WARNING: REVIEW THE WARNINGS AND CAUTIONS IN THE GENERAL INFORMATION SECTION NEAR THE FRONT OF THIS GROUP BEFORE PERFORMING THE FOLLOWING OPERATION.

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.

REMOVAL

(1) Disconnect and isolate the battery negative cable.

(2) Recover the refrigerant from the refrigerant system. See Refrigerant Recovery in the Service Procedures section of this group.

(3) Disconnect the refrigerant line fitting that secures the discharge line to the condenser inlet (Fig.

37). Install plugs in, or tape over all of the opened refrigerant line fittings.

(4) Disconnect the refrigerant line fitting that secures the liquid line to the condenser outlet. Install plugs in, or tape over all of the opened refrigerant line fittings.

(5) Remove the two screws that secure the radiator and fan shroud module to the inside of the upper radiator crossmember.

(6) On models equipped with a V-8 engine, remove the radiator from the engine compartment. Refer to Cooling Systems for the procedures.

(7) Remove the two screws that secure the condenser to the outside of the upper radiator crossmember (Fig. 38).

(8) Tilt the top of the radiator and fan shroud module towards the engine, using care not to damage the radiator fins on the engine cooling fan.

(9) With the radiator and fan shroud module tilted, carefully lift the condenser upwards until the lower condenser mounts are clear of the isolators in the lower crossmember.

(10) Remove the condenser from the vehicle.

INSTALLATION

(1) With the radiator and fan shroud module tilted towards the engine, carefully position the lower condenser mounts in the lower crossmember isolators.

(2) Reinstall the two screws that secure the condenser to the outside of the upper radiator crossmember and tighten to 10.7 N*m (95 in. lbs.).

(3) On models equipped with a V-8 engine, reinstall the radiator to the engine compartment. Refer to Cooling Systems for the procedures.

(4) Reinstall the two screws that secure the radiator and fan shroud module to the inside of the upper radiator crossmember.

(5) Remove the plugs or tape from the refrigerant line fittings on the liquid line and the condenser outlet.

Connect the liquid line to the condenser outlet.

Tighten the fitting to 25.99 63.39 N*m (230 630 in.

lbs.).

(6) Remove the plugs or tape from the refrigerant line fittings on the discharge line and the condenser inlet. Connect the discharge line to the condenser inlet. Tighten the fitting to 25.99 63.39 N*m (230 630 in. lbs.).

(7) Check that all of the condenser and radiator air seals are in their proper locations.

(8) Connect the battery negative cable.

(9) Evacuate the refrigerant system. See Refrigerant System Evacuate in the Service Procedures section of this group.

(10) Charge the refrigerant system. See Refrigerant System Charge in the Service Procedures section of this group.

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.
