COMPRESSOR OIL BALANCING
DRAINING PROCEDURE
1. Remove the compressor crankcase oil drain plug and drain the crankcase into a clean, graduated container.
IMPORTANT: Drain and measure as much of the refrigerant oil as possible from the removed compressor.
2. Drain the oil from both the suction and discharge ports of the removed compressor into the same container. Rotate the compressor shaft to assist in draining the compressor.
3. Measure and record the amount of oil drained from the removed compressor. This measurement will be used during installation of the replacement compressor.
4. Properly discard the used refrigerant oil.
BALANCING PROCEDURE
1. The replacement compressor is shipped without refrigerant oil.
IMPORTANT: The refrigerant oil in the A/C system must be balanced during compressor replacement. Follow the balancing instructions provided with the compressor.
2. Calculate the amount of refrigerant oil required for oil balancing. Compare the following refrigerant oil capacities:
- The amount drained and recorded during compressor removal.
- The amount recommended for component replacement.
3. Add the greater amount of refrigerant oil to the A/C compressor.

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.
