Description
Part Description
This A/C air compressor was removed from a 2011 Chrysler Town & Country equipped with the 3.6L V6 engine. The compressor is specifically for the rear A/C system and has been thoroughly inspected by our technicians. It is currently on the shelf and ready for immediate shipment to get your vehicle’s air conditioning system back to full operation.
The A/C compressor is the heart of your vehicle’s air conditioning system, pressurizing and circulating refrigerant through the system to provide cool air. Common reasons for replacement include internal bearing failure, clutch problems, refrigerant leaks from worn seals, or electrical issues with the compressor clutch. When the rear A/C compressor fails, passengers in the back seats lose cooling, making hot weather travel uncomfortable.

Frequently Asked Questions
Will this A/C compressor fit my 2012 Dodge Grand Caravan?
Yes, this compressor fits 2008-2020 Dodge Grand Caravan models with the 3.6L V6 engine and rear A/C system. The interchange number 734 confirms compatibility across these model years.
Do I need to replace other A/C components when installing this compressor?
It’s recommended to replace the receiver/drier and expansion valve when installing a replacement compressor. You should also flush the A/C system to remove any contamination from the failed compressor.
Is this compressor for the front or rear A/C system?
This is specifically the rear A/C compressor for vehicles equipped with dual-zone climate control. It provides cooling for the rear passenger area separate from the main front A/C system.
What causes A/C compressors to fail in these vehicles?
Common failure modes include internal bearing wear, refrigerant leaks from worn seals, clutch problems, and electrical issues. High mileage and lack of regular A/C system maintenance can accelerate compressor wear.
How much refrigerant oil should I add with this compressor?
Consult your vehicle’s service manual for the exact oil specification and quantity. Typically, you’ll need to add the appropriate amount of PAG oil to match what was removed with the old compressor.
Can I install this A/C compressor myself?
A/C compressor replacement requires recovering and recharging the refrigerant system, which needs specialized equipment and EPA certification. Professional installation is recommended for proper system operation and warranty coverage.
