Hello all,
I’ve been looking for a diagram of all the hoses and pipes for the cooling system. Have a small leak in a hose and not sure which part it is. It’s push to fit part close to the water pump.
thank you in advance.

 

Your current hose that connects to the front of the water pump is part number C2Z28467. You will also need AJ813565 that connects to the heater manifold. While you are in there, the best route is to replace as many plastic parts as possible, as they eventually get brittle and fail. The front crossover has a high failure rate ( AJ89664,) along with the thermostat housing , and rear crossover (which requires the most effort). there are a number of threads on this topic requiring removal of the intake. Just change every plastic part while in there. Good luck.

 

Thank you so much for the help and the part numbers.
I'd like to change all the plastic parts, would you know where I can get either a diagram or all the part numbers. I've been looking here but can't find it.
Also, any recommendations of where to buy good quality parts?
Thank you.

Only OEM Jaguar parts. You can go online and find a Jaguar dealer that discounts and then bring the prices to your local dealer so that he can match them. All the parts needed, excluding the water pump is approximately $800. There are approximately 8 parts required for most of the cooling system excluding the water pump. Make sure you use Jaguar Coolant. The job will require 8 intake manifold gaskets as well.

 

There was a thread here where someone posted the parts they replaced on a 5.0, but I don’t recall if that was an XK or XKR.

 

My usual 'go to' for this type of question is JEPC (Jaguar Electronic Parts Catalogue) but it's not particularly helpful regarding the locations of the cooling hoses and other relevant components. The Workshop Manual gives a better illustration of what goes where:




I've included both 5.0 N/A and S/C versions for comparison.

The Workshop Manuals are available for (free) download in the 'stickies' at the top of the threads.
