Coolant Hose Replacement Supercharger Removal

Coolant Hose Replacement Supercharger Removal
2015 V6s AWD
I have had the problem that many have had- "low coolant" warning and can see a puddle of orange coolant sitting on top of the block under the supercharger. All the visible coolant pipes seem ok so I conclude that it's the troublesome y connector that runs off below the supercharger.
So I am going to try and DIY this job and would love anyone's input. I know a few people have done this or removed their SC for other reasons (coupler replacement etc). I have read a lot of threads.
My first question is this;
In the photo below, what is the steel pipe at the front of the supercharger and do I need to remove it? I have seen in his thread on fitting a polished SC cover UNHINGD seemed to keep it in place? perhaps by bending it a little to access the torx screws underneath? it goes down to a screwed coupling on each side.
I'm sure there will be other questions- I will write up the process properly when I'm done
Many thanks in advance!

Thanks madscott and holy ftype
I have made a little progress. Current situation:
So far I have discovered that the charge air cooler can indeed be removed without removing the high pressure fuel line- the fuel line can be eased forward just enough to allow the bolts to be removed and the cooler manoevered out.
I have also discovered that the thin plastic coolant lines on the top of the engine are very brittle (i believe @ozxfr had these cracked). I cracked one with very little forced during removal and then noticed that it was also cracked in the insulating sheath. I'm pretty sure these were not the source of my leak though as there was no leaking from these lines when the engine was running and also it wouldn't account for the large amount of coolant pooling on the engine block. They will need to be replaced though.
I am currently struggling with a few connectors- if anyone has any handy hints? the two main radiator hose clamps and another connector going into the supercharger inlet:
Thanks!!

Here is the detailed info for you on the SC removal for a V6. More detailed shop manual than the general stuff. It also includes additional items and info, so you can use what you need. I also included 2 other document links for you with general and additional information that may help. Some will be duplicate.
Good luck.

Watching this thread with interest, every time I read one if these posts I think I hope this doesn't happen to me and if it ever does there's no way I am replacing with the same parts materials. At the risk of repeating myself the materials used for these parts aren't suitable for the environment they are located in, if the replacement are the same materials then they'll likely have similar failure mode.

Those cracks before they broke completely could well have been the main source of your leak(s), just a tiny hairline crack can spew heaps of coolant due to the pressure.
Thing is, because they are right up high in the coolant system they stop leaking once the level in the expansion tank drops down to about 1.5 litres under full leaving about 3" in the bottom of the expansion tank, which explains why you get the "low coolant" warning but no catastrophic overheating. I twice drove my car a few kms in that state watching the temp gauge like a hawk but it never budged off the normal reading.

Thanks to everyone who replied- thanks therock of those files.
OzXFR- yes it's possible they are the cause. i'm in pretty deep now so I guess we shall see what lies underneath the charger and change the pipes over pre-emptively if they aren't cracked.
probably do the plugs too given i'm at 66000km
like you I had the warning but the engine didn't appear to be over heating.

Instead I get my parts from all over the world but usually the US or the UK.
I have replaced no coolant pipes or tubes other than that particular expansion tank tube and I got it from Britcar in the UK, see here: https://www.jaguarforums.com/forum/f...5/#post2322706

Thanks again for your replies- thanks for the info @OzXFR - i'll check out britcar.
Current status: all structures on the front and back of the supercharger removed:
Last two things before I can try and unbolt and lever this thing out:
1. Belt- does anyone have any tips on how to get the belt off?
2. Throttle body- does anyone know if this actually has to be removed? or can I take the supercharger out with the throttle body still attached? Hard to see if there are other things attached to the underside of the throttle body.
