Ac compressor oil

Some compressors do and some do not. Take out the drain plug and drain the oil into a clean container then replace with the correct amount. Remember to drain the old compressor to see how much oil is left in the system

1 Are you recharging yourself?
2 Have you removed any previously installed components like compressor, condenser etc
In the case you are replacing any of the components you should get the oil from the parts store or it usually comes with a new compressor. I think it is about 120 CC but in case you are just changing the compressor the rule of thumb is to drain the oil out of the old compressor in to a measurable container and replace with the same amount in the new compressor. attached is a chart if any of the components have been changed and how much oil might be needed.

there will be no need to put oil in an ac compressor
new compressors already have oil in them and old units have the oil through out the ac system that comes back in with the gas.

have dealership discharge airconditioning system.you need to disconnect refrigerant lines going to the AC compressor you probably need refrigerant lines disconnect tools to remove disconnect refrigerant lines.you need to remove drive belt.and safely raise support vechicle remove tire or wheel work from under vechicle you have to loosen AC COMPRESSOR bolts then remove AC COMPRESSOR.be sure pour old refrigerant in a measuring cup so you can pour same amount new oil in the new compressor.add couple ounces if old AC COMPRESSOR dry.

Hello: Drain oil out of old compressor, measure amount and put that amount in new compressor. Approximately 8 oz.

The system oil capacity (Total- if all components replaced or flushed) is 10.0 oz. Manufacturer oil proceedure for the compressor alone is to drain and measure oil from the old compressor (make sure to turn shaft a few times to get it all out) and add the same amount of new oil to the new compressor. Chrysler says that you must use a sp15 PAG oil.
Note that you must flush the entire system when replacing the compressor in order for the warranty to be valid on the replacement part. Also require is the replacement of the drier assembly.
Have a great day!

Most the time its 8 oz,, need to check with the seller and see the specs on compressor,it should say on ac compressor

1. Disconnect the negative battery cable.
2. Discharge the refrigerant. (See REFRIGERANT CHARGING.)
3. Remove the splash shield.
4. Remove the A/C drive belt. (See DRIVE BELT REPLACEMENT [LF].)
5. Detach the two wiring harness clamps.
6. Disconnect the magnetic clutch connector.
7. Remove the A/C compressor protector.
8. Disconnect the cooler hose (LO) and cooler hose (HI). Do not allow remaining compressor oil in the refrigerant line to spill. (See Refrigerant Line Removal Note.) (See Refrigerant Line Installation Note.)
Caution • If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise or other malfunction could occur. Always plug open fittings immediately after removing any refrigeration cycle parts. 9. Remove the compressor protector.
10. Remove in the order indicated in the table. Do not allow remaining compressor oil in the A/C compressor to spill.
Caution • If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise or other malfunction could occur. Always plug open fittings immediately after removing any refrigeration cycle parts.


11. Install in the reverse order of removal.
12. Perform the refrigerant system performance test. (See REFRIGERANT SYSTEM PERFORMANCE TEST.)
A/C Compressor Installation Note 1. When replacing the A/C compressor, remove the following amount of compressor oil from the new A/C compressor.
Amount drained (approx. quantity) • 155 ml {155 cc, 5.24 fl oz} - [compressor oil from old A/C compressor + 15 ml {15 cc, 0.5 fl oz}]

You need to also repalce the drier, make sure the compressor has the amount of oil required, vac down the system then charge with proper amount of r134a.

Tip the drier upside down and allow some of the oil trapped in the drier to drip into a small container. Smell the oil. If it smells like fruit then it is an Ester based oil. Look at the label on the compressor as the type of oil used in the compressor should be listed on this label and NEVER use a different type of oil then the one listed as the oils are NOT mixable. The amount of oil is depndent upon the size of the system and the amount the compressor has been initially filled with. Check with the vehicle manufacturer or a local Air Con service centre as they will be able to advise regarding amount. If you add the oil yourself, remember that all the synthetic oils used with modern refrigerants is a health hazard and can cause dematitis and severe skin irritations. Certain types of oils are also known to be carcinogenic so wear gloves and face protection. Remember that too much oil is worse then not enough as overcharging the oil can cause flooding in the condenser and reduces the ability of the condenser to allow the transfer of stored heat out to the surrounding air..
