Refrigerant And Refrigerant Oil Capacities

Different capacities for refrigerant R134a and refrigerant oil are designated, depending on refrigerant circuit design (with one or two A/C units / evaporators). and REFRIGERANT OIL (A/C System with Refrigerant R134a; Refrigerant R134a Capacities, Refrigerant Oil and Approved Refrigerant Oil).

The compressor as a replacement part has different refrigerant oil fill capacities, therefore note the exact part number. Refer to the A/C Compressor -G111- (A/C System with Refrigerant R134a; Refrigerant R134a Capacities, Refrigerant Oil and Approved Refrigerant Oil). The reason for the different refrigerant oil capacities in the compressor lies in the design of the compressor itself, note these refrigerant oil capacities. Too much oil in the circuit leads to higher pressures and reduces cooling performance of the system. Too little refrigerant oil may lead to lubrication problems in the compressor.

When charging the A/C system, always use maximum amount of refrigerant R134a, as some of the refrigerant remains in the hose of the refrigerant recovery, recycling and recharging unit.

Refrigerant circuit may only be filled with approved refrigerant oils.

Zexel / Valeo, Sanden and Denso compressors require different refrigerant oils. Refer to A/C Compressor -G111- (A/C System with Refrigerant R134a; Refrigerant R134a Capacities, Refrigerant Oil and Approved Refrigerant Oil).

Use only the specified oil from a sealed container (PAG oil absorbs moisture). Do not use oil if it is contaminated with moisture or if oil container has been left open. Refer to REFRIGERANT OIL (A/C System with Refrigerant R134a; A/C System General Information).
