Yesterday assisted a friend with a service on his MY97 Rex.
Everything went well -except the coolant replacement.
Unfortunately created an air lock in the system during fill -resulting in mega over heating and a disfunctioning heater.
Apparently Subaru reckon that the filling of the header tank should be VERY VERY slowly to avoid air in the system.
They use a modified funnel , that restricts the flow to a trickle.
I drilled out a cork and rammed into a funnel to restrict the flow.

No problem with mine which I did it myself,drain old coolant,new coolant in,till coolant level is full to the filler neck,start up the engine and top up as required with engine running.Then drive for 5-10 mins and check the coolant level after 2 hours after shutting down the engine,which you still require to top up again.As a precaution check the level again first thing next morning before starting the engine.

I had an air lock when i changed my antifreeze,in the end i left of the cap and slowly poured the coolant in until the heat came through on the heater,then i put the cap back on and left it idling for 10 mins.
