Good day if anybody has any tricks for any steps on how to properly remove air pockets from a 2012 Jaguar XF would really appreciate it my having issues

I located the bleeder valve I actually purchased a copper bleeder valve bolt

 

I think the bleed bolts are actually brass. They're a good idea and I got one, but there is a chance it could react over time with the aluminum pipe it screws into - I'm not an expert on these things and I'm sure the risk is pretty small, but I ended up replacing it with an aluminum bleed screw made by ECS tuning here.

In answer to your question, have you followed the bleeding process in the workshop manual? I have the supercharged engine but it's probably the same principle as in the attached pdf

 

Hey bro thank you for responding so quickly I'm actually going to purchase the aluminum when it makes sense thanks for giving me that resource and exactly what I needed was the manual I don't have that thank you for providing that information I appreciate it I'm going to follow up with you on my findings

a light coating of dielectric grease will prevent corrosion of the two different metals.

 

I changed the coolant of my '09 XF with the 4.2 engine, for the second time, about 3 years ago, while we still owned the car. I drained the coolant from the radiator, as you normally would, After that, I refilled the radiator with coolant, except that I installed a special "funnel" made by Lisle Tool Company, their item #24680. This funnel like device, you attach to the fill port of the radiator, and it's held in place with a screw on adapter (it comes with several, so you can use it on different cars). You then start the engine, and let the engine warm up to operating temp, and the radiator will "naturally" bleed off any trapped air.

The advantage of this device, is that it acts as a portable, temporary expansion tank, while the radiator is burping and spitting air and coolant, keeping the mess contained. I also drove the front of my car on a pair of low ramps, to raise it a bit, to help get the trapped air out through gravity. After about 15 minutes of running, the air bled out, I topped off the coolant to the proper level, and that was it.

 

If still having problems consider a vacuum filling device. They are not very expensive and I am looking at getting one as you fill and are done with no bleeding required.
