Dunno. I'd missed the part in the manual where it says that a replacement compressor comes preinstalled with 150ml of oil. 20ml supposedly remains inside after draining. It doesn't say anything about a special procedure. I suspect I should have just added 130ml rather than adding into various places.DetroitAC wrote: ↑Mon May 30, 2022 12:15 pm
They do almost always ship the compressor filled with the required oil amount for the full system. But 1st startup in the assembly plant is usually very special, takes place with the ECM being controlled at end of line tester, and they start the compressor with a sequence that gently, slowly pumps the oil out. I'd never fill one up for servicing.
I had a mild scare as I couldn't get the compressor to start and had visions that I'd damaged the wiring harness when I removed the compressor. Only about 1/5th of the 12oz can had flowed and then it stopped. I'd been running the AC for 30 mins and the compressor would not start. I was tightening the valve on the can tap to seal it when suddenly I heard the refrigerant flowing again, pressure on gauges jumped and the compressor started and the can started to empty. I suspect the valve on the can tap was being goofy.
Anyways, all back together. Wife said it AC on for her test drive was uncomfortably cold so she had to turn it off

Thank you for all the help. I'm not sure I really needed to ask the question as I think the correct procedure was in the service manual all the time but the replies here gave me the confidence.
When the dye kit comes I'll add some. Yes, it would have been a lot easier to just add some dye when I was switching between the two cans of R134a. Oh well, there is always "next time".
I found a TSB for the 13-15 model year to resolve this pressure pipe cracking. The clamp/bracket nearest the condenser gets discarded as it was making the pipe too ridgid. I don't have the bracket on my 16 model year though the clamp is still on the replacement pipe .... I guess the fix didn't entirely stop the cracking issue. Hopefully it won't occur again.
Thanks again!
