INSTALLATION

2.7L ENGINE

NOTE: Be certain to check the refrigerant oil level if the A/C compressor is being replaced (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT OIL - STANDARD PROCEDURE - REFRIGERANT
OIL LEVEL). Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.

PLUMBING

CAUTION: Use care not to deform or damage the
automatic transmission cooler lines and retaining
bracket when repositioning the A/C compressor.

NOTE: The bolt that secures the transmission
cooler line bracket to the A/C compressor must be
installed through the bracket and the lower front
mounting hole of the compressor prior to final
positioning of the compressor to the cylinder
block.

1. Loosely install the bolt (3) that secures the auto-

matic transmission cooler line bracket (4) to the
A/C compressor (5) and position the compressor,
bracket and bolt to the cylinder block (6).

2. Loosely install the bolts (1 and 2) that secure the

A/C compressor to the cylinder block.

3. Tighten the three bolts in the following order:

1. Upper front bolt to 26 N·m (19 ft. lbs.).

2. Lower front bolt to 26 N·m (19 ft. lbs.).

3. Rear bolt to 50 N·m (37 ft. lbs.).

4. Install the front end splash shields (Refer to 23 - BODY/EXTERIOR/FRONT END SPLASH SHIELDS - INSTAL-

LATION).

5. Lower the vehicle.

6. Remove the tape or plugs from the opened fittings

on the A/C suction line (3) and the A/C discharge
line (4) and the compressor ports.

7. Lubricate the new dual plane seals with clean

refrigerant oil and install them onto the suction and
the discharge line fittings. Use only the specified
seals 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 vehi-
cle.

8. Connect the suction and discharge lines onto the

A/C compressor (5).

9. Install the nuts (2) that secure the suction and dis-

charge lines to the A/C compressor. Tighten the
nuts to 23 N·m (17 ft. lbs.).

10. Connect the engine wire harness to the compres-

sor clutch field coil connector (1).

11. Install the accessory drive belt (Refer to 7 -

COOLING/ACCESSORY DRIVE/BELTS-DRIVE -
INSTALLATION).

12. Replace the receiver/drier if the A/C compressor is being replaced due to an internal failure (Refer to 24 -

HEATING & AIR CONDITIONING/PLUMBING/RECEIVER/DRIER - REMOVAL) and (Refer to 24 - HEATING &
AIR CONDITIONING/PLUMBING/RECEIVER/DRIER - INSTALLATION).

13. Install the air cleaner housing (Refer to 9 - ENGINE/AIR INTAKE SYSTEM/AIR CLEANER HOUSING - INSTAL-

LATION).

14. Reconnect the negative battery cable.

15. Evacuate the refrigerant system (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD

PROCEDURE - REFRIGERANT SYSTEM EVACUATE).

16. Charge the refrigerant system (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PRO-

CEDURE - REFRIGERANT SYSTEM CHARGE).
