Check The Vehicle Speed Sensors.

The Legacy has 2 Vehicle Speed Sensors (VSS): VSS1 is located inside of the transaxle; VSS2 is located in the combination meter assembly.

VSS1

1. Disconnect the electrical harness from the transaxle.
2. Connect an ohmmeter across the transaxle's electrical harness terminals 9 and 16.
3. The resistance should be 450-650 ohms.
4. After testing, reconnect the electrical harness.

1. Remove the instrument cluster from the instrument panel.
2. Disconnect the electrical connectors and the speedometer cable from the instrument cluster.
3. Connect an ohmmeter or continuity tester across the combination meter terminals 7 and 11.
4. Insert a small screwdriver in the speedometer cable drive socket.
5. Rotate the speedometer drive and note the continuity across the VSS terminal. Continuity should turn ON/OFF 4 times per speedometer drive revolution.

I've had the same problem all year. I've had four different mechanics look at this car - 97 legacy with 2.5. I've had the coolant seals replaced, the radiator cap, the thermostat, the water pump - all to no avail. I've realized now that it only overheats shortly after running sustained high rpm's. Recently the last mechanic mentioned the bleeder valve (I didn't know it had one and think maybe he didn't know either - not a subaru mechanic). Recently it overheated again (again sustained high rpm's - apparently more prone to produce air in the system), I sat the vehicle on an incline (raising the bleeder valve to be the highest point) and let the car warm up and run for half an hour. Now 300 miles and no overheat. I went through alot with this car to get to this point. Unbelievable.

if it overheats while your in motion then u can eliminate your fans, as your problem. and do you mean 5-50 thousand miles? id chech your coolant for hc contamination. most likley a head gasket

SOURCE: where are the spark plugs in subaru legacy gt

Subaru's are horizontally opposed engines. This means that the cylinder heads are actually pointed out toward the wheels.
If you look out close to where the engine and the inner fender meet, just a little in going back to the center, you will find two on each side on the 2.5 non-turbo. These have plug wires going to them.
On a turbo, the plugs are actually right in the side of the engine, going into the tops of the cylinder heads below the ignition coils which you remove first, to get to them. The same is true with the 3.0 engine.
