Lubrication Oil
Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
Maintenance of Oil Quantity in Compressor
The oil used to lubricate the compressor circulates through the
system with the refrigerant. Whenever any component of the sys-
tem is replaced or a large amount of gas leakage occurs, add oil
to the compressor to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions
may result:
I
Lack of oil: May lead to a seized compressor
I
Excessive oil: Inadequate cooling (thermal exchange impeded)
Checking and Adjusting
Adjust the oil quantity according to the flowchart shown below.
