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 contain a different additive package. Always use only the type of refrigerant oil recommended for the
A/C compressor in the vehicle.
CAUTION: Be certain to adjust the refrigerant system oil level when replacing an A/C compressor. 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 Denso 5SE12C A/C compressor used in this vehicle is designed to use ND-8 PAG refrigerant oil. Use only this type of refrigerant oil in the
refrigerant system.
