Hoping to only replace the black cap on the silver line. Anyone know if it can be done or does the whole thing need to be replaced?

 

It can absolutely be replaced, but not from Jaguar, who will only sell you the part as part of the pipe.

It's the same thread/length as the ones used on a load of BMWs, so you can replace with Dorman Part No 902-404, available at Autozone as well as Amazon etc.

Also, if you check eBay you can find brass aftermarket replacements for around $10 which I think is probably well worth it.

 

This worked like a champ!! Thanks for the tip!

 

No way...I have the same issue (I HOPE), what engine is that? 3.0 S/C? Is that the same pipe (Part Number C2Z11054) or a different one. If this is it....I'm about to donate the remaining $1,765 to charity (I got quotes $1775+TAX for the repair, Jaguar said they can only order the bleeder screw with the pipe + 7 hour labour)

 

Hey, how long did the job take? Did you replace it with a brass plug or a plastic one. Curious to know if the heater hose was damaged in the process.

 

I only replaced the bleeder screw. The screw head snapped off when I was unscrewing it and then I had to get the body of the screw out which took a little while. But in the end, the Dorman Part No 902-404 did the trick. I didn't get the brass screw because I needed a quick replace, but I most likely will order one soon so I never have to worry about it again.
