Thank you, Robert! I have not yet changed the fluid, still indecisive on which approach to choose, but am leaning towards making the hole in the trunk. Like you said, I'd likely want to change it again in 4-5 years and having the access through the trunk makes things much easier.

Gary, I emailed you about the hole through the boot, thank you! For the other methods I was trying to demonstrate them in a way which requires minimal additional disassembly. Indeed, removing the right side sway bar bushing and bracket would create more space for one of the described approaches. If I end up choosing that approach, I may as well take off the sway bar bushing, make life easier for myself :)

I'm literally in the process of planning this process on my 98 XK8 Convertible. Your video shows a great deal of detail and your experiments are really well thought out. My earlier car is a bit different to yours and getting access, even visibly, to the plug seems impossible. I have a hoist and even finding the plug is hard. I'm going to do the 2 inch hole with the grommet, I think. John Dee's video on To the Garage has given me enough confidence to do it. Even his solution to his positioning error makes it look better than Jaguar would have probably done if they had thought about it. Good video, keep them coming!

@@philcrowell7516 thank you for sharing and I am so glad to hear that my videos are helping out fellow owners! I'd say if your '98 vehicle has an electrical box which looks like John's and is located in the same position as in John's car, then go ahead with the 2" hole method.

@@philcrowell7516 See my comment above. I'll dig out the photos I sent to John many years ago. Unfortunately, he strayed from the location shown. Richard

@@philcrowell7516 Phil. I've emailed my photos to 2001JaguarXK8 but if you post up your email address here I'll send them to you as well. As soon as you get the photos you can edit your post and delete your email address. Richard
