Fluid Type Specifications

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. The Visteon HS15 compressor used in this vehicle is designed to use a PAG refrigerant oil. Use only refrigerant oil of this same type to service the refrigerant system ( always refer to the specification tag included with the replacement compressor or the under hood specification tag).
