♦ The replacement compressor contains the full quantity of oil
intended for the refrigerant circuit. On A/C compressor re‐
placement, the quantity of oil in the A/C compressor is there‐
fore to be adjusted. Refer to
⇒ “5 Removal and Installation“, page 191 .
♦ As the A/C compressor and engine always operate at the
same time and the entire quantity of refrigerant oil is contained
in the A/C compressor, the circuit must be completely assem‐
bled before starting the engine. Refer to ⇒ Heating and Air
Conditioning; Rep. Gr. 87 ; Removal and Installation .
♦ These A/C compressors are available as replacement parts
with different oil fill capacities, therefore note capacity on the
