Note
♦ 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 .
♦ At the start of production, the A/C compressors manufactured
by Denso (type 6 SEU 14) were installed. A/C compressors
from other manufacturers or another type may also be instal‐
led at a later time. Refer to the Electronic Parts Catalog and
⇒ Heating, Ventilation and Air Conditioning; Rep. Gr. 87 ;
Description and Operation (vehicle-specific repair manual).
♦ These A/C compressors are available as replacement parts
with different oil fill capacities, therefore note capacity on the
A/C compressor and the exact part number. Refer to the ⇒
Heating, Ventilation and Air Conditioning; Rep. Gr. 87 ; Re‐
moval and Installation (vehicle-specific repair manual) and
Electronic Parts Catalog.
♦ The reason for the different oil capacities inside the A/C com‐
pressor is due to the design of the A/C compressor (with or
with an oil separator on the high pressure connection) or to the
design of the refrigerant circuit if the A/C compressors are
have the identical design. Pay attention to the different ca‐
pacities. Too much oil in the circuit leads to higher pressures
and reduces cooling performance of the system. Too little oil
may lead to lubrication problems in the compressor.
♦ A data plate may be attached to the A/C compressor by the
manufacturer, indicating the part number and refrigerant oil
quantity.
