Default 03 XJR-How to remove the coolant crossover pipe

Master Tech. I'm in the process of removing the upper supercharger pulley but don't know how to remove the coolant crossover pipe. What are the steps for removing the coolant crossover pipe on my XJR?

You might be able to point out the part on the diagram that you are trying to remove.

It is the pipe that goes across the supercharger snout. How many hoses do I need to connect and how many bolts do I need to remove.

Hi
Update: I created a new thread for the Supercharger Removal and Install.
I thought maybe other forum members might need it in the future and putting it in a separate thread will make it easier to find later.
https://www.jaguarforums.com/forum/j...f-files-58889/

The components between the reference pointers 6 (Supercharger unit) and 7 (Supercharger pulley) is Coolant Outlet Assembly per JTIS that includes the Coolant Outlet Duct and Termostat Cover -

the JPEC calls the assembly - the Outlet Pipe also lists the components as the Thermostat housing (Part# AJ83968 or AJ81981 depend on engine number) and Thermostat cover (Part# NCC2245BC).

Here is two diagrams of the same assembly I copied into this JPEG file from the JTIS and JEPC (you may want to use the browser zoom level up to 150% to view this JPEG):

Do you want the instructions just to remove the Coolant Outler Assembly or the entire Supercharger?

Hi Vipa
The Coolant Outlet Assembly consist of 2 parts - the Thermostat Housing Cover and the Coolant Outlet Pipe.

Here is the PDF on the Thermostat Housing Cover showing parts diagram:

And the PDF of the Coolant Outlet Pipe - removal/install instructions with illustrations:
