If the fluid looks normal, proceed with the "burp" that was mentioned. Search this site and you should find some explinations of how to properly do this. I recently changed the thermostat in my 95 Sube, only to have overheating/no heater problems a week later. I thought maybe the water pump, but it didn't seem that wold be it. The fluid level looked to be normal, as I thought maybe I'd had a leak from my thermostat swap. No noticable leaks. My upper radiator hose was hot, but I couldn't feel movement inside. I squeezed it, and my radiator gurggled (the cap was off) and the fluid level dropped. I did it again, then proceeded to fill the radiator, periodically squeezing that upper radiator hose to gurgle out air.
I'm sure this method is the wrong way to properly get air pockets out of your cooling system, but my car has not overheated since then. This is my first Subaru, so I don't know if this whole air and "burp" business is a Subaru issue--I'd swapped out thermostats and flushed/refilled radiators on Detroit steel for years and never had an issue like this. The Subaru dudes and dudettes here can probably shed a lot more light on the situation than I can.

With the motor lower than the heater abd the thermostat on the bottom one has to be fairly careful to get all the air out.
I haven't really had a problem with it myself but I am pretty fussy about making sure all the air is out. After doing it once next time I'll modify the system.
