Will this compressor fit my Jeep Liberty or Dodge Nitro?

Yes — this compressor is manufactured to match the application points for 2006–2008 Jeep Liberty 3.7L and 2007–2008 Dodge Nitro 3.7L models. It aligns with the same mounting holes, clutch connector, and pulley configuration used on those factory units. Always compare your old compressor’s specifications to confirm compatibility.

• Replaces: CO 10900C and a long list of OEM reference numbers
• Pulley: 6 grooves, 131 mm diameter — matches factory belt routing

What are the technical specs I should know before installation?

The compressor follows HS18 sizing and electrical standards with a 12‑volt clutch circuit. It is prefilled with PAG46 oil at roughly 180 ml to ease installation, but the system should be checked for the correct refrigerant volume during service. Suction port and connection sizes match common factory fittings for these models.

How should I prepare the vehicle and system before installing this compressor?

Proper preparation prevents premature failure. The entire A/C system must be flushed and free of contaminants; replace the receiver/drier or accumulator and expansion device if advised. Allow any cleaning solvents to evaporate completely before fitting the new compressor to avoid contamination or damage.

• Disassemble and clean the A/C system prior to installation
• Confirm condenser and other components are functioning correctly
• Only install after cleaning agents have fully evaporated

What performance or operational differences can I expect?

This replacement unit is designed for steady, quiet operation and to reduce load on the engine compared with worn compressors. At cruise speeds it draws less power, which can help fuel economy and maintain smoother operation of the climate system. Noise levels are engineered to remain low under normal driving conditions.

• Energy‑saving design reduces parasitic load under lower torque conditions
• Low-noise operation for a more comfortable cabin
• Built to match factory performance when installed correctly
