Refrigerant Oil - Description
Gas Models
GAS MODELS
The refrigerant oil used in the R-134a refrigerant system on models equipped with 3.7L, 4.7L and 5.7L gasoline engine, 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. Each PAG oil contains a different additive package. A/C compressors in 3.7L, 4.7L and 5.7L gas engine models
are designed to use ND-8 refrigerant oil. Use only this type of refrigerant oil.
HEV Models
HEV MODELS
CAUTION: Polyalkylene Glycol (PAG) oil can contaminate the refrigerant system of a Hybrid Electric Vehicle (HEV) and lead to A/C system
damage and failure. If the refrigerant recovery/recycling and charging equipment was last used on a non-HEV model, flush the
hoses of the equipment with a solvent approved by the equipment manufacturer before using the equipment on an HEV model, or
use refrigerant recovery/recycling and charging equipment designated only for HEV models by your service facility. See the
operating instructions supplied by the equipment manufacturer for proper use and care of the refrigerant recovery/recycling and
charging equipment.
The refrigerant oil used in the R-134a refrigerant system on HEV models is a synthetic Polyester (POE) oil. Never use mineral based R-12 refrigerant
oils or synthetic based PAG oils in HEV refrigerant system.
There are different POE oil types and grades. Always use ND-11 POE refrigerant oil 68043289AA from Mopar(R) in an HEV model. Use of an
incorrect refrigerant oil may create a compatibility problem and lead to A/C system failure.
