Evap Purge Valve Location on XC90 V8?

[XC90V8Pearl]

Hello everyone,

So this is my first Volvo, but I've worked on many other European and Domestic brands. The XC90 seems well-built, and servicing it has been easy thus far. I like the power of the Yamaha V8.

Anyway, I've got a P2421 code that keeps popping (Evaporative Emission System Vent Valve Stuck Open), and I've read that the purge valve has an internal o-ring that can dry out and leak, causing failure. The problem is that I can't find the darn thing on my XC90 V8. I've read the forums and looked at the images from the parts catalog (Item #23 in the attached photo below, P/N 8653908), all of which say that it should be mounted on the fan shroud. I've looked everywhere - can't find it. I'm guessing that the purge valve is on the fan shroud for T5, T6, and 3.2 variants, but that it was relocated somewhere else on V8 models. Has anyone had this issue? Could you tell me where to look?

Thanks!
