Yes, this is easy to replace, I assume all of the refrigerant has leaked out correct? Here is how the job is done and I have included a video to help with the A/C vacuum down and recharge.

The parts in the middle do it just screw out? I tried a 5/8 wrench but my wrench want to slip. This is valve core wrench I'm using trying to remove the core but nothing come out.
