Changed the a/c compressor (Denso 4711325), expansion valve (Rein CRP-ACD0239R), receiver/dryer (99657392901). Filled the system up with BEHR PAO 68 AA1 PAG8 Oil and R134a.

System capacity is 850 grams (30 ounces) of R134a and 195 ml (6.6 ounces) of ND 8 refrigerant oil.

I think I have put 1.6 lbs of R134a in the system and want to top it off closer to the capacity of 1.875 lbs.

Below I have attached the current state of the system performance and want to know if it is okay to just add R134a to the car and if any or all of the data I have collected is valid so far.

Any body else performed the prescribed system performance check and been able to hit the 40 degree mark? My low pressure side seems on the high side already, could this be the compressor doing this since the system is low on refrigerant?

I assume you pulled a vacuum before filling it?

Was going to ask the same thing.

Yes. I pulled vacuum on the system for 1.25 hour. Turned off the pump and monitored it for 1 hour and no change.

Pulled vacuum on it after for another 40 minutes just to make sure all vapors removed.
