1. Disconnect and isolate the negative battery cable.

2. Recover the refrigerant from the refrigerant system. See REFRIGERANT SYSTEM RECOVERY.

3. Remove the engine air cleaner housing (refer to REMOVAL for 3.7L - SERVICE INFORMATION or

REMOVAL for 4.0L - SERVICE INFORMATION ).

4. Remove the secondary retaining clip and using the proper A/C line disconnect tool (Special Tool Kit

7193 or equivalent), disconnect the A/C liquid line (1) from the condenser tube (2). See REMOVAL.

WARNING:

Refer to the applicable warnings and cautions for this system before
performing the following operation. See WARNING, and CAUTION. Failure
to follow the warnings and cautions could result in possible personal
injury or death.

CAUTION: Before removing the A/C condenser, note the location of each of the

radiator/condenser air seals. These air seals are used to direct air through
the A/C condenser and radiator. The air seals must be reinstalled in their
proper locations in order for the A/C and engine cooling systems to
perform as designed.

5. Remove the grille. Refer to REMOVAL .

6. If equipped with an automatic transmission, disconnect the transmission cooler lines from the

transmission cooler portion of the A/C condenser. Refer to REMOVAL .

7. Position the right side condenser air seal out of the way to gain access to the discharge line fitting and the

lower condenser retaining bolt.

8. Remove the nut (4) that secures the A/C discharge line (5) to the A/C condenser (3) and disconnect the

discharge line.

9. Remove the two bolts (2) that secure the A/C condenser to the right side of the radiator (1).

10. Carefully lift the A/C condenser straight up to disengage the condenser mounting brackets from the

radiator and remove the condenser from the vehicle.

11. If required, remove the A/C receiver/drier from the A/C condenser. See REMOVAL.

12. Remove and discard the O-ring seals and gasket and install plugs in, or tape over the opened refrigerant

line fittings and the condenser and receiver/drier ports.

NOTE:

Rotate and tilt the A/C discharge line as necessary to disconnect it from
the A/C condenser.

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C

refrigerant system. See REFRIGERANT OIL LEVEL. Failure to properly

1. Remove the tape or plugs from the opened refrigerant line fittings and the receiver/drier and condenser

ports.

2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and a new gasket onto the

adjust the refrigerant oil level will prevent the A/C system from operating
as designed and can cause serious A/C compressor damage.

CAUTION: The radiator/condenser air seals must be reinstalled in their proper

locations in order for the A/C and engine cooling systems to perform as
designed.

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. See REFRIGERANT OIL LEVEL.

NOTE:

If only the A/C condenser is being replaced, add 30 milliliters (1 fluid ounce) of
refrigerant oil to the refrigerant system. Use only refrigerant oil of the type
recommended for the A/C compressor in the vehicle.

NOTE:

Replacement of the refrigerant line O-ring seals and gaskets is required anytime
a refrigerant line is opened. Failure to replace the rubber O-ring seals and metal
gaskets could result in a refrigerant system leak.

refrigerant line fittings. 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.

3. If removed, install the A/C receiver/drier onto the A/C condenser (3). See INSTALLATION.

4. Position the A/C condenser into the engine compartment and install it onto the condenser mounting

brackets.

5. Install the two bolts (2) that secure the A/C condenser to the right side of the radiator (1). Tighten the

bolts to 5 N.m (44 in. lbs.).

6. Connect the A/C discharge line (5) to the A/C condenser and install the retaining nut (4). Tighten the nut

to 22.5 N.m (200 in. lbs.).

7. Reposition the right side condenser air seal.

8. If equipped with an automatic transmission, connect the transmission cooler lines to the transmission

cooler portion of the A/C condenser. Refer to INSTALLATION .

9. Install the grille. Refer to INSTALLATION .

10. Connect the A/C liquid line (1) to the condenser tube (2) and install the secondary retaining clip. See

INSTALLATION.

11. Install the engine air cleaner housing (refer to INSTALLATION for 3.7L - SERVICE INFORMATION

or INSTALLATION for 4.0L - SERVICE INFORMATION ).

12. Reconnect the negative battery cable.

13. Evacuate the refrigerant system. See REFRIGERANT SYSTEM EVACUATE.

14. If the A/C condenser is being replaced, add 30 milliliters (1 fluid ounce) of refrigerant oil to the

refrigerant system. 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. See

NOTE:

Rotate and tilt the A/C discharge line as necessary to connect it to the A/C
condenser.
