1. Position the A/C compressor (2) onto the mounting
bracket (3) located on the right side of the cylinder
block (4).
2. Install and hand tighten the four bolts (1) that
secure the A/C compressor to the mounting
bracket.
3. Tighten the bolts that secure the A/C compressor to
themountingbracketto23Nꞏm(17ft.lbs.).
4. Remove the tape or plugs from the opened refrig-
erant line fittings and the compressor ports.
5. Lubricate new seals with clean refrigerant oil and
install them onto the refrigerant line fittings. Use
only the specified seals as they are made of a spe-
cial material for the R-134a system. Use only
refrigerant oil of the type recommended for the A/C
compressor in the vehicle.
6. Install the A/C suction and discharge line assembly
(2) onto the A/C compressor (3).
7. Install the bolt (1) that secures the refrigerant line
assembly to the A/C compressor. Tighten the bolt
to 23 Nꞏm (17 ft. lbs.).
8. Connect the wire harness to the clutch field coil
wire lead connector (4).
9. Install the accessory drive belt (Refer to 7 - COOL-
ING/ACCESSORY DRIVE/BELTS-DRIVE - INSTAL-
LATION).
10. Reconnect the negative battery cable.
11. Evacuate the refrigerant system (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD
PROCEDURE - REFRIGERANT SYSTEM EVACUATE).
12. Charge the refrigerant system (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PRO-
CEDURE - REFRIGERANT SYSTEM CHARGE).

(15 ft. lbs.).
8. Connect the wire harness connector to the A/C
compressor clutch coil connector (4).
9. Install the accessory drive belt (Refer to 7 - COOL-
ING/ACCESSORY DRIVE/BELTS-DRIVE - INSTAL-
LATION).
