If possible, before checking and adjusting oil level, operate A/C system. If A/C system can be operated properly and/or there are no excessive refrigerant oil leaks, go to next step. If A/C system cannot be operated properly and/or there is an excessive refrigerant oil leak, go to step 3) .
Start engine and operate at 1200 RPM. Turn A/C or AUTO switch on. Set blower motor speed to maximum. If desired, set temperature control so intake air temperature is 77-86°F (25-30°C). Connect manifold gauge set to A/C system. Ensure high-side pressure is 85 psi (6.0 kg/cm² ) or more. If necessary, cover front of condenser to increase pressure, if necessary. Operate A/C system for 10 minutes. Stop engine and go to next step.
Discharge A/C system, using approved refrigerant recovery/recycling equipment. Measure amount of oil recovered during A/C system discharge procedure. Remove compressor from vehicle. Drain, measure, and discard refrigerant oil from old compressor through compressor drain plug. Remove drain plug from replacement compressor and drain oil into a clean container.
Replace compressor oil drain plug and tighten to 13 ft. lbs. (18 N.m). Add refrigerant oil to replacement compressor, through suction port, equal to amount drained from old compressor plus amount recovered during discharge procedure. If any other A/C system components are replaced, add refrigerant oil as specified. See COMPONENT REFRIGERANT OIL CAPACITIES (INFINITI & NISSAN - CALSONIC V6) table.
