2006 trailblazer ss , 6.0l

While doing oil change I noticed an oil leak that is coming from what appears to be..behind the pulley on the power steering pump, , go figure my extended warranty just expired 2000kms ago.... is that just a seal behind the pulley that can be changed? it appears that the pulley is pressed on and the center is rounded so not sure how/if it unscrews? any info or links to diagrams would be appreciated, I've had my 06 SS since new and besides a pinion seal replaced (warranty) I've had no other problems, would rather attempt to repair myself if possible rather than bring to pirate dealer ..............very curious if any one else has had this same issue?? thx agn for any info , much appreciated

 

The pulley is pressed on and you need a special tool set to remove it. Are you sure its not a leaky hose?

Got this from the autozone website, hope it helps
