NOTE: The compressor clutch assembly can be serviced with the refrigerant system fully-charged. Typical A/C compressor shown in illustrations. 1. Disconnect and isolate the negative battery cable. 2. Remove the accessory drive belt. 3. Disconnect the engine wire harness from the compressor clutch field coil connector (1) located on the top of the A/C compressor (5). 4. Remove the bolts that secure the A/C compressor to the engine and support the A/C compressor. 5. Carefully remove the compressor clutch field coil connector and wire lead from the connector bracket (2). 6. Remove the compressor shaft bolt (3). A band-type oil filter wrench or a strap wrench may be used to hold the clutch plate (4) from rotating during bolt removal. CAUTION: Do not pry between the clutch plate and the pulley and bearing assembly to remove the clutch plate from the compressor shaft as this may damage the clutch plate. NOTE: Use care not to lose any clutch shim(s) during removal of the clutch plate, as they may be reused during the clutch plate installation process. 7. Tap the clutch plate (2) lightly with a plastic mallet to release it from the splines on the compressor shaft (1) and remove the clutch plate and shim(s) (3). 8. Using snap ring pliers (2), remove the snap ring (1) that secures the pulley and bearing assembly (3) to the front of the A/C compressor and remove the pulley and bearing assembly. 9. Using snap ring pliers (Special Tool C-4574 or equivalent) (1), remove the snap ring (4) that secures the compressor clutch field coil (2) to the front of the A/C compressor (3) and remove the field coil. INSTALLATION NOTE: Typical A/C compressor shown in illustrations.

CAUTION: To prevent possible Electrostatic Discharge damage to the Powertrain Control Module (PCM), Do Not touch the connector pins or soldered components on the circuit. Service of the PCM should normally consist of either replacement of the PCM or a Programmable Read Only Memory (PROM) change. If the diagnostic procedures call for the PCM to be replaced, the engine calibrator (PROM) and PCM should be checked first to see if they are the correct parts. If they are remove the PROM from the faulty PCM and install it in the new service PCM. THE SERVICE PCM WILL NOT CONTAIN A PROM. Diagnostic Trouble Code (DTC) 51 indicates the PROM is installed improperly or has malfunctioned. When DTC 51 is obtained, check the PROM installation for bent pins or pins not fully seated in the socket. If the PROM is installed correctly and DTC 51 still shows, replace the PROM. Important: When replacing the production PCM with a service PCM (controller), it is important to transfer the Broadcast code and production PCM number to the service PCM label. Please do not record on PCM cover. This will allow positive identification of PCM parts throughout the service life of the vehicle. CAUTION: To prevent internal PCM damage, the ignition must be “OFF” when disconnecting or reconnecting power to PCM (for example, battery cable, PCM pigtail, PCM fuse, jumper cables, etc.). REMOVE OR DISCONNECT 1. Negative battery cable. 2. Right side sound insulator. 3. Vacuum center. 4. Connectors to PCM. 5. PCM. 6. PROM access cover. 7. PROM from PCM. INSTALL OR CONNECT 1. PROM to PCM. 2. PROM access cover. 3. PCM. 4. Connectors to PCM. 5. Vacuum center. 6. Right side sound insulator. 7. Negative battery cable.

To ensure maximum drive belt life and proper component operation, replacement drive belts (8620) must be the same type and size as the original drive belts . When installing a new drive belt , ensure that it is properly seated on the pulleys. NOTE: Mark the direction of rotation on the drive belt with a marking pen to ensure correct installation if the drive belt is to be reused. Failure to do so may result in drive belt noise. Drive Belt, A/C Compressor Removal 1. Loosen the A/C compressor drive belt idler pulley tensioner bolt. 2. Loosen the A/C compressor drive belt idler pulley adjustment bolt. 3. Remove the A/C compressor drive belt from the A/C compressor clutch pulley (2E884) , A/C compressor drive belt idler pulley and the crankshaft pulley (6312) . Installation 1. Inspect the pulleys for warping or abnormal wear. Replace any damaged pulley. To replace the A/C compressor clutch pulley , refer to Section 12-03B. To replace crankshaft pulley , refer to Section 03-01. 2. Install the A/C compressor drive belt on the A/C compressor clutch pulley , A/C compressor drive belt idler pulley, and crankshaft pulley . 3. Adjust the A/C compressor drive belt tension. Refer to the procedure in this section. 4. Tighten the A/C compressor drive belt idler pulley tensioner bolt securely. Drive Belt, Generator Removal 1. Raise and support the vehicle. 2. Remove the RH engine and transmission splash shield (6775) . 3. Loosen the inner and outer generator-to-generator regulator mounting bracket bolts. 4. Loosen the generator locking bolt.

ISOLATING COMPRESSOR NOTE: Only compressors with stem-type service valves can be isolated. 1) Connect service gauge set to the compressor service valves and open compressor valves slightly (turn in clockwise). Start engine and operate air conditioning. Slowly turn compressor suction valve clockwise toward closed (front-seated) position. REFRIGERANT OIL Only new, pure, moisture-free refrigerant oil should be used in the air conditioning system. This oil is highly refined and dehydrated to a point where moisture content is less than 10 parts per million. The oil container must be tightly closed at all times when not in use, or moisture will be absorbed into the refrigerant oil from the air. ATSUGI ROTARY VANE CLUTCH R & I Removal When replacing compressor clutch, be careful not to scratch shaft or bend pulley. When removing center bolt, hold clutch disc with Clutch Holder (KV99231010). Using Hub Puller (KV998VR001 & KV99231010), remove clutch disc. When removing pulley, remove lock nut with Hub Socket (KV99235160).
