What are the technical specs and what comes preinstalled?

The Dilomber CO 22301C ships with the compressor body, QS90 clutch assembly, and factory-measured PAG46 oil. It is prepared for R-134a refrigerant systems and designed to match OE mounting and pulley configurations for the listed vehicles.

What should I know before replacing only the compressor?

Installing a new compressor without addressing the rest of the A/C system risks rapid failure. Contaminants, oil starvation, or blockages left in the system will damage the new unit.

• Flush the entire refrigerant circuit and replace the receiver/drier or accumulator as necessary.
• Check for leaks, replace expansion device or orifice tube if contaminated, and verify proper oil level and refrigerant charge.
• Use proper vacuum and charging procedures to avoid air/moisture contamination.
