Refrigerant Oil: Description and Operation
Refrigerant Oil - Description
DESCRIPTION
The refrigerant oil used in R-134a refrigerant systems is a synthetic-based, PolyAlkylene Glycol (PAG), wax-free lubricant. Mineral-based R-12
refrigerant oils are not compatible with PAG oils, and should never be introduced to an R-134a refrigerant system.
There are different PAG oils available, and each contains a different additive package. Use only refrigerant oil of the same type as recommended to
service the refrigerant system (always refer to the specification tag included with the replacement A/C compressor or the A/C Underhood Specification
Label located in the engine compartment).
CAUTION: Be certain to adjust the refrigerant system oil level when replacing an A/C compressor See: Service and Repair/Refrigerant Oil Level
. Failure to properly adjust the refrigerant oil level can prevent the A/C system from operating as designed and can cause serious
A/C compressor damage.
The A/C compressors used in this vehicle are designed to use VC-46 PAG refrigerant oil. Use only this type of refrigerant oil when servicing the A/C
compressor.
