So, following my lovely and well written service manual that i snagged from one of the Subaru forums, this is my swap. I'm writing this guide for personal record and reference and also for those who are new to doing tedious tasks as such.
It hurts me everytime i see this
Anyways preparing my garage for heavy maintenance
Jack up and place vehicle on 4 jackstands
Open hood and support with stay in the maintenance position
Release built up fuel pressure by disconnecting fuel tank connector located under rear bench on the right side under sound insulator. Start the car and let it run until it stalls and then crank for additional 5 secs to burn as much of the fuel from the lines as possible. Turn ignition switch to "OFF" and remove key.
Disconnect and remove battery from vehicle
Drain coolant via drain cock located at the bottom right(vehicle's right) of the radiator
(I dont have a picture of the drain cock location)
I had to share this. This has to be the worst drain cock design possible. As you rotate the drain cock to drain coolant, it shoots coolant everywhere depending on the orientation of the cutout. Maybe I don't know how to use this drain cock properly but i made a huge mess.
Disconnecting 2 fan connectors and the outlet hose from the engine block located on the bottom left side of the motor.(I found this easier than to remove the hose from the radiator like the manual said. BTW I'm new to Subaru and i have to say i LOVE where they put the thermostat)
Forgot to take pictures but i can always edit them in.
Remove V-belt Cover.
Remove Upper radiator inlet hose from radiator
Remove 2 radiator upper brackets and remove radiator from vehicle
Depressurize the high pressure A/C line and remove high and low A/C line from compressor. (To properly depressurize the high pressure A/C line, the manual calls for a attachment hose which i did not have on hand. Instead, I ziptied a ziplock bag(or something equivalent to keep refrigerant from spraying throughout) to the high pressure fitting and used a small allen key(or something small and blunt) to release pressured.)
WARNING WARNING WARNING:
"Problems from inhalation of R134a depend on the dose; small amounts will not harm the lungs. Acute inhalation of larger amounts becomes more worrisome, causing symptoms including temporary nervous system depression, with accompanying drowsiness, lethargy and insensitivity to pain. Prolonged breathing of vapors can cause cardiac irregularities, unconsciousness and death."
WARNING WARNING WARNING:
I had my garage fully ventilated by having a stream of air flowing through my garage. I also took the extra precaution and held my breath when i was depressurizing the system and only took a breath when i was completely outside of my garage. I know i am going to catch some flak for doing this method but it works for me
Disconnect the MAF(Mass air flow) sensor connector and remove air intake system. I did forget to remove the massive resonator box which i later removed.
Remove 3 vacuum hoses from the filter canister and remove the canister and its bracket from front right side of vehicle. Dont forget to mark which line goes where to save the hassle later on.
