Hi I have been noticing a coolant smell from my new to me jag and I think it's coming from this :

Where might I source this and what is it called ??

Thanks!!!

 

I believe that is the first one I replaced on mine, along with the thermostat housing. That's a Norma connector, if you go on eBay, type in 2001 Jaguar cooling lines or something like that and you'll see lots of posts with detail diagrams. Just rummage through them until you come to the one that matches that. Don't try to replace the connector on those, they are plastic and with age...brittle and will crack.
Here's a link for you to keep on hand for review...JagRepair.com - Jaguar Repair Information Resource

 

Thanks a bunch!
