Refrigerant Oil: Description and Operation
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).
The Denso 10S17 A/C compressor used in this vehicle when equipped with the 3.7L, 4.7L or 5.7L engine is designed to use ND-8 PAG refrigerant oil.
Use only this type of refrigerant oil when servicing the A/C compressor for these engines.
The Visteon HS-18 A/C compressor used in this vehicle when equipped with 5.9L or 6.7L diesel engine is designed to use VC-46 PAG refrigerant oil.
Use only this type of refrigerant oil when servicing this A/C compressor.
