REFRIGERANT OIL ADDING
SPECIAL TOOL(S)
Refrigerant Oil Adding
CAUTION: During normal A/C 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 refrigerant 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 for refrigerant oil adding amounts and methods of installation.
Refrigerant Oil Adding for New A/C Compressor Installation
NOTE: Service A/C compressors are shipped without refrigerant oil.
1. Rotate the old A/C compressor shaft 8 to 10 full rotations (clockwise) while collecting the refrigerant oil in a clean measuring cup.
- If the amount of oil drained from the old A/C compressor is between 85-142 ml (3-5 ounces), add the same amount plus the amount collected during refrigerant recovery.
- If the amount of oil drained from the old A/C compressor is greater than 142 ml (5 ounces), add the same amount plus the amount collected during refrigerant recovery.
- If the amount of oil drained from the old A/C compressor is less than 85 ml (3 ounces), add 85 ml (3 ounces) plus the amount collected during refrigerant recovery.
Refrigerant Oil Adding for New Suction Accumulator or Receiver/Drier Installation
1. Drill one half-inch hole in the old suction accumulator or receiver/drier cylinder and drain the oil into a clean measuring cup.
2. Add the quantity of oil drained, plus the amount collected during refrigerant recovery and 60 ml (2 ounces).
Oil Injection Using a Dye/Lubricant Injector
NOTE: If fluorescent leak detection dye is also to be added during A/C charging, the dye may be added to the dye/lubricant injector along with the refrigerant oil.
1. Evacuate the refrigerant system.
2. Assemble the dye/lubricant injector using the correct adapters to match the amount of PAG 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 PAG 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.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
