Durango 2WD V8-5.7L Hybrid (2009)
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 refrigerant line to the A/C suction lineSee: A/C Suction Line -
Installation and See: Heating and Air Conditioning/Coupler HVAC/Service and Repair/Refrigerant Line Coupler - Installation.
9. Install the right front wheelhouse splash shield.
NOTE: 5.7L gas only engine shown. 5.7L HEV engine similar.
10. Lower the vehicle.
11. Remove the tape or plugs from the open suction line fittings.
12. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it and a new gasket onto the suction 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 front section of the A/C suction line (4) to the rear section of the A/C suction line (2) and install the retaining nut (1). Tighten the nut
to 23 Nm (17 ft. lbs.).
14. Install the air cleaner housing and resonatorSee: Filters/Air Cleaner Housing/Service and Repair/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.
15. On HEV models, reconnect the battery system using the service disconnect at the battery pack See: Hybrid Drive Systems/Battery System,
Hybrid Drive/Service and Repair
16. On gasoline only models, reconnect the negative battery cable.
17. Evacuate the refrigerant system See: Heating and Air Conditioning/Service and Repair/Refrigerant System Evacuate.
CAUTION: On HEV models, a small quantity of refrigerant oil may have been lost from the A/C compressor when the A/C suction line was
disconnected. Always replace the lost oil with the same amount of fresh clean ND-11 POE refrigerant oil prior to recharging the
A/C system. Never use PAG oil in an HEV model or operate the A/C system with an incorrect amount of oil in the system. Failure
to follow this caution may result in serious damage to the HEV A/C system.
18. Adjust the refrigerant oil level See: Heating and Air Conditioning/Specifications/Capacity Specifications/Refrigerant Oil Capacity.
19. Charge the refrigerant system See: Heating and Air Conditioning/Service and Repair/Refrigerant System Charge.

INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Heating and Air
Conditioning/Specifications/Capacity Specifications/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
