I discovered the X was built in 09, and sold in 2010 as a 2010 model. I know most of the manufacturers do this in he later part of the previous year, but I do wonder if the coolant leak is still an issue with this model.
A) welcome
B) I would bypass to be safe. Or at least look into Rad's model number to see if it's updates.

21410-EA200 [seldom referenced, but may have been installed in some very early 2005’s.]
21410-EA205 [2005 – either 2/09 or 8/09. Listed on some parts websites as P/N
21460-EA205. There is some confusion as to when these were used. Some literature states until 2/09 and other literature states 8/09.
P/N IS ASSOCIATED WITH SMOD. ]
21460-EA215 [2005 - either 2/09 until 8/09, see above. Listed as discontinued and replaced by 21460-9CAOE on Nissan parts websites.
P/N IS ASSOCIATED WITH SMOD]
21460-EA265 [production dates unknown other [MENTION=3593]Surf and Snow[/MENTION]'s Xterra built in 04/05 and my own Xterra built in 09/05.
P/N IS ASSOCIATED WITH SMOD.]
21460-ZL11A [8/09 through 2010 model year,
isolated reports of SMOD, however I have not been able to verify.]
21460-ZL31A [production dates unknown. Listed as discontinued on Nissan parts websites , no known reports of SMOD.]
21460-9CAOE [2011 – 2015 model years – no known reports of SMOD]
This is the part number for the most current version as of 11/16.
I think one can be confident that the risk of SMOD is nonexistent with the
21460-9CAOE radiator, and probably also with the 20410-ZL31A radiator. It appears that there is some risk with the 20410-Z11A version, and the 21410-EA200, 21410/21460-EA205, 21460-EA215, and 21460-EA265 versions are ticking time bombs."
