2000 c70 ac compressor oil

MattA · Post by **MattA** » 09 Jul 2014, 07:37

I am in the process of replacing my ac compressor, part# 8708581. My plan was to drain the old compressor of oil to determine how much and which opening to fill. Problem is there was no oil in the old compressor, (maybe the problem). What viscosity oil and how much should I put in and which opening does it go in to. Aside from the two hose ports there is a bolt with a hex screw in the center with a seal and a regular bolt with a seal both next to the hose connections.
Thanks

There are a couple of threads on getting the right PAG oil, and jimmy57 from TX is the expert on AC for Volvo. I believe PAG 11 is the right oil for your 2000, but CONFIRM please.

Whats the make/brand/model compressor you are using?

Oil info from Alldata

BG1 Topping up lubricating oil

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.)

I would use the quantities abscate listed, it is better to have too much oil versus not enough as it will dry out the seals and do damage to the compressor.

There is a caveat to add at least 70 mL to the compressor. Note the discussion on what to do based on the status if your AC system pre-repair.

I believe on these systems all the bulk oil ends up in the accumulator, where it is dispersed through the system. Im on the second summer of repair on my AC (new Evap, new hoses) and it is working like new.

At least in FL you know you will be using it every day!

what disc should I use and which port does it go in. There was no oil in the old compressor to compare.
