So I sprung a leak in my new 2005 Jaguar XJR in the lower heater core return feed hose and just replaced it. now the upper heater core feed hose is leaking at the connection point to the metal heater core pipe.

So two questions. Is there an o-ring in that that could be bad? (easy fix i'm hoping) if not, i need help finding the part number for it so i can find a replacement hose and connector.




It's the upper hose of number 4 on the above diagram. My diagram doesn't give any part numbers

Thanks for the help!

 

NOTE: it was NOT leaking before i replaced the lower house. However, i did pull the pin and disconnect it in order to the the lower hose disconnected and out. So i'm thinking there may have been an o-ring that fell out when i did this that i just didn't see. I'm hoping so anyway.

Thanks!

 

I was just looking at this as I have a leak in the upper hose #4.

To answer your question there is a rubber ring that fits inside a groove inside the norma connector. Thats the connector held in place by a metal clip.

Did you ever get a part #? It is actually Heater Pipe to Thermo Housing , XJR-JA-C2C-1984 from XKs Unlimited.
