no way the replacement gasket I got goes on the inside rim of the cooler. Fits fine on the outside ring. Are there two separate sizes?

I got it finally. It's not exactly the "fit" I was expecting for an o-ring. Oil leak solved.

Thumbs up O-ring sources

First, thank you for posting this excellent procedure. Second, I found the oil cooler o-ring (Dorman copy) at Rockauto for $4.50 delivered. ($2.77 plus shipping). The OEM Nissan part was available on Amazon for $10 plus shipping.

DidG35, I have the same observation about the o-ring 21304JA11A not fitting the inner ring and looks like it would fit the other ring (the one Jaygotboost cleans with a Q-tip on the picture). So you did install in on the inner ring? I just can't picture it..... I have a 2005 G35, but I don't think it makes a difference.

Found my issue. O-ring part number 21304-JA11A has 2 different size !

After struggling for too long trying to fit the O-ring part number 21304-JA11A bought on Ebay, I went to the dealer to but the same exact part.
After coming home, I found out the one fromthe dealer was actually smaller and fit snugly on the inner ring of the oil cooler. The one I bought from E-bay seem to only fit in the outer ring, where it doesn't belong.
The one from e-bay came was in Nissan OEM bag. just like one I bought at the dealer, not sure what happen....

I have to do this because mine is leaking. The dealer told me that it was the upper oil pan gasket and did mention the oil cooler gasket leaking.

Step 5 / Picture #1 shows where the old o-ring in Orange is currently installed and new o-ring goes in exact same spot . Qtip was just me cleaning the whole thing
