Note
♦ The replacement A/C 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, Denso A/C compressors 6 SEU 14
were installed; these A/C compressor do not have an A/C
clutch (driven by the engine). Compressors from other manu‐
facturers may also be installed at a later time, depending on
the engine. Refer to the Electronic Parts Catalog and ⇒ Heat‐
ing and Air Conditioning; Rep. Gr. 87 ; Description and Op‐
eration .
♦ As of MY 2008, on certain engines, Sanden A/C compressors
(type PXE16) were installed; they do not have an A/C clutch
(it is driven by the engine). Refer to the Electronic Parts Cat‐
alog and to ⇒ Heating and Air Conditioning; Rep. Gr. 87 ;
Description and Operation .
♦ 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 and Air Conditioning; Rep. Gr. 87 ; Removal and In‐
stallation 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.
