the hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold.
High pressures are produced in the refrigerant system when the air conditioning compressor is operating. Extreme care must be exercised to make sure
that each of the refrigerant system connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose refrigerant lines at least
once a year to make sure they are in good condition and properly routed.
CAUTION: Before removing the condenser, note the location of each of the radiator and condenser air seals. These seals are used to direct air
through the condenser and radiator. The air seals must be reinstalled in their proper locations in order for the air conditioning and engine cooling
systems to perform as designed.
1. Carefully position the condenser in the vehicle.
2. Install the bolts that secure the upper condenser and transmission cooler.
3. Remove the tape or plugs from the refrigerant line fittings on the condenser inlet and the discharge line. Connect the discharge line to the
condenser inlet. Tighten the retaining nut to 28 Nm (250 in. lbs.).
4. Remove the tape or plugs from the refrigerant line fittings on the condenser outlet and the liquid line. Connect the liquid line to the condenser
outlet. Tighten the retaining nut to 28 Nm (250 in. lbs.).
5. Install the headlamp mounting module and front fascia. Refer to Body for the procedure.
6. Install the engine air filter inlet duct.
7. Install the bolts that secure the radiator to the upper crossmember.
8. Install the nuts that secure the hood latch and brace to the upper crossmember.
9. Install the headlamps in their mounts.
10. Install the screws attaching the grille and headlamp mounting module to the upper crossmember of the vehicle. Refer to Body for this and further
steps in the procedure.
11. Evacuate and Recharge the refrigerant system.
12. Connect the battery negative cable.
NOTE: If the condenser is replaced, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrigerant system. Use only refrigerant oil of the type
recommended for the compressor in the vehicle.
