Condenser

Start by recovering the refrigerant through a halogen leak detector (J 39400-A). The intake duct requires both removal of the air intake duct and disconnection of its iat sensor connector. Proceed by taking off the radiator support followed by raising then supporting the vehicle. First take the air conditioner compressor hose assembly nut off the condenser before throwing away the o-ring. Check out the condenser first and remove the bolt securing the a/c evaporator tube while discarding the o-ring. From the condenser remove both the component radiator air upper baffle and remove the condenser itself from the radiator. The first step for assembly involves setting the condenser directly on the radiator then putting on the radiator air upper baffle. Use a new o-ring and fasten the evaporator a/c tube bolt onto the condenser using 16 n.m of torque (12 lb ft). Attach the condenser to the a/c compressor hose assembly nut after installing a second fresh o-ring but maintain a torque setting of 16 n.m (12 lb ft). After lowering the vehicle you must reattach the radiator support with the air intake duct in place. Finish installation by connecting the intake air temperature (IAT) sensor connector to the air intake duct followed by evacuating and charging the refrigerant system while conducting a halogen leak detector (J 39400-A) inspection on component fittings.

To take the condenser hva off, take the refrigerant first. For the 3.8 l engine, remove the intake air temperature (IAT) sensor connector form the air intake duct, and for the 5.7 l engine, remove the iat sensor and mass air flow (MAF) sensor connectors from the air intake duct. Displace the air intake duct for both engine types afterward displace our Radiator support and heave up the vehicle. Unscrew the air conditioning (A/C) compressor and condenser hose nut, and throw away the o-ring, then unscrew the a/c evaporator tube bolt at the condenser, and throw away its o-ring, also. Secondly, you should take off the Radiator air upper baffle from condenser and remove the condenser from Radiator. To install it, mount back the condenser onto the Radiator and mount the Radiator air upper baffle back. Change a new o-ring and apply a 16 n.m (12 lb ft) torque to the a/c evaporator tube bolt at the condenser. Install another new o-ring and connect the A/C Compressor and condenser hose nut at the condenser, while tightening this nut to 16 n.m (12 lb ft). Lower the vehicle, put Radiator support back in, air intake duct 5.7 and after that the air intake duct 3.8 l one. Join the connectors of the iat sensors and maf sensors for the 5.7 l engine, and iat sensor for the 3.8 l engine. Finally, recharge the a/c system and proceed with a leak test.

Evacuate and charge the refrigerant system and perform a leak test on the fittings using the Halogen Leak Detector (J 39400-A).
