Aluminum Replacement for OEM Plastic Coolant Pipes
An aftermarket fix is now available for the failure-prone OEM cooling system plastic pipes used in the 3.0L and 5.0L Supercharged Engines.
I ordered these aluminum replacements from Ebay for but haven't received them yet. They're for my 2013 XJ that has the 5.0LSC engine. Even though my OEM plastic pipes are still OK, I'm going replace them to avoid problems.
I didn't post a link because the vendor I bought them from is now out of stock. Search Ebay for other sellers, there are several.
The factory should have used aluminum, not plastic.
I've seen this aluminum replacement for the 5.0 Supercharged engines for awhile now. I'm soooo annoyed they don't have a replacement for the many 5.0 non supercharged engines. I'd jump on one regardless of cost. I wonder if it's production is around the corner and will come out right after I replace all my plastic coolant parts!
Surely these are suitable replacements for ALL JLR 3 and 5 litre SC engines.
EDIT: Not to disappoint anyone but keep in mind my 5.0 litre SC engine had a complete pipe, hose and pump failure at 6 years 50k miles and the 3.0 litre SC had the same happen after only 3 years. It’s fantastic these 2 parts are available however that still leaves every other plastic pipe of which there are many. Considering the supercharger must be removed and seals replaced in order to replace these 2 parts it would be highly advisable at that time to replace every other part of the cooling system related to this procedure.

Stuart - If/when you successfully get them installed on your XJR; please post the results here and on the X351 Forums. They will be much appreciated by your fellow owners/Forum members. Thanks, Ralph
Just to corroborate what we already know.... I sent out an inquiry to the vendor, asking if there were any plans to produce this aluminum replacement kit for the non supercharged 5.0 and got a confirmation that there isn't anything available at this time.

they would sell like hot cakes. i hope there is the numbers to make work.
P.S. Don't wait until after your plastic pipes completely break, as catastrophic engine damage can occur. If you notice the tell-tale aroma of anti-freeze, your coolant overflow tank is low or empty, and there's a puddle under your car, get it checked right away. Don't drive it or run the engine if you get a hot engine warning light, and have it towed to your dealer or independent mechanic who is qualified and competent to work on your Jaguar.

Stuart, whilst the supercharger’s off, are you replacing all of the other related hoses and pipes such as the rear crossover, throttle body heater hose (that’s the very long one which goes from the back of the engine to the front of the engine), oil cooler outlet pipe (common fail pipe from the rear of the water pump
to the oil cooler under the supercharger), etc? Might check the supercharger coupler for slack as well.

FYI, If many of the plastic pipes and hoses are being replaced, and the oil cooler outlet pipe is being replaced as well, the water pump with then have to be removed to install the outlet pipe, even if the pump has been updated and is not leaking.

Is the throttle body hose part number C2Z28432? I'm replacing mine as well while replacing all the other plastic pieces. If we are referring to the same part... a section of the throttle body hose is rubber correct?
Yes I believe that’s the one. It’s quite long due to its long path.
I mentioned the oil cooler pipe since it’s quite easy to do at this time. The crossover pipes can’t be done without the supercharger removal and that’s the hardest part. Once it’s out of the way it takes just minutes to R&R all of the pipes.

Yes, but the oil cooler pipe requires the removal of the water pump correct? What if your water pump had already been replaced? I have a one year old 2015 version of the latest water pump. Should I be replacing it anyway in order to replace the oil cooler pipe?

As I write this my XKR is getting all of the plastic tubes replaced. I took it in for its annual major service on Monday. Got a call from my Service writer that the pipe under the supercharger had started leaking through a small fissure on the seam. I decided I didn't want to wait for the aluminum pipes and told them to go ahead and replace everything while they were in there. I am supposed to get the car back on Thursday. I replaced the water pump on this car a little over 3 years ago.
The good news is the new front pipes from JLR are redesigned as seamless one piece and expected to last much longer. The bad news is the rear crossover’s still a 2-piece fused pipe and prone to leaking as mine have. Still replacing it now whilst the supercharger’s removed wont take much effort or cost.
