Default V12 6.0 cooling

I may be missing something really obvious but can anyone post a photo of the bleed screw for the 6.0?
All I can see above the radiator is what looks like a circular (tubular) plug,
Also am I right in assuming there is no radiator cap on this model? If there is, where the hell is it and if there isn't, where do you fill the system? I can only see the expansion valve cap.
Photos would be helpful.

My car is 1997 DD6 6.0.

Might get more information in the XJS ( X27 ) section as it is the same engine in the X300 body / engine compartment shared components , try to stay in the 1997 range .

There is a search box in the upper right corner on this website .Example :

Is this the bunny ? This pic is from a reported 1994 and the X300 has the similar black cooling expansion tank except more square in the lower section of the pic

G'day 9mm,

According to the service manual the cooling system self bleeds if you run the car with the heater on. The highest point in the system is the filling point.

No bleed screw.
No radiator cap.
Fill at expansion tank.
Who are we to question Jaguars wisdom?

Apparently, they made the XJ81 (V12, XJ40 body style) as a Daimler Double Six for markets outside of the USA. That's cool. Must be rare.
