I'm not sure. I'd bet there is someone here who knows.
Just wanted to reiterate myself here.The trans oil return line is the same for an SH ('09+) as well.
If there is any doubt try this:
The best way to determine which line on a transmission cooler is the return line from the radiator is to use the following procedure:
1. Start engine while engine is cold
2. Place transmission shift lever in drive for no more than 10 seconds
3. Place in Park, stop engine, and remove keys
4. Identify the oil return line by feeling both oil lines. The coolest line is the oil return line.
In the photo above, the return line for my 2010 was indeed the longer soft line but was connected to the rear positioned hard line on the lower driver's side and not the front as shown. I believe SuperRu's Foz was an '04 btw so that's prolly the difference otherwise it looks very similar to a '10 model.
Thank you so much for posting your pictures. I had mine mounted in an inferior fashion until I saw your pics. I was able to change my mounting and even got 3-point mounting accomplished, by also using the bottom left flange and additional hardware I had lying around. Very sturdy.I just wanted to add to this thread a bit and say how useful it was for installing a cooler on my 2011 2.5X.
This single post in another thread was also very helpful to me. Also, @SubieOutlaw 's bumper removal thread is helpful. The pictogram instructions included with my Sports grille were also somewhat useful.
I've attached some photos too; blue coloring denotes the original return line / the nozzle where the original return line was plugged in, and green denotes where I used the hose included in the B&M 70255 kit. As a side note, I trimmed and sanded the B&M brackets with a cut-off wheel to make them more to my liking.
I just unplugged the original return line from the nozzle, pulled it out from its guiding clips and attached it to the bottom of the cooler (line was trimmed). Then, I routed the new hose from the nozzle to the top of the cooler. Getting the new hose on the nozzle was very challenging - make sure to lube up the nozzle and new hose with ATF-HP (I used some of what spilled out into my pan).
I would love to reassemble my car; however, I was a moron and bought Subaru Coolant instead of ATF-HP (and everything is closed for the 4th, and all the dealers nearby are closed Sundays). The tranny dipstick said the fluid level was ok, but I did get quite a bit of fluid on my arms and on the ground. So, I'm leaving the front clip in pieces until I get some ATF-HP and run the car for a bit to make sure all my lines and clamps are holding.
Also, I would definitely recommend safety glasses / goggles (better) for this job, and it would've made my life a lot easier had I cleaned my car beforehand.
