C6 Part number reference document

Looking to replace my idler and ac tensioner but finding some conflicting info on OEM part numbers.
Does anyone have access to OEM part numbers?

I think AC tensioner is 12595289 and idler is 12568996 but not 100%

This page from GMpartsddiect.com shows two different AC belt tensioners, so I guess you have to pick the one in the diagram that looks like your part. The serpentine idler shown on this page agrees with your part number (although strangely, they refer to it as the air conditioning drive belt idler pulley). Note: These items are for my 2006 Z06. I don't know what car you have.

Are the bearing shot, or do you just need to R&R the bearing seals so you can clean the old dried grease out, and add fresh grease to them instead?

Hence keep the bearing greased, and they bearing will lost 100K no problems.

And to point out, even on brand new idlers, still want to pull the seals to add more grease from the start, since they are under greased from GM to cause them to go dry and wear out the bearing in less than 50K instead.
