AC Compressor Oil replacement type and quantity?

[mjc457]

Hello,

I am replacing the AC compressor on a 2014 chevy sonic 1.8L LS because the ac stopped working and the compressor clutch still runs but the gauge readings were high on the low side and low on the high side. The sticker under the hood specifies the type and amount of refrigerant but not specifically the type and amount of compressor oil, just PAG, not PAG 40, 100, etc (see attached photo) I have a service manual that says PAG OIL ISU 105 (see second attached), but I have never heard of this viscosity of PAG and dont see it for sale at any autoparts stores. Does anyone know what and how much to use ? thanks.

Well after looking online, through the service manual, calling the parts department at the dealer, and being transferred to the dealer, I was told he didnt know the viscosity, just knows its PAG oil like the sticker says under the hood. He also told me it is shipped with oil, I asked if he was sure that the oil shipped is the right compressor oil and he said yes. I looked on a tag that came with the new 4 seasons/everco ac compressor from autozone for my car and it said that the compressor may be shipped with shipping oil and it should be drained and the correct type put in, so I called up Everco technical assistance and finally was told:

PAG 46 - 3.7Oz

Even though I did not get an answer on here , I hope this helps someone else doing the job, I am trying to do everything by the books with this job since I have heard of these failing often and my girlfriends failed at less than 30k.
