1 more question, PAG oil

Postby Lee in Mountain View [OP] » August 11th 2020, 11:48pm

I’m sure having the correct amount of pag oil in the system is paramount to good A/C system performance. So, would it be safer to have a little more oil or a little less in your system? I’m asking because I really would have no idea how much oil would be remaining in my system after replacing the compressor and the accumulator/dryer. My FSM tells me the total required. I know how much is in the new compressor, and my manual tells me to add some to the accumulator. Not knowing for sure how much remains in my system, how much additional I add to reach the full amount required is just a guess. Any thoughts?

Thanks..........Lee in Mountain View

When you remove the compressor, you carefully pour the oil into something you can measure, like a kitchen measuring cup. Then you carefully pour that amount of fresh oil into the new compressor. Do the same with the receiver/dryer.

Like Bob said, a little more is much better than any amount less.
