The 3 pipes you’ve listed are plastic as that’s all JLR offer. I’d highly advise replacing with aluminum as discussed in this thread unless you intended to do this full service every 40-50K miles.

 

They are not, only the oil pipe. The remaining two are Jaguar Aluminium. Check the part no.
However, I did not find anybody here who would use them yet on a V6. But the plastic ones are the same for V6 and V8, so I hope these will fit. There were fit to F-paces and land rovers tho...

 

You're right! Apparently these were made by Land Rover exclusively for the 5.0 litre V8 Defenders. Good find!

EDIT: Hmmm, I've got the cheap knockoff pipes, no issues but seriously tempted to order these whilst the engine's still torn down...

 

Yea it's still a big mystery why?
Jaguar started out with Aluminum cooling pipes when the 5.0L came out then 2 years later they released them in plastic and then all the fun started. Although to be fair the first Aluminum pipes did have a failure prone plastic connector between them.

But in 2024 or 2025 JLR has again went back to the Aluminum versions BUT only released with LR part numbers. Almost all parts will usually have a separate LR and a Jaguar part number.
Glad to hear they did release them but still interested in what caused them to do this. Of course why did they stop there? We have the thermostat housing and the rear water manifold plus the oil cooler brick transfer tube in Aluminum in the after market. These have all shown to be failure prone as well.

Just purchased at the main dealer, in stock. Will post up pics later today.

Glad JLR waited until now to do this just as they've replaced the AJ with the TTV8 from BMW...

 

Do you have F-type? What engine if so? I think they should fit V6, as they fit V6 F-pace, and the plastic pipes in the same for V6 and V8... But I don't think anybody used them yet.

 

The C2Z18658 is not in metal by OEM, right? Is this part a a significant risk? I don't recall it being a problem here.

 

I've replaced this tube about 6 times, current one's alloy. Never had one fail but done as preventative. Nearly all other plastic cooling circuit bits have crumbled at some point on this SCV6 engine (the pipes everyone speaks of aren't the only parts which fail here). What does leak on this outlet pipe are the o-rings. Since new pipes come with new o-rings, for less than $20 it's best to replace the whole thing.

 

1. Replaced mine and have the rear crossover one waiting in the garage
2. decided the bare alloy is untidy
3. also converted mine to allow fitment of an6 fittings after the hose to the header tank popped off
4. ps the silicon was for a headlight on my runaround
   
5. 
   

 

If anyone is interested, Britcar.com asked Jaguar about the OEM aluminum pipes and Jaguar confirmed fitment for V6 F-type, so I have ordered them and let see.

 

Yes they fit. Quite heavy (and very well made) compared to the aftermarket versions. Picked them up yesterday. Main dealer said they were made available November last. Even their service department didn’t know they were available. JLR still
offer the plastic versions at a discount.

 

@Gasman2 Can you let us know where you got your metal rear pipe?

No JLR option yet I assume for this part?

Speaking of not having to remove the SC to replace the pipes, here is the procedure for the rear!

 

Got the rear crossover pipe from Ali express

 

Better than Ali express is simply buying the metal rear crossover from EuroAmp, which is what I put on my car. Perfect. No issues.

 

Here are the genuine JLR versions

 

@jahummer Thanks for the pics - I like how the new OEM aluminum pipes have cast logos and actually look good. Now ordering mine from a JLR dealer online. I noticed many "OEM"s on eBay without the cast J and LR logos, part number and QR code. Just the cut out JLR part label placed on top to make it look legit. One did have the cast logos but no part number or QR code.

What was your source for the aluminum C2Z18658?

 

I do have to chuckle
why would you think a part made in India is superior to a part made in china
Jlr oe stuff is shocking quality
mine is chinese

 

I hope this wasn’t a serious question. The country of manufacture has absolutely NOTHING to do with the quality of the part.

Genuine parts HAVE to meet certain standards of quality (and regulation) AND fitment. Aftermarket (in most instances) and KO parts aren’t required to and are often inferior.

 

Omg you actually believe jaguar parts are high quality
cheap tata steel
misaligned panels
brittle plastic clips everywhere
brakes that they got from the parts bin
I love my car but it’s a poor man’s supercar

 

That is a correct statement. Jag’s are economy cars. They’re not super cars and were never intended to be….

I’ve been repairing and building cars of many marques from Asia, Europe and USA for over 20 years. I speak from knowledge and experience. JLR vehicles have been some of the easiest and most reliable in their class to work on and own.
