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.

NOTE: The A/C liquid line is serviced in two sections. The front section connects between the A/C condenser and the receiver/drier. The rear section connects between the receiver/drier and the A/C expansion valve. On models equipped with the rear heating-A/C system, the rear section of the A/C liquid line also includes an extension tube that connects the liquid line to the underbody lines.

FRONT SECTION





1. Position the front section of the A/C liquid line (2) into the engine compartment.
2. Remove the tape or plugs from the liquid line fitting and the condenser port.
3. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it and a new gasket onto the liquid line fitting. Use only the specified O-ring as it is 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.
4. Connect the A/C liquid line to the A/C condenser (3).
5. Install the nut (1) that secures the A/C liquid line to the A/C condenser. Tighten the nut to 22 Nm (16 ft. lbs.).





6. Remove the tape or plugs from the liquid line fitting and the receiver/drier (3).
7. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it onto the liquid line fitting. Use only the specified O-ring as it is 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.
8. Connect the front section of the A/C liquid line (2) to the receiver/drier.
9. Install the bolt (1) that secures the front section of the A/C liquid line to the receiver/drier. Tighten the bolt to 13.5 Nm (120 in. lbs.).





10. Install the air cleaner housing and resonator (1) Air Cleaner Body - Installation.

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

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

REAR SECTION





1. Position the rear section of the A/C liquid line into the engine compartment.
2. Install the A/C suction line (2) into the liquid line tapping block (4).
3. Install the plastic retainer (1) that secures the A/C suction line to the liquid line tapping block.
4. Remove the tape or plugs from the suction and liquid line fittings and the A/C expansion valve (5).
5. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and a new gasket onto the A/C expansion valve. 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.
6. Connect the A/C suction line and the rear section of the A/C liquid line to the A/C expansion valve.
7. Install the nut (3) that secures the refrigerant line tapping block to the A/C expansion valve. Tighten the nut to 23 Nm (17 ft. lbs.).
8. On models equipped with the rear heating-A/C system, connect the underbody liquid line to the liquid line tapping block A/C Liquid Line - Installation or Refrigerant Line Coupler - Installation.
9. Install the right front wheelhouse splash shield.
10. Lower the vehicle.





11. Remove the tape or plugs from the liquid line fitting and the receiver/drier (3).
12. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it onto the liquid line fitting. Use only the specified O-ring as it is 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.
13. Connect the rear section of the A/C liquid line (2) to the receiver/drier.
14. Install the bolt (1) that secures the rear section of the A/C liquid line to the receiver/drier. Tighten the bolt to 11 Nm (97 in. lbs.).





15. On Hybrid Electric Vehicle (HEV) models, install the Traction Power Inverter Module (TPIM) (1) and mounting bracket (2) .
16. Install the TPIM coolant recovery bottle .





17. Install the rear section of the liquid line (2) into the plastic retainer (3) located on the right inner fender (4).
18. Install the air cleaner housing and resonator (1) Air Cleaner Body - Installation.

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

19. On HEV models, reconnect the battery system using the service disconnect at the battery pack .
