It's on the pump in the first picture I posted in the thread. But here is exactly where I got mine.

So I just got around to doing this after getting a code and reduced performance error for cooling performance. I pulled mine out and have all the parts, but my pump looks WAAAAY smaller than the new one. Is it possible my 2009 xf SC is very different from your XFR? Should I replace it anyway?
Honestly, I got in there and only after I got everything taken apart did I see that my main, mechanical pump has some dried coolant that makes me think it's leaking, which is probably what is causing the error. The pump I'm replacing is probably completely fine, so if I need to just put it back together as is, that's probably ok.

Unfortunately, now I have to replace the mechanical pump, since that appears to be the actual problem.

Good point, and one I was unaware of since the (my) 5L cars only use the one electric pump.

Both pumps are in the same location, if you're looking from the top of the engine bay down, the heater pump is above the chargecooler pump.
On the X350 XJR and the STR, you have better access to the chargecooler pump from underneath. The chargecooler pump is mounted at the bottom of the radiator.
I'm 99% sure you've got hold of the heater pump, not the chargecooler pump.

Well Crap. Guess I'll be tearing back into it when I get back in town. Thanks for letting me know.

Does this mean I need to take the radiator out or is it pretty self explanatory once I get the skidplate off from underneath?
