part 1: Explaining a little about what was needed to change the ac compressor in a 2016 Cadillac ATS 2.0T . I did the work without videoing it, but I'm going to make a second video after I order the new parts.
I need a new ac condenser and then a shop to add refrigerant, and it will be finished.
in the 1990s, the condensers became a parallel flow design. according to manufacturers, they can not be flushed and need to be replaced when the compressor fails. I'm choosing to replace mine after I saw the amount of metal in the refrigerant oil. You can do whatever you like.
I opened the old compressor and it was destroyed. metal pieces that were stuck in the pistons caused deep scratches and wedged a few pistons tight. I added some pics of the old compressor.
I can try answering questions if you're going to attempt this repair.
