Doing the big plastic replacement!

Yes, that gets replaced with the parts above. I replaced the water pump too, so it's all new. I didn't want to leave any of the original plastic in there because it all turns brittle.
I am still enjoying worry-free driving of my XF's while watching all the blow engine threads from cooling system plastic failures.
For those that are just replacing the pieces that are breaking, you're going to find out the hard way that the others will break and you could lose your engine which equals losing your car considering the cost of an engine replacement will likely cost more than another XF.

What would you estimate it costs in total in parts to do all this? And how many hours of labour? I could imagine this would be a great service for an Indy to offer (honestly maybe even a dealer if total labour hours not too crazy). Mine has been perfect but given age (2010) I would pay a reasonable amount to get the whole lot done...

I think it was about $1500 in parts, including the water pump. I went with all OEM Jag parts from discount suppliers like parts.com, ebay, and some dealer items. It would have been much more if I just walked up to the counter at the Jag dealer for everything.
My hours included cleaning the intake valves, which eats a lot of time. I did it over 2 days per XF, and it was somewhere between 10-15 hours total of pretty hard labor for each car.
Not a cheap job when done right. If I were taking it to a mechanic, I would be worried that they would skip steps on purpose to speed things up but still charge you. It's nearly impossible to see the rear crossover pipe without dismantling a lot of parts, and it's a real pain to do, so how are you going to know if they really replaced it? Or if they really bothered to clean the intake valves? It would take almost as much work to check their work than it would be to do the work yourself.
And you would be hard pressed to pin anything on them down the road if something fails that they didn't change. Mechanics can really increase their profits by cutting corners that customers can't check. I would set up inspection points along the process (examine the rear crossover off the car, examine the valves cleaned before reassembling engine, etc.)

Great job. I have the 2011 XJL 5.0 Non SC and I have heard this particular outlet pipe behind the engine breaches and leaks and notorius on these cars and low and behold I think I am having that problem losing a little coolant now as nothing is leaking from up front. Would you happen to know if this is the same exact procedure and setup is the same as my XJL. Hopefully all I have to do is remove the upper manifold and replace that pipe part myself in the back.. NO WAY taking it to the dealership..

Yes I hear water pumps are known for going out frequently on the XJL's but no leaks at the front of engine where the pump is and I cant see any leaks anywhere else so I'm assuming its the back pipes behind the engine, 4 people have brought this up so until I do more research I'm thinking that's what it is, besides I always smell coolant when i get out of the car

The rear crossover is just as much a liability as the front crossover pipe. A lot of people think if they replace the front crossover pipe, they are good to go. But the reality is there's a lot of other plastic to fail, and once one piece goes, you should know that others could go soon. That's why it's better to just do them all, and while you're doing them, take that opportunity to switch to waterless coolant to eliminate the pressure in the system that puts stress on the plastic and the seals for the water pump.

I will be posting up what it takes to replace all the plastic in the cooling system on an XF. I am starting on my Gray 2011 XF, but I plan to do the same with my White XF.
Let's just say, this job could break the spirit of the most die-hard DIYer!
Replacing the heater crossover behind the engine was not easy, but if the front crossover fails, it's just a matter of more time before the rear one fails, so for me it had to be done.
And now I am seeing the effects of direct injection on dirty intake valves, so that will add another evening of work to the project at a minimum!

I ended up getting it without taking off the wiper and cowls. I could not for the life of me figure out how to get them apart. It was a TERRIBLE job without the access that the cowls would have afforded. haha

Would you know the part number of name of these 2 components on a Jaguar XF 2012. I need to replace these according to my mechanic. Thanks

It took a lot longer than I thought it would for me to get around doing my second XF. I am about 70% done after doing some on Saturday and a lot on Sunday.
I almost forgot what a pain in the *ss this job is! That rear cross over pipe is true torture, and that is if you have the right tools for the job!
I bought a little 1/4" ratchet that turns when you spin the handle and that helped a lot, but still wasn't fun.
I have 2 of the 8 intakes cleaned. Some aren't as bad as the others which is interesting considering they are all breathing the same air and no fuel.
After I clean the valves, I just need to put everything together, which is quick.
It is very nice knowing the plastic is all fresh and new water pump, pulleys, and belt. Will be good to go for another 5 years, and I am sure I will have sold them by then.

Using 1/4 inch ratchet with spinning handle is the key Thanks

What was the ratchet that you used
