I have a 2014 XKR. Vin block is B53XXX. It's got just under 50k miles on it. I'm getting ready to take the supercharger off the car so I can get into the cooling system and replace plastic parts with metal. The car isn't driveable because there's a bad enough coolant leak to have steam coming up off the car after it starts warming up. There's also coolant spraying off the serpentine belt(s), so I know that I shouldn't be driving the car.

Anyway... if I'm going to have the supercharger off the car, I figured I should look at the supercharger isolator to see if there's anything that needs to be done, there. Here's the problem... I look online and keep seeing snouts (that I may have to replace) for up to 2013 XKRs. I couldn't find anything that's for my 2014. I went to my local dealership, and they told me my snout was C2D58056. If I punch that part number into any of the official jaguar dealership parts pages, those pages say the part isn't compatible with my 2014. I haven't started tearing anything apart, yet. I'm trying to get a parts list put together ahead of time so I can check parts and add to a cart as I go.

What part do I REALLY need for a 2014 XKR supercharger snout?

 

The snouts are all the same for the 5.0 litre, 2010-2015. But if you're just replacing the isolator, you don't need a new snout. Many threads on these forums about this. As for your leak, sounds like the water pump but there are many oparts to the cooling circuit which fail and need replacing in general, could be oil cooler pipe, crossovers, throttle body, etc. Again tons of threads on these forums.
