A/C - Refrigerant and Lubricant Guidelines
SOURCE: KIA Technician Times Volume 7 Issue 5, 2004TITLE: A/C Refrigerant and Lubricant Guidelines
APPLIES TO: ALL
SERVICE TIP:
Insufficient quantity and/or incorrect specification of refrigerant or lubricant used may cause premature failure of A/C compressors. Please use refrigerant and lubricant guidelines shown below when servicing A/C systems.
If the A/C components are replaced, add or remove the following refrigerant oil (PAG) as follows:
Components Being Serviced: Required Amount:
Evacuate and Recharge A/C System Add 30 grams (1 oz)
Evaporator Add 60 grams (2.1 oz)
Condenser Add 50 grams (1.7 oz)
Receiver-drier Add 40 grams (1.4 oz)
Compressor Remove 70 grams (2.3 oz)
Before charging the A/C system, add the same amount of new refrigerant oil to the A/C system that was removed during the recovery, plus additional refrigerant oil required from the table.
CAUTION
^ Kia Service Manuals may not list the PAG number shown in the table, however OEM part number ZXL 200PG is equivalent to PAG 100 and OEM P/N FD46XG is equivalent to PAG 46.
^ NEVER re-use PAG oil, replace with fresh new oil every time. PAG oil absorbs moisture and replacement is always recommended. Use ONLY recommended type and quantity.
^ When all components are replaced due to compressor break-up with excessive debris in the system, there is no need to add additional PAG oil. New compressors are shipped with approximately 7 oz of PAG oil.
^ If the oil in the A/C system is lower than the specified amount, compressor durability will be decreased.
^ If the oil amount in the A/C system is higher than the specified amount, A/C performance will be decreased.
