Well, the A/C on my '95 (R134a) slowly started working less and less, and so I have a leak. My plan is to replace all the O-rings and the dryer. And while I have it open, I'll pull our the evap unit, clean the fins and such, and replace the expansion valve.
So here's my question: I don't plan on flushing the system out. How much PAG oil do I need to add back into the system? And am I forgetting anything? TIA.
