CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
 When the compressor is removed, store it in the sam e way at it is when mounted on the car. Failure
to do so will cause lubricant to enter the low-pressure chamber.
 When connecting tubes, always use a to rque wrench and a back-up wrench.
 After disconnecting tubes, immediately plug all op enings to prevent entry of dust and moisture.
 When installing an air conditioner in the vehicle, connect the pipes at the final stage of the operation.
Never remove the seal caps of pipes and other compon ents until just before required for connection.
 Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
 Thoroughly remove moisture from the refriger ation system before charging the refrigerant.
 Always replace used O-rings.
 When connecting tubes, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
 O-ring must be closely att ached to the groove of tube.
 When replacing the O-ring, be careful not to damage O-ring and tube.
 Connect tube until a click can be heard, then tighten the nut or bolt by hand. Make sure that the O-
ring is installed to tube correctly.
 After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
Precaution for Service of CompressorINFOID:0000000001328156
 Plug all openings to prevent moisture and foreign matter from entering.
 When the compressor is removed, store it in th e same way at it is when mounted on the car.
 When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compressor”
exactly. Refer to ATC-22, "
Maintenance of Lubricant Quantity in Compressor".
 Keep friction surfaces between clut ch and pulley clean. If the surface is contaminated with lubricant,
wipe it off by using a clean w aste cloth moistened with thinner.
 After compressor service operation, turn the compr essor shaft by hand more than five turns in both
directions. This will equally dist ribute lubricant inside the compressor. After the compressor is
installed, let the engine idle and operate the compressor for one hour.
 After replacing the compressor magnet clutch, ap ply voltage to the new one and check for normal
operation.

REFRIGERATION SYSTEM
Evaporator intake air temperature is less than 20°C (68 °F).
Engine is running at speeds less than 1,500 rpm.
This is because the V-6 compressor prov ides a means of “capacity” control.
2. The V-6 variable compressor provides refrigerant c ontrol under varying conditions. During cold winters, it
may not produce high refrigerant pressure discharge (compared to previous units) when used with air
conditioning systems.
3. A “clanking” sound may occasionally be heard during re frigerant charge. The sound indicates that the tilt
angle of the wobble (swash) plate has changed and is not a malfunction.
4. For air conditioning systems with the V-6 compresso r, the clutch remains engaged unless: the system
main switch, fan switch or ignition switch is tur ned OFF. When ambient (outside) temperatures are low or
when the amount of refrigerant is insufficient, t he clutch is disengaged to protect the compressor.
DESCRIPTION
General
The variable compressor is a swash plate type that c hanges piston stroke in response to the required cooling
capacity.
The tilt of the wobble (swash) plate allows the piston’ s stroke to change so that refrigerant discharge continu-
ously change from 14.5 to 184 cm
3 (0.885 to 11.228 cu in).

Operation
1. Control Valve
- By changing high-pressure valve lift amount, built-in electronic control valve executes the following:
 Controls high-pressure valve discharge amount.
 Changes crankcase pressure in compressor.
 Changes angle of wobble (swash) plate.
- Amount of high-pressure valve lift is determined by factors below.
 Low-pressure applied to diaphragm
 Spring load of set spring
 Balance of magnetic force generated in magnet coil
- Electronic control valve (ECV) magnet coil receives
electric signal (duty control) from unified meter and A/
C amp. Then, magnetic force generated by electric cu rrent is changed to control high-pressure valve lift
amount.
2. Maximum Cooling
High-pressure valve is closed by magnetic force gener ated by electric signal sent from unified meter and
A/C amp. At this time, cylinder moves full stroke due to pressure balance between inside crankcase (Pc)
and suction line (Ps).
Under this condition, the wobble (swash) plat e is set to the maximum stroke position.
3. Capacity Control When no electric signal is sent from unified meter and A/C amp. (current: OFF), high-pressure valve is
opened by spring force.
Since suction pressure is low, it makes the su ction port close and the discharge port open. Thus, crank-
case pressure becomes high as high-pressure enters the crankcase.
- The force acts around the journal pin near the wobble (swash) plate, and is generated by the pressure dif-
ference before and behind the piston.
- The drive lug and journal pin are located where t he piston generates the highest pressure. Piston pres-
sure is between suction pressure Ps and discharge pressu re Pd, which is close to suction pressure Ps. If
crankcase pressure Pc rises due to capacity contro l, the force around the journal pin makes the wobble
(swash) plate angle decrease and also the piston stroke decrease. In other words, crankcase pressure

Maintenance of Lubricant Quantity in CompressorINFOID:0000000001328166
The lubricant in the compressor circulates through the system with the refrigerant. Add lubricant to compres-
sor when replacing any component or after a large refriger ant leakage occurred. It is important to maintain the
specified amount.
If lubricant quantity is not maintained properly, the following malfunctions may result:
 Lack of lubricant: May lead to a seized compressor.
 Excessive lubricant: Inadequate cooling (thermal exchange interference)

LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT
1. Before connecting recovery/recycling recharging equipm ent to vehicle, check recovery/recycling recharg-
ing equipment gauges. No refrigerant pressure should be displayed. If NG, recover refrigerant from equip-
ment lines.
2. Connect recovery/recycling recharging equipment to vehicle. Confirm refrigerant purity in supply tank
using recovery/recycling recharging equipment and refrigerant identifier. If NG, refer to AT C - 4 , "
Precaution
for Working with HFC-134a (R-134a)".
3. Confirm refrigerant purity in vehicle A/C system us ing recovery/recycling recharging equipment and refrig-
erant identifier. If NG, refer to AT C - 4 , "
Precaution for Working with HFC-134a (R-134a)".
4. Discharge refrigerant into the refrigerant recove ry/recycling equipment. Measure lubricant discharged into
the recovery/recycling equipment.
5. Drain the lubricant from the old (removed) comp ressor into a graduated container and recover the amount
of lubricant drained.
6. Drain the lubricant from the new compressor into a separate, clean container.
7. Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this
lubricant to new compressor through the suction port opening.
8. Measure an amount of new lubricant equal to the am ount recovered during discharging. Add this lubricant
to new compressor through the suction port opening.
9. If the liquid tank also needs to be replaced, add another 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant at
this time.
Do not add this 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant when replaces the compressor only.
