Refrigerant Oil Adding
NOTE: During normal A/C (Air Conditioning) operation, oil is circulated through the system with the refrigerant, and a small amount is retained in each component. If certain components of the system are removed, some of the PAG (Polyalkylene Glycol) oil will go with the component. To maintain the original total oil charge, it is necessary to compensate for the oil lost by adding oil to the system with the new part.
1. Refer to the chart below for refrigerant oil adding amounts and methods of installation.
a If an excessive amount of PAG (Polyalkylene Glycol) oil is lost due to a hose rupture/separation or other damage, the total system PAG (Polyalkylene Glycol) oil capacity must be added.
b The amount specified may be used for one or multiple O-ring leak repairs. Do not multiply the PAG (Polyalkylene Glycol) oil amount by the number of O-ring leaks being repaired.
Adding Refrigerant Oil After A/C Compressor Replacement
1. Remove the A/C (Air Conditioning) compressor drain bolt, rotate the old A/C (Air Conditioning) compressor shaft 6 to 8 revolutions while collecting oil in a clean measuring device.
- To install, tighten to 30 Nm (22 lb-ft).
- If the amount of oil drained from the old A/C (Air Conditioning) compressor is less than 89 ml (3.01 fl. oz), remove 118 ml (3.99 fl. oz) from the new A/C (Air Conditioning) compressor.
- If the amount of oil drained from the old A/C (Air Conditioning) compressor is 89 ml (3.01 fl. oz), remove 89 ml (3.01 fl. oz) from the new A/C (Air Conditioning) compressor.
- If the amount of oil drained from the old A/C (Air Conditioning) compressor is 118 ml (3.99 fl. oz), remove 59 ml (1.99 fl. oz) from the new A/C (Air Conditioning) compressor.
- If the amount of oil drained from the old A/C (Air Conditioning) compressor is 148 ml (5 fl. oz), remove 29 ml (0.98 fl. oz) from the new A/C (Air Conditioning) compressor.
- If the amount of oil drained from the old A/C (Air Conditioning) compressor is greater than 148 ml (5 fl. oz), remove 0 ml (0 fl. oz) from the new A/C (Air Conditioning) compressor.
Adding Refrigerant Oil After Multiple Component Replacement After A/C System Contamination
NOTE: This refrigerant oil adding method is to be used when a new A/C (Air Conditioning) compressor, suction accumulator or receiver drier and evaporator core orifice or TXV (Thermostatic Expansion Valve) have been installed due to system contamination and the A/C (Air Conditioning) system has been flushed.
1. If the new A/C (Air Conditioning) compressor is shipped with a new clutch and pulley already installed, remove the A/C (Air Conditioning) compressor drain bolt, shipping caps and rotate the new A/C (Air Conditioning) compressor shaft 6 to 8 revolutions while collecting the oil in a clean measuring cup.
- To install, tighten to 30 Nm (22 lb-ft).
2. Add 60 ml (2.03 fl. oz) directly to the new A/C (Air Conditioning) compressor suction port.
3. Inject the total vehicle PAG (Polyalkylene Glycol) oil capacity minus 60 ml (2.03 fl. oz) to the low-side service port during system charging. For the total PAG (Polyalkylene Glycol) oil capacity specification, REFER to Material(s) .
Oil Injection Using a Dye/Lubricant Injector
NOTE: If fluorescent leak detection dye is also to be added during A/C (Air Conditioning) charging, the dye may be added to the dye/lubricant injector, from the R-134a Loop/Add On Injector Kit-Set, along with the PAG (Polyalkylene Glycol) oil.
1. Evacuate the refrigerant system. REFER to Air Conditioning (AC) System Recovery, Evacuation and Charging .
2. Assemble the dye/lubricant injector and the correct adapters from 219-00069 to match the amount of refrigerant compressor oil to be injected.
3. Verify that all the valves on the dye/lubricant injector are closed.
4. Fill the dye/lubricant injector with the correct amount of clean, new PAG (Polyalkylene Glycol) oil.
5. Install the dye/lubricant injector between the low-side service gauge port valve and the refrigerant service station or manifold gauge set.
6. Open all valves and charge the refrigerant system. REFER to Air Conditioning (AC) System Recovery, Evacuation and Charging .
