Oil in the A/C system, specification

WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.

Model	Engine	Model Year	Oil, AC compressor R134a
S40 (-04)/V40	All gasoline except B4184SM/SJ(GDI)	All	1161 627-3
S40 (-04)/V40	B4184SM/SJ(GDI)	All	1161 628-1

Corrective actions in the event of slow leakage (longer than 24 hours)

There is not normally a risk of oil loss in event of slow leakage. The following procedures apply when replacing components:

Compressor, replacing

Drain off and measure the amount of oil drained from the compressor. Drain the oil from the new compressor and fill it with exactly the same amount of oil as drained from the original compressor (always at least 70 cm³ ).

Other components, replacing

Drain the oil. Make a note of the volume. Fill up the new components with the same amount of oil.

Corrective actions in event of a fast leak (hose rupture for example)

A fast leak often means that oil escapes with the refrigerant.

When replacing components, the following oil volumes apply to the relevant components.

Component		Gasoline, not B4184SM	B4184SM	Diesel
Compressor	cm³	180	120	135
Evaporator	cm³	60	60	60
Receiver	cm³	20	20	20
Condenser	cm³	15	15	15
Hose	cm³	10	10	10

If the system has been completely drained, or flushed out, and it is completely drained of oil the compressor must be filled with 135 cm³ oil. The remaining 200 cm³ of oil should be poured into the receiver.

NOTE:

Always read diagnostic trouble codes (DTCs)
