Well, certainly you can turn the bolts the same as an A/C mech.

The thing is, after the original rx-dryer is removed, the system should be
blown with nitrogen to remove as much old oil as possible.

Then after the new o-rings and new rx-dryer is installed, the system should
have first a pressure test for leaks, and then a hard vaccuum pulled to
remove as much water from the system as possible.

At least, that's how it was done on mine, and to me, it makes sense. Why go
through the whole process, just to have the system leak or be contaminated?

How else could you be sure your system was leak-free?
