Something to mention is that the ac lines should be flushed and the orifice filter changed out. The system should be fully cleaned out before being recharged. This will help prevent premature failure of the new ac compressor.
I generally drain the factory placed pages oil and add 3oz green pag with UVDye never had an issue yet of course if I do I have done the preventative step with the dye to find the leak . Anyway well done on the video definitely flush the system it works
