The X350 'HOW TO' quick links thread near the top of the home page of this X350 forum has a lot of helpful links. For example, you can download the Workshop Manual in six sections at these links:
X350 Workshop Manual Table of Contents
X350 Workshop Manual General Information
X350 Workshop Manual Chassis
X350 Workshop Manual Powertrain
X350 Workshop Manual Electrical
X350 Workshop Manual Body & Paint
The alternator replacement procedure is in the Powertrain section and note that Jaguar refers to it as the "generator." You can search for this term using the Adobe Acrobat Reader search function, which you open by pressing Ctrl+F or Cmd+F.
Cheers,
Don

I replaced my alternator in a 2005 XJ8L about three months ago. I followed the instructions in the service manual and all went well. The only issue was getting a beam strong enough and anchor points sturdy enough on top of the strut perches to hold the engine while the right engine mount was taken out. Once I got the engine supported properly it was just following instructions and very straight forward.

@RoonieQ: I used 2x4 pieces of wood cut to size with slots in them to fit on top of the strut perches. Then I put a brace on each side going forward to the front of the car to keep the support from rolling forward.
I lifted the engine by putting a floor jack on the sides of the oil pan and lifting slowly. The chain was attached using a bolt to the engine lifting slots on top of the block. The metal cross bar was very thick and strong, the first one bent too much and I had to find a stronger one.
The most challenging part was making the brace to hold the engine, other than that there wasn't any surprises. The service manual was spot on in the way to replace the alternator. Hope this helps.

On an engine with a plastic sump you might want to position the sling ahead of or behind the pan or use the chains in the traditional method.

Thanks to you guys, I was able to do this. I had my alternator fail on me a couple of weeks ago; so after calling the dealership for giggles pretty much to see what they’d quote me, I figured I’d try what others here did, raising the engine a bit from the bottom & getting the alternator out.
I had a couple of guys help that wanted to do it; I more so did all the WATCH work! Haha
We removed the Coolant reservoir & hoses, then the radiator fan & harnesses; then the serpentine belt, which had been on there since I got the car 4.5 years ago & much longer than that, all the the shroud from the under body, the right wheel & the wheel well; we were then able to get to th alternator from the front & back underside; we removed the motor mount, stuck a low profile jack under the oil pan & gave her a lift.
We were then able to get to the bolts to the alternator & slide it out towards the front where the gap was via the removed fan...
As for the alternator, I found 1 from a reputable & trust worthy seller on eBay that I’ve purchased from before; it was off of a wreck 2007 XJ8L with only 40,000 miles on it; I paid a mere $59 for the OEM barely (to me) used Alternator! The Serpetine belt was $29; Labor was $12.02 via Pizza
I did have to replace my battery, but that was still under warranty & I had to by coolant, & get that dialed in which took a couple of hours.
Oh yeah, the dealership,,,,,,,,,,,$1380 is what they quoted me for the Alternator & labor. Another specialty shop here quoted me $1,000, so I think I did pretty good!..
