This high-quality replacement compressor is engineered to meet the fit and function needs of a range of small GM crossovers and compact cars. It arrives prefilled with oil, includes a 6-groove 6PK clutch, and is designed to replace a long list of OE part numbers so technicians and DIYers can quickly verify compatibility.

How should I prepare my A/C system before installing this compressor?

Installing only the compressor is often insufficient; contaminants, low oil, or blockages can quickly damage a new unit. Clean the entire A/C system, evacuate and recover refrigerant, replace the receiver/drier or accumulator, and inspect the expansion device and lines for debris or oil starvation signs.

• Perform full system evacuation and vacuum testing
• Replace drier/accumulator and inspect expansion valve/orifice tube
• Flush lines if contamination or sludge is present
• Confirm appropriate oil charge and leak-free fittings before recharge
