Greetings member! I am replacing the A/C compressor, accumulator, and orifice tube in my van. According to ProDemand, the total oil capacity of the system is 11 ounces. And the Denso OE replacement compressor comes with 8 ounces of oil in it already. However, the compressor I bought from Advance Auto Parts came with 2 ounces of oil in it. When I removed the old compressor, there was zero oil that drained out of it. Same with the accumulator, which says to drain it out, and add the amount you drained plus 2 ounces. I'm really stuck here, I have no idea how much to add, and I really don't wanna just let it be and install everything. Also, when I run my vacuum pump, will it remove the 2 ounces of oil already in the compressor?
I'd really appreciate your help, as I can't drive the van until I finish this.
Edit, I failed to mention that the old compressor has some sort of sensor on the back of it held in with a snap-ring. The new compressor has a block-off plate held in by a snap-ring, I don't think it will work unless I switch them out. Does anybody have any ideas?
