INSTALLATION

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system Refrigerant Oil Capacity . Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.

CAUTION: Always use ND-11 Polyester (POE) oil from Mopar(R) in Hybrid Electric Vehicle (HEV) models. Never use Polyalkylene Glycol (PAG) oil in an HEV model. See Refrigerant Oil for more information.

CAUTION: Polyalkylene Glycol (PAG) oil can contaminate the refrigerant system of a Hybrid Electric Vehicle (HEV) and lead to A/C system damage and failure. If the refrigerant recovery/recycling and charging equipment was last used on a non-HEV model, flush the hoses of the equipment with a solvent approved by the equipment manufacturer before using the equipment on an HEV model, or use refrigerant recovery/recycling and charging equipment designated only for HEV models by your service facility. See the operating instructions supplied by the equipment manufacturer for proper use and care of the refrigerant recovery/recycling and charging equipment.

NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system Refrigerant Oil Capacity .

NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.





1. Remove the tape or plugs from the evaporator tube fittings and all of the expansion valve ports.
2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them on the evaporator tube fittings. Use only the specified O-rings as they are made of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
3. Install the A/C expansion valve (2) onto the evaporator tube tapping block (3).
4. Install the two bolts (1) that secure the A/C expansion valve to the evaporator tube tapping block. Tighten the bolts to 11 Nm (97 in. lbs.).






CAUTION: Use care when installing the A/C lines to the A/C expansion valve. Carefully align the tube ends with the valve prior to tightening the A/C line retaining nut or damage to the sealing rings and tube ends may occur.

5. Install the A/C suction line (1) and the A/C liquid line (2) to the A/C expansion valve (3) A/C Suction Line - Installation or A/C Liquid Line - Installation.
6. Install the right front wheelhouse splash shield.
7. Lower the vehicle.

WARNING: Always follow vehicle service procedures to properly connect batteries on an HEV model. Serious or fatal injury may result from improper service procedures.

8. On HEV models, reconnect the battery system using the service disconnect at the battery pack .
9. On gasoline only models, reconnect the negative battery cable.
10. Evacuate the refrigerant system Refrigerant System Evacuate.
11. Adjust the refrigerant oil level Refrigerant Oil Capacity.
12. Charge the refrigerant system Refrigerant System Charge.
