Refrigerant Oil - Description






DESCRIPTION

The refrigerant oil used in R-134a refrigerant systems is a synthetic-based, poly alkylene 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 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 is designed to use ND-8 PAG refrigerant oil. Use only this type of refrigerant oil in the refrigerant system.
