What are the best cast aluminum coolant pipe upgrades for a 2014 XJ V6 supercharged engine? I see a lot of options and am a bit wary of the ones with names like Chinese made Amazon products.

 

I used the one that came with the Euro AMP kit. It was good quality and has not leaked.

 

2018 and 2019 XJs got upgraded seamless plastic pipes. Any Jag/Land Rover dealer has them.

 

Looking for the durability of aluminum.

 

Yes and JLR has now released them in Aluminum so if you want factory parts you can get them in both plastic and Aluminum.

A number of threads going on now about this new development.

Clubairth1, My Jag/Land Rover dealership parts dept denies any knowledge of JLR having aluminum coolant parts. Any suggestions on how to push the issue with the dealership or find those JLR parts. If it's available yet, I'd love to buy an approved rear crossover pipe from JLR rather than go through the cleanout refurb you did on the Chinese two piece to make sure it wasn't blocking flow.

 

I just read the previous message about the JLR aluminum coolant pipes so I called my local dealer. Now,mine, is a 2012 XJL x351 N/A (non supercharged) and I was told
that for the N/S models like mine,they have not been made yet. So, I bought what I could from Euro Amp but they are out of the crossover pipes , and am also wary
of the Chinese versions sold on ebay and Amazon. If anyone has a recommendation for good quality pipes for my n/a model please let me know.
Happy Motoring

Yes just the SC engine so far for the pipes from JLR. Have heard the NA versions "might" be released by one of the after market suppliers.
JLR has NOT released Aluminum versions of the rear water manifold. So If you want to change that part which I did. It will need to be after market.

Here is a picture and they are marked with JLR in the casting. But there is some confusion again?
Hard to see the part numbers.





They do look good. Part number stickers are marked with "Made in Germany". Part numbers are LR092992-A and LR090630-A

There are these out too? But marked with "Made in India" on the parts sticker. Part numbers are LR186859 and LR186917.
You can see the Aluminum pipes in the plastic bags these stickers are attached too.




The India version installed. Note that LR versions cap the front opening from the factory.





So not sure which numbers to use? Possibility that any of these might be counterfeit parts?

Where do I purchase these?

 

Run the part numbers in any search engine and take your pick.
