JLR Dallas has the "Jaguar" branded alumium replacement y-pipes.
I just paid full retail to have the dealer replace all the coolant hoses, y-pipes, water pump, thermostat, etc. on my 10+ year-old 2015, one owner (me), 12,877 mile, V8S. My 10-yr old "Y" pipes were perfect with no leaks. Had sepage at the water pump pulley and whatever you call that water manfold plastic thingy that mounts on the back of the engine. I have a video but the file size is too large to share here. They only kept the car for 2 days.
If you want to know much it costs to do at the dealer, here's the breakdown.
Parts: $2,038.85
Labor: $2,915

 

Wow! I just did mine on my 2019. Like you, pipes were fine. I bought a kit online with the pipes, new water pump, and metal thing to replace the plastic one on the back of the engine. The aftermarket kit was just under $500. I did it myself and while it wasn't a super difficult job, it wasn't exactly easy. Good for you for getting that done pro actively.

 

I've seen a lot of people saying getting the supercharger off takes a lot of muscle and willpower. How was your experience?

 

They are correct. The lid was stuck on pretty good. You have to get rougher with it than you'd like to. The supercharger was also stuck pretty good. But they do come off.

 

Ouch. I had the labor quoted from a shop where I have had previous work done. It was NOT a JLR dealer. Labor was $1100. Said he was happy to let me supply my own parts.

 

I used an engine hoist to lift it off after some dead blows.

 

For the DIY guys, how long did it take you roughly to do this? I am thinking about doing this this winter when the car is dormant, is the reason I am asking.

 

It took me 2 months. LOL. I just worked on it when I had time and we had a few trips and family issues during that time. I would say if you stayed on it, you could knock it out in a weekend. I also sent off my supercharger and had it rebuilt with new rotor packs.

 

I think the biggest variable on the supercharger removal is whether or not the car is AWD or not. As I understand it, AWD car’s hood vents are spaced more advantageously for drainage and the supercharger is therefore not too corroded/stuck to the manifold.

 

I did it total in about 6 hours, but over a few days as I was stalled waiting for parts to arrive more than the work itself.

In one case, the SC gasket set I ordered had one of the intake gaskets missing so I had to order that over while the car was disassembled. After the first one, I really believe, with all the parts first, and working on my own with no help (helper) I could make it in 4 hours. Also, when I did mine I changed the water pump and replaced the oil cooler in the middle of the valley so a little bit extra labor.

 

Same question to you. How did you get the supercharger off and how difficult was it? More than a couple of people have said they used an engine hoist, which would make me want to tap out...

 

a pry bar to get it loose then lifted it off. Each one can be different, I assume. Mine just was not as bad as some that I've read about. I have an engine hoist but it didn't even occur to me to need it for this.

EDIT: I probably should add - I'm 6'5" and have long legs and arms. I'm guessing that could assist in reaching across the engine bay and lifting the SC up and out. Same for replacing it. Not meaning to make this a physical contest, but some of it probably matters.

 

I used the hoist to apply controlled pressure to break the seal. I like minimizing the risk of prying on aluminum components with steel.
