thermostat is bottom right as you look from front of engine...if not the stat it maybe an airlocking problem. have you openned all your heater valves up and given it a rev to push any air round? not familier with the approved subaru technique having not done this yet myself...but thats normal on other cars.

Have you also checked your oil/ headgasket as airlocking can result from headgasket failure. IS there any gurgling from the heater or loss of fluids? hopefully not!!

looks like it could be a thermostat problem, follow the bottom hose to where it meets the engine block, the stat is in the housing, the hose connects too.

be careful when removing the bolts for the stat housing that they do not shear. I personally also used new bolts when I did mine (Cant remember what size they are though, maybe m6 x 1)
It could also be down to a split in the radiator side core, this is quite common on the classics and the crack may not be evident unless water is hot and the system is under pressure. Are you losing water?
