Description
The A/C refrigerant lines and pipes are used to carry the refrigerant between the various A/C system components.
Any kinks or sharp bends in the refrigerant lines and hoses will reduce the capacity of the entire A/C system and can
reduce the flow of refrigerant within the system.
Operation
High pressure is produced in a refrigerant system when the A/C compressor is operating. Extreme care must be
exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a good
practice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition and
properly routed. Depending on vehicle, model and market application, refrigerant lines are connected to each other or
other A/C system components with block-type or quick-connect type fittings. To ensure the integrity of the refrigerant
system, O-rings and/or gaskets may be used to seal the refrigerant system connections. The refrigerant lines and
hoses cannot be repaired and must be replaced if leaking or damaged.
WARNING!
The A/C system contains refrigerant under high pressure. Repairs should only be performed by qualified service
personnel. Serious or fatal injury may result from improper service procedures.
If accidental A/C system discharge occurs, ventilate the work area before resuming service. Large amounts of
refrigerant released in a closed work area will displace the oxygen and cause suffocation and serious or fatal
injury.
CAUTION:
Never add R-12 to a refrigerant system designed to use R-134a. Do not use R-12 equipment or
parts on an R-134a A/C system. These refrigerants are not compatible and damage to the A/C sys-
tem will result.
CAUTION:
Never use R-12 refrigerant oil in an A/C system designed to use R-134a refrigerant oil. These refrig-
erant oils are not compatible and damage to the A/C system will result.
CAUTION:
Do not run the engine with a vacuum pump in operation or with a vacuum present within the A/C
system. Failure to follow this caution will result in serious A/C compressor damage.
CAUTION:
Do not overcharge the refrigerant system. Overcharging will cause excessive compressor head
pressure and can cause compressor noise and A/C system failure.

connectors.
NOTE: The refrigerant recovery/recycling station
connectors are connected to the vehicle in the fol-
lowing way:
• BLUE connector (1) is connected to the A/C low side
fitting.
• RED connector (2) is connected to the A/C high side
fitting.
A/C System Evacuation
CAUTION:
Do NOT run the engine with a vacuum pump in operation or with a vacuum present within the A/C
system. Failure to follow this caution will result in serious A/C compressor damage.
NOTE :
Special effort must be used to prevent moisture from entering the A/C system oil. Moisture in the oil is very difficult
to remove and will cause a reliability problem with the A/C compressor.
If the refrigerant system has been open to the atmosphere, it must be evacuated before the system can be filled.
Moisture and air mixed with the refrigerant will raise the compressor high pressure above acceptable operating lev-
els. This will reduce the performance of the A/C system and damage the A/C compressor. Moisture will boil at near
room temperature when exposed to vacuum.
NOTE :
When connecting the service equipment coupling to the line fitting, verify that the valve of the coupling is fully closed.
This will reduce the amount of effort required to make the connection.
To evacuate the refrigerant system:
1. With the engine OFF, connect a suitable charging station, refrigerant recovery machine or a manifold gauge set with vacuum pump and refrigerant recovery equipment. Do not operate the engine with a vacuum on the A/C
system.
2. Open the suction and discharge valves and start the vacuum pump. The vacuum pump should run a minimum of 45 minutes prior to charge to eliminate all moisture in system. When the suction gauge reads to the lowest
degree of vacuum possible for 30 minutes, close all valves and turn off vacuum pump. If the system fails to
reach specified vacuum, the refrigerant system likely has a leak that must be corrected. If the refrigerant system
maintains specified vacuum for at least 30 minutes, start the vacuum pump, open the suction and discharge
valves. Then allow the system to evacuate an additional 10 minutes.
3. Close all valves.
4. Turn off and disconnect the vacuum pump.
5. Charge the refrigerant system.
A/C System Recharge
After all refrigerant system leaks have been repaired and the refrigerant system has been evacuated, a refrigerant
charge can be injected into the system.
CAUTION:
A small amount of refrigerant oil is removed from the A/C system each time the refrigerant system
is recovered and evacuated. Before charging the A/C system, you MUST replenish any oil lost dur-
ing the recovery process.
1. Evacuate the refrigerant system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Con- ditioning).

3. Open both the suction and discharge valves, then open the charge valve to allow the refrigerant to flow into the system.
4. When the transfer of refrigerant has stopped, close both the suction and discharge valves.
5. If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle and set the heating-A/C system controls so that the A/C compressor is operating and the blower motor is running
at its lowest speed setting. Run the engine at a steady high idle (about 2000 RPM).
6. Open the low-pressure valve to allow the remaining refrigerant to transfer to the refrigerant system.
WARNING!
Take care not to open the discharge (high pressure) valve at this time. Failure to follow this warning could result
in possible personal injury or death.
7. Disconnect the refrigerant recovery/recycling station from the refrigerant system service ports.
8. Reinstall the caps onto the refrigerant system service ports.
Compressor
Description
Vehicles equipped with the 1.6L & 1.8L & 2.0L engine use a SD7V16 clutch-less compressor. The 2.4L equipped
vehicles use a V5 clutch-less compressor. The compressor is a variable displacement compressor. The largest dis-
placement is 161.3 ml/r, displacement range of 5% to 100%.
CAUTION:
DONT run the engine with a vacuum pump in operation or with a vacuum present within the A/C
system. Failure to follow this caution will result in serious A/C compressor damage.
NOTE :
The compressor drive hub and the pulley and bearing assembly cannot be serviced separately from the A/C com-
pressor. In the event of drive hub or pulley and bearing assembly damage or failure, the A/C compressor, drive hub
and pulley and bearing must be replaced as an assembly.
Operation
The A/C compressor is controlled by the Engine Control Module (ECM), depending on engine application. The ECM
calculates compressor displacement required by A/C system load and demand by monitoring vehicle speed, A/C high
side pressure, engine speed, evaporator temperature, accelerator pedal position, ambient temperature and A/C-
Heater request signals. The ECM then sends a pulse width modulated signal to the A/C compressor control solenoid
to increase or decrease refrigerant flow through an orifice located within the compressor housing. The amount of
refrigerant allowed to pass through the orifice in the compressor determines the head pressure which controls the
angle of the swash plate, which in turn, determines the amount of compressor displacement. When there is no
demand for A/C, the swashplate is adjusted to nearly a zero degree angle, which removes compressor torque drag
from the engine.
NOTE :
The A/C compressor cannot be repaired and it must be replaced if found inoperative or damaged. If an internal fail-
ure of the A/C compressor has occurred, the A/C accumulator and the A/C liquid line must also be replaced.
Removal & Installation - 1.6L & 1.8L & 2.0L
