If possible, before checking and adjusting oil level, operate A/C system. If A/C system can be operated properly and 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. Turn recirculation switch off. Set blower motor speed to maximum. If desired, set temperature control so intake air temperature is 77-86°F (25-30°C). 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. Drain shipping oil from replacement compressor into a separate, clean container.
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 new refrigerant oil to system as specified. See COMPONENT REFRIGERANT OIL CAPACITIES (NISSAN - FORD FS-10 10-CYL.) table.

⁽¹⁾	If accumulator and compressor are being replaced at the same time, add additional specified amount of refrigerant oil to compressor. If only accumulator is being replaced, add specified amount of refrigerant oil to accumulator.

⁽²⁾	Ensure replacement compressor contains refrigerant oil equal to amount drained from old compressor, plus amount recovered during discharge procedure.

⁽³⁾	Slowly add specified amount of refrigerant oil to low-pressure side of component.

⁽⁴⁾	Add only if a large refrigerant oil leak is indicated.
