2003 Xterra Coolant Leak

Hello All,

Recently I started to get a coolant leak under my throttle body on my 2003 Xterra. I purchased it used in 2005 and had the wax pellet replaced user warranty in 2006 and was thinking that it is probably suspect again. From my research online it sounds like it is the culprit for the leak, however I couldn't find any pictures online or how-to's to confirm and was hoping you gents might be able to help me out? I snapped a couple pics below. Also is this a DIY job where I can get the parts at a local auto-parts store or is this something I will need to take it to Nissan again? Any information you could provide would be greatly appreciated. Thanks in advance for your help.

You remove the part with the corrosion and use a rubber O ring to stop the leak.
Everyone's does this at some point!
You can do it on the truck, but it can be a PITA. Some remove the throttle body to do it on the bench.
