    Subaru claim their coolants are miscible; however, to take advantage of the blue's extended drain interval it must not be diluted with other coolant(s). It's not something I tend to worry about either way though.

When people say a "thermostat" is broken, it could be either the electronic component or the valve or both. Each problem can exhibit different behaviors. There's also a coolant control valve for the heater system that's operated by the dash controls, which can show a whole different set of issues.
    And where is this electronic valve?

    And the valve for the HVAC, do you mean a heater tap?
    They don't run a heater tap, coolant is constantly running thru the core.

    The thermostat has a valve attached to it... I don't understand your question. What's the purpose of a thermostat unless there's a valve? By definition a thermostat controls another device. Otherwise it's just a thermometer.

    Most cars have a heater valve to control flow to the core. Otherwise it bleeds hot air into the system even when you have the A/C running. I'm a car guy, but I don't know every single part on every car. If Subaru doesn't use one, then I imagine they use physical separation and ducting instead.

    What are you trying to get at here? I think it's readily apparent I know my way around a car.

    Was wondering where the electronic part of the thermostat is?

    I never said, nor implied you didn't know your way around a car.

    Installed the new Radiator, hoses, and thermostat. I went ahead and replaced the AC/Alt belts while I was in there. I made sure to properly burp the system as well once finished. The wrx is running great!

    No offense intended, I just felt like you were trying to test me. Sorry!

    The electronic part is where the wiring harness plugs into. That should be plastic, with a metal part attached to that is the valve, and that metal part will have a hose coming into it from the radiator, and from there the coolant probably goes into the engine block. Or there may be another hose that comes out the other side. I'm at work or I'd take a picture and tell you for sure. I'm basing this flow pattern on the standard one I've seen in other cars. The thermostat is usually located at the engine because that's the most critical component to cool in the car. If you look at the front edge of the engine you should see the wiring harness connect into a small device that's probably screwed right to the engine block and has a fairly large black coolant hose running from the front of the car into it.
