02 c70 conv. Compressor oil

Post by Gmac69 »

Blew one of the ac lines on my c70. Lost all refrigerant (blew out at all once). Replaced the hose and was going pull a vacuum and refill. Question is, do I need to add compressor oil. Was thinking that some or all blew out.

I would put 100 mL into the receiver, but jimmy is the real guru on this. The P2 compressors have some funny stuff going on turning on early to make sure they don't lock up on oil

Ill try to find his earlier comments on this.

Oh crap, the 2002 C70 is still P80 platform isnt it?

Correct, no high side port.

100 mL in the receiver drier would be my replacement -standby...

Total system capacity is 200ml

You always put at least 70 mL into the compressor

The system should be flushed with 200g R134A if open for more than 24 hours

You need a new receiver drier, too.
The oil must be topped up when repairing a leak or when replacing a component. The quantity required for the component in question will depend on whether leakage has taken place slowly or quickly.

Slow leakage (longer than 24 hours)
Normally with a slow leak there is little risk of oil loss. When installing new components the following procedures apply:
When replacing compressor: Drain and carefully measure the quantity of oil in the original condenser. 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 cubic cm (0.074 US qt.) ).
When replacing other components: Drain oil and measure quantity. Fill new component with same quantity of oil.
Rapid leakage (e.g. hose rupture)
Rapid leakage often means that lubricating oil escapes with the refrigerant.

When replacing component the oil quantities below apply to the new components:
Receiver/Drier 90 cubic cm
(0.095 US qt.)
Evaporator 50 cubic cm
(0.053 US qt.)
Compressor 200 cubic cm
(0.211 US qt.)
Condenser 20 cubic cm
(0.021 US qt.)
Hose 20 cubic cm
(0.021 US qt.)
