NIPPONDENSO 10-Cylinder
To ensure that the Nippondenso 10-cylinder compressor has the proper amount of lubricating oil, discharge the system using approved refrigerant recovery/recycling equipment and remove the compressor. Remove the service valve assembly. Turn the compressor upside down and drain the oil from it. Once the oil has been drained, refill the compressor with 2.0-3.4 oz. of Densooil 6, Suniso No. 5GS or equivalent compressor oil.
