. So don't
neglect to do it soon.
If you don't have a dealer do it, you will need the "coolant conditioner"
that is supposed to help mitigate outside gasket problems. (Especially on
that year of Subaru).
You can get it here:

All Subarus are suppsed to have this now.
Aside from that, (as the other poster mentioned) there are quirks to Subarus
that need to be addressed during the coolant change process.
