Kia Carnival (2009+). Instruction — part 538

4. Check operation of the magnetic clutch.Connect the compressor side terminals to the battery (+) terminal and the

ground battery (-) terminal to the compressor body.
Check the magnetic clutch operating noise to determine the condition.

DISASSEMBLY

1. Remove the center bolt (A) while holding the disc & hub assembly with a commercially available disc & hub

assembly bolt remover; Special tool number 09977-29000.

TORQUE: 10~15N.m (1.02~1.53kgf.m, 7.37~11lbf.ft)

2. Remove the disc & hub assembly (A) and shim (gap washer) (B), taking care not to lose the shims. If the clutch

needs adjustment, increase or decrease the number and thickness of shims as necessary, then reinstall the disc &
hub assembly, and recheck its clearance (Refer to HA-19).

3. If you removal the field coil, remove retainer ring (A) with retainer ring pliers.

- Be careful not to damage the pulley (B) and compressor during removal/installation.
- Once retainer ring (A) is removed, replace it with a new one.

4. Remove the screw (A) from the field coil ground terminal. Remove the retainer ring (B) and then remove the field

coil (C) from the shaft with a puller. Be careful not to damage the coil and compressor.

5. Reassemble the compressor clutch in the reverse order of disassembly, and note these items :

A. Clean the pulley and compressor sliding surfaces with non-petroleum solvent.
B. Install new retainer rings, and make sure they are fully seated in the groove.
C. Make sure that the pulley turns smoothly after its reassembled.

Oil Specification

1. The HFC-134a system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral

compressor oil. The two oils must never be mixed.

2. Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the model of

compressor.

Handling of Oil

1. The oil should be free from moisture, dust, metal powder, etc.

2. Do not mix with other oil.

3. The water content in the oil increases when exposed to the air. After use, seal oil from air immediately. (HFC-134a

Compressor Oil absorbs moisture very easily.)

4. The compressor oil must be stored in steel containers, not in plastic containers.

Compressor oil check

The oil used to lubricate the compressor is circulating with the refrigerant.
Whenever replacing any component of the system or a large amount of gas leakage occurs, add oil to maintain the
original amount of oil.

Oil total volume in system:
120±10cc (4.05±0.34 fl.oz)

Oil Return Operation

There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculates with the refrigerant in the system. When checking the amount of
oil in the system, or replacing any component of the system, the compressor must be run in advance for oil return
operation. The procedure is as follows:

1. Open all the doors and the engine hood.

2. Start the engine and air conditioning switch to "ON" and set the blower motor control knob at its highest position.

3. Run the compressor for more than 20 minutes between 800 and 1,000 rpm in order to operate the system.

4. Stop the engine.

Replacement of Component Parts

When replacing the system component parts, supply the following amount of oil to the component parts to be installed.

Component parts to be installed

Amount of Oil

Evaporator

50 cc (1.70 fl.oz)

Condenser

30 cc (1.02 fl.oz)

Receiver/dryer

30 cc (1.02 fl.oz)

Refrigerant line (One piece)

10 cc (0.34 fl.oz)

For compressor replacement, subtract the volume of oil drained from the removed compressor from the specified
volume, and drain the calculated volume of oil from the new compressor:
The specified volume - volume of removed compressor = volume to drain from the new compressor.

Even if no oil is drained from the removed compressor, don’t drain more than 50cc from new compressor.
