2004 Jaguar S-Type. Looking for broken part ( Pictures Provided )

One of the lovely plastic parts from that era. Not surprised it failed. Those are the upper radiator hose and the additional hoses. The part number is XR854920K and it is available through a few sources. You cannot block off the broken part as it has to be there for the system to purge out air and return coolant as it thermally cycles. Plus the hoses are all specifically molded and fused to the part and clamped so that you cannot replace only the plastic. Ford owned them at this point and the S-type was basically the Thunderbird that was redressed to look like a Jaguar. Even used the Ford 3.0 as the base engine. Then Jaguar engineers added different cylinder heads that created cooling problems and this nest of hoses was the result of that. Because of the materials used you can't plastic weld or glue it. There was a company that made one out of aluminum but I haven't seen one out in the wild. If you know a good welder you might get one fabricated but it would be more than buying the new part.

You are welcome. This is one time I don't advise on a used part, I don't know what the cause is but from about 2000 most of the plastic used in vehicles is junk, and of course they used it in the cooling systems. At least in this case you can still get new parts, there are many where you cannot.
