⚠️ IMPORTANT – COMPRESSOR OIL
PLEASE READ BEFORE INSTALLATION.
The factory ACDelco label on this compressor specifically states:
“SERVICE PART – OIL MUST BE ADDED.”
The installer is responsible for adding the correct type and amount of compressor oil required for the vehicle/application before operation.
DO NOT assume this compressor contains the required amount of operating oil.
GM\'s current specification identifies the compatible lubricant type as PAG oil. The exact amount required should be verified according to the vehicle\'s factory service information and the condition of the remaining A/C system.
Improper lubrication, incorrect refrigerant charge, contamination, or incorrect installation can cause compressor failure.
Professional installation is strongly recommended.
CONDITION

These cosmetic marks do not indicate previous installation.

Please carefully examine all photos. You will receive the exact compressor pictured in this listing.
