2. If reinstalling the OLD A/C compressor perform the following:
Drain, measure and record the amount of PAG oil from both the suction and discharge ports and the crankcase in the A/C compressor.
If the measured amount of PAG oil drained is less than 60 ml (2 oz), add 60 ml (2 oz) of new, clean PAG oil to the compressor.
If the measured amount of PAG oil drained is greater than 60 ml (2 oz), add the same amount of new, clean PAG oil to the A/C compressor.

NOTE: Refer to Fastener Notice in Service Precautions.
