Also, the dealer will not "service" the supercharger gear oil when they replace the snout. Tell them you want the oil drained and refilled with new. They will most likely charge you for the oil, but have them do it.
If you have the 5.0 engine, you can only drain the oil by removing the charger.
Call them and ask before the day you plan on having it fixed, because most likely they will not stock the oil.

Thanks for the heads up. I left a message with the service advisor to do the supercharger oil and coolant pipe while they are in there. I only have 30k on the car, but this seems like the best time to do it.
I’m sure they will use the same Jag coupler.. but since it’s the dealership, I’m sure they won’t install anything new and improved.

Thank you Bart - I was about to post that! The manual clearly states there should be some play (though obviously only 5° counter-clockwise and 20° clockwise), so people maybe shouldn't be so quick to label the coupler as screwed as soon as a poster mentions any play.
With that said, we know these spring couplers go bad and eventually need replacement, though if I'm honest, I'd probably wait until mine at least felt a bit loose before I changed it out. You can get solid couplers on eBay, which I fitted to mine.

I got to see the new snout over the weekend when I dropped the smaller pulley off so that it can be swapped over before I take the car in. As suspected it came with the older style coupler although I see that the design has been improved because the end of the spring now sits in a small metal enclosure so shouldn't wear the same as the original ones did.

Do you happen to know what the part number is for the Jaguar supplied solid coupler, please?
