I have a 2003 XKR and the coolant hose connection on the right rear of the engine is leaking. It is close to the upstream OS sensor. It is a plastic clamp which connect a steel pipe to a rubber hose. How do I release this and also how is it repaired? Do I need to replace it or can I just remove it and put a regular hose clamp in it' place?

Thank you,
Jim Webb

Jim,

That's a quick-release clip made by the Norma company. It will release somehow by pressing the plastic tangs etc.

I'm not exactly sure, from your pic, where that hose is coming to / from. However if you look on the Jaguar parts website for your 2003 XKR, you might well find that the clip is still available.

Good luck

Paul

Thanks Paul:

I have poked around the clips but it doesn't want to release. It is located at the right rear of the engine near the OS sensor. I think it my go to the heater core.

There's a clip to press down that allows the locking ring to slide back. That releases the claw system that grips around the metal pipe. The seal is achieved with an internal O ring. There's often corrosion around the metal pipe making removal awkward.

There's a lot of discussion online about these connectors and the troubles experienced with them. Google Jaguar Norma connectors. Many owners have removed it and successfully used a short piece of heater hose to replace it.

The main purpose for such a quick fit connector would seem to be for speed on the production line, not to make life easy for the maintainer

Jim,

Not sure if it's this pipe, but this may help:

Thank you both for your replies. I will try this again. The link is quite informative Paul. So the next question is: once I get this off can I clean up the pipe and reattach it of do I have to replace the connector? And does that mean replacing the complete hose?

Thank you all for your help!

Jim

Jim,

I THINK that quick-release connector has an O-ring as part of it. If so, I would carefully examine the integrity of that O-ring and change it as necessary.

Good luck

Paul:

Thank you for your comments. I do think that there is an O-ring that may be causing the leak. I'll look into this as soon as I can. I am hoping that I can repair this rather than replace the hose as one end goes under the scuttle and disappears!

I'll let you know what I find.

Jim
