A/C Refrigerant System Oil Charge Replenishing
WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
If oil was removed from the A/C system during the recovery process or due to component replacement, the same quantity of PAG oil must be replenished. If no oil was removed from the A/C system during recovery, do not charge any PAG oil into the A/C system. Oil can be injected into a charged system using J-45037 A/C Oil Injector. For the proper quantities of oil to add to the A/C refrigerant system, Refer to Approximate Fluid Capacities (R-134a) .
