Drain coolant at the radiator drain plug. Loosen clamp on lower radiator hose where it connects to the engine, and place a pan under this area. Remove hose (hope you avoided the green shower), place hose out of way. The place you removed the hose from is the thermostat housing-- remove housing and replace thermostat, along with a new rubber sealing ring around the thermostat. Consider using new Subaru parts, or the best aftermarket you can find. Most aftermarket units are wrong temp (too hot), so swallow hard and ante up 35 bucks for the Subaru unit. Overheated engines are more money than a new thermostat. When replacing thermostat housing, avoid over-tightening the bolts. When done, refill with coolant (hopefully new), several times at the radiator, until it does not sink any more. Install radiator cap, and start engine, run until thermostat opens (about 2/5 gauge travel), top off coolant if required, and enjoy. Remember never remove radiator cap on a hot engine-- let cool 20 minutes or more.
