I am flushing and resealing the OEM A/C system on my 65 Coronet and am not having any luck finding a recommendation for what weight PAG oil to use in the old V-twin. Should I use the dip stick to check fill level as in the FSM?
I have found that I should back off the EPR valve adjustment screw 1/4 turn when converting to 134A as well as using 80% of the R-12 fill specs. And ignore the sight glass. Thanks.
