How much oil goes in a gen2 AC system.
Im draining the compressors old oil flushing condenser & evaporator while replacing discharge / suction & orface line.

 

Grab the service manual for your truck from here. That info will be in there.

 

It gives amounts for replacement, but I’m don’t know how much remains in the condenser and evaporator after flushing

 

If you've flushed those two components well, there shouldn't be anything left in them, so the replacement figures should be adequate. In my experience with A/C systems, slightly more oil in the overall system shouldn't cause an issue..

 

Replace the drier too, Drier and compressor is where most of your system oil retains.
