Well, looks like our 2013 XJ is getting close to that deadly 50k mark when lots of folks experience coolant pipe failures. So, my question is how tough is it for the OLD GUY here to do it at home ? Have the tools, maybe not enough skin on the arms to loose but don't want a blown engine down the road. Looked on Youtube and found a XF that someone did, he had removed the top end Turbo charger and pulled off the pipe and replaced it. I found replacement ones in METAL instead of the infamous failing PLASTIC Crap from Jaguar on Ebay for about $60.00 which seems reasonable. Just need to know if I should undertake it or not, the car is NOT a daily driver. Your comments are welcome.....

Jag coolant pipe

 

Not a very hard job take pictures of where all your brackets are and hose placement other than that the pins that hold the supercharger down can be a little stuck, I found wiggling front to rear loosened it enough to get it off. I changed rear crossover pipe when I took it off as well as the water pump and pipe that I also got a metal on for on Ebay that goes into the oil cooler.

 

Check the oil level in the supercharger and condition of the snout coupler whilst the unit is removed from the engine.

 

And how might that be done????

 

Ian, do you remember what the part looked like or who you might of bought it from on Ebay??? The one that I am looking at getting has the front and rear pipes. so I guess I would want the other one that goes to the oil cooler also if it is all apart....

RKX Upgraded Metal Coolant Outlet Pipes For Jaguar

 

Many, many threads with pictures on this repair. Easy to find with searches. I found and posted these Aluminum parts when they were first released last year? This forum is WAY ahead of anything on YouTube!

New Aluminum Parts!

Remember all 5.0L engines regardless of what model they are installed in are all the same. So an F-Type, XJ, XK, all take the same parts. As posted above most people remove the SC (we don't have a turbo?) to do this repair. It is a great time to replace other stuff like the water pump and SC snout and SC oil

Consider getting the kit like Ian posted above as there are several more things to replace while it's all apart. Note the Aluminum water transfer tube that goes from the water pump to the oil cooler brick. Plus the nice brass nipple that again replaced crappy plastic factory junk.

One thing I would add is to replace the rear water manifold. Even though it's still plastic, it is a known failure point and not too expensive to add to your list.
Up to you too but if I was doing all this work I would also throw a new serpentine belt on. It has to removed to do the repair so zero extra work to replace it.

Also the coolant has a 10 year life and your car is ten this year. You need to drain the coolant to do this repair so again a good time to refresh the coolant. Others might even throw in a new thermostat.

Any remotely sensible person would love and appreciate that post - Thank you !!

 

I wish this were true, but not really.
The aluminum parts only fit the supercharged 5.0L engines.
I know this because they are not available for my wife's Naturally Aspirated (NA) 5.0L AJ133.
There are many 5.0L XJs (and others) that are not supercharged.

And although I looked and may have missed it, I don't see where Ken Dreger described just which engine is in his 2013 XJ. Couldn't it be supercharged, but a 3.5L?

 

Remove the supercharger snout, which is item 8 in the image.

 

He has an X351 fitted with the AJ126, which is a 3.0 litre unit.

The aluminium cooling system pipes fit both the AJ133 and AJ126 supercharged engines.

 

Sorry and very good point on the Aluminum pipes I forgot to add! They are for the 3.0L and 5.0L SC engines ONLY. The NA 5.0L guys are still waiting BUT the vendor has posted that those plus the rear water manifold are under consideration for release in Aluminum. Nothing released yet?

Hi,
Could a forum member please direct me to a anyone selling the upgraded alloy coolant pipe kits for a NA V8? From reading this thread it sounds like the kits are just for the SC V8 and that's what I seem to be finding in my search. Given this thread is two years old I thought perhaps there might have been progress on getting a kit out for the NA V8?

Thanks

 

marke not so far as I have seen unfortunately. Apparently there is not enough demand to make that happen.
Now there are a few parts out there.
Here is a nice kit with what I think are all the metal cooling parts for the 5.0L NA engines and it does include the brass bleeder screw.
5.0L NA Metal Cooling Parts

Note I have not used them and do not have a recommendation either for or against. But take a look so you know what is out there and there are a number of suppliers on EBay and other places.

We did get a message from Euro-Parts that they were looking into it but I have seen nothing yet.
Might be worth your time to send them an inquiry?

Just put on a new OEM plastic crossover and switch to Evans waterless coolant so there is no longer any pressure built up in your cooling system . You'll never have a failure after those 2 changes.

 

Not nearly as hard as I thought. I had to do them in my 2016 this winter.
So glad I found this forum. It helped me a bunch!
The only plastic I have left is that thermostat body, and I'll be replacing that with aluminum soon.

 

Help videos they are old but will help

 

Very helpful. I watched these when I was doing my aluminum pipes.
