2) On the back side of the water pump, there is a roughly 3 inch/80mm piece that connects the water pump to the oil cooler. There is a metal version of this out there, get it if you can.
3) the elbow going into the water pump at the 4 o'clock position (when standing in front of the car). This piece has been redesigned a number of times to change how the seal removes any water pressure pushing against the bearing, leading to an early failure of the bearing.
4) the small tube coming off the front of the water pump, up to near the intake, running over to the right side. It has a funny Y shaped plastic piece in it that serves no purpose (did back on the original design, but not any more).

Recently I went to my local dealer to get a parts list of cooling system stuff I should replace. I attached a PDF of the list along with exploded views to reference.

Parts listed are below. Wondering if this list is complete enough? Anything missing I should include?

1. AJ813565 HOSE
2. C2Z28467 TUBE
3. IAJ89664 PIPE-OUTLl
4. AJ813909 PUMP-WATEI
5. C2Zl8658 TUBE
6. AJ811539 SEAL
7. lc2D6005 HOSE-ENGH
8. AJ814007 PIPE-HEATE

Your dealer has included the right parts for the water pump! In our experience, replacing the intake manifold gaskets because of the age of the vehicle would be a good idea. Part number AJ811713 which happens to be the same as the Land Rover gaskets part number LR010881-it takes 8 to do this job.

Also I have done a lot of research and have a great relationship with my local Jaguar dealership parts department and can provide you with the land rover part numbers for some of the other parts needed for this job. Hope this helps!

1. AJ813565 -LR092992
   
2. C2Z28467 -LR049989
   
3. AJ89664 -LR018275
   
4. AJ813909 -LR097165
   
5. C2Zl8658 -LR028136
   
6. AJ811539 - LR030593
   
7. AJ814007- LR109402 this part number can also be found as C2Z31645 it was the original part number

But, as part of this, we like to get to know one another. So, please stop by the New Member section and tell us a little bit about yourself and what brought you to your jaguar. This will also give you a chance to meet those that make this place what it is.

As for your question, I would say to first come over to the X351 section (for all XJs 2009-2019). Here you will get all the info you need about your car and lots of helpful information. As for the water pump, I would not worry so much about the water pump, but more with the plastics that are around it. The plastic seems to be what is failing more times than not. There has been a lot of discussion on this very topic in the X351 section and you will find that the water pump complex has been redesigned a number of times. With this being said, is replacing the water pump a good bit of insurance, it sure is. Especially when you figure that a new engine for your car can run up to $45k (ask some of the members about the quotes they got from their dealership after they drove their car hot).

The big things that you want to pay attention to is the small tubing in the near right side of the engine bay (as you are standing in front of the car, looking into the engine bay). This tubing gets brittle with heat cycles and will suddenly crack (especially when working in the area). and there is a plastic transfer tube on the back of the water pump that feeds the engine that will suddenly split, resulting in major water loss. This transfer tube, someone has actually come out and made a metal version of it (info in the X351 section). So, if you do the water pump, spend the little bit extra and get that. Unfortuatnely, for what you are looking to do, you can probably plan on spending about $1500 on the water pump. BUt, like I said, it is good insurance from a major inconvenience.
