Removal of Manifold Gauge Set
WARNING!
High pressure side is under high pressure.
Therefore, be careful not to get injured
especially on your eyes and skin.

For the A/C system charged with the specified amount of
refrigerant, remove manifold gauge set as follows:
1) Close low pressure side valve of manifold gauge set. (The high pressure side valve is closed continuously
during the process of charging.)
2) Close refrigerant container valve.
3) Stop engine.
4) Using shop rag, remove charging hoses from service valves. This operation must be performed quickly.
5) Put caps on service valves.
Check A/C System for Refrigerant Leaks
Whenever a refrigerant leak is suspected in the system
or any service operation has been performed which may
result in malfunction of lines and connections, it is
advisable to check for leaks.
Common sense should be used during refrigerant leak
test, since the need and extent of any such test will, in
general, depend upon the nature of a complaint and the
type of a service performed on the system.
Liquid leak detector
WARNING!
• To prevent explosions and fires, make sure that there are no flammables in the vicinity.
• When the refrigerant exposed to fire, it turns into a poisonous gas (phosgene). Do
not inhale this gas.

There is a number of fittings and places throughout the
A/C system where a liquid leak detector solution may be
used to pinpoint refrigerant leaks.
By merely applying the solution to the area in question
with a swab, such as attached to the cap of a vial,
bubbles will form within seconds if there is a leak.
For confined areas, such as sections of the evaporator
and condenser, an electronic (refrigerant) leak detector
is more practical fo r determining leaks.

Condenser Assembly On-Vehicle InspectionS7RS0B7216002
Check the followings.
• Clog of condenser fins If any clog is found, cond enser fins should be washed
with water and should be dried with compressed air.
• Condenser fins for leakage and breakage If any defects are found, repair or replace condenser.
• Condenser fittings for leakage. If any defects are found, repair or replace condenser.
Condenser Assembly Removal and InstallationS7RS0B7216003
CAUTION!
Do not damage condenser fins. If condenser
fin is bent, straighten it by using flat head
screwdriver or pair of pliers.

Removal
1) Recover refrigerant from A/C system referring to “Operation Procedure for Refrigerant Charge”.
NOTE
The amount of removed compressor oil must
be measured for replenishing compressor
oil.

2) Remove front bumper referring to “Front Bumper and Rear Bumper Components in Section 9K”.
3) Disconnect discharge hose (1) and liquid pipe (2) from condenser assembly (3).
4) Remove condenser assembly mounting bolts (4).

Expansion Valve Removal and InstallationS7RS0B7216010
Removal1) Recover refrigerant fr om the A/C system with
recovery and recycling equipment referring to
“Recovery” in “Operation Procedure for Refrigerant
Charge”.
2) Loosen a bolt (1) and remove pipes from expansion valve (2).
3) Loosen bolts (3) and remove expansion valve.
Installation
Reverse removal procedure noting the following
instructions.
• Apply compressor oil to O-ring of expansion valve and pipes.
• Evacuate and charge the A/C system referring to “Evacuation” and “Charge” in “Operation Procedure
for Refrigerant Charge”.
Tightening torque
Expansion valve mount bolt: 3.5 N·m (0.35 kgf-m,
2.5 lb-ft)
Expansion Valve InspectionS7RS0B7216011
Refer to “A/C System Performance Inspection”.
A/C Refrigerant Pressure Sensor and Its Circuit
Inspection
S7RS0B7216012
1) Disconnect A/C refrigerant pressure sensor connector.
2) Turn ignition switch to ON position.
3) Check if voltage between “RED” wire terminal and “ORN” wire terminal of A/C refrigerant pressure
sensor connector is 4.75 V to 5.25 V.
If not, check A/C refrigerant pressure sensor circuit.
4) Connect A/C refrigerant pressure sensor connector with ignition switch turned OFF.
5) Connect manifold gauge set to the charging valves.
6) Check A/C refrigerant pressure sensor voltage of ECM connector referring to “A/C System Inspection
at ECM”.
If voltage is not as specified below, replace A/C
refrigerant pressure sensor. A/C refrigerant pressure sensor voltage
specifications (A/C refrigerant pressure measured
by manifold gauge)
0.8 MPa (8.0 kg/cm2, 116 psi): 1.46 – 1.71 V
1.4 MPa (14 kg/cm2, 203 psi): 2.28 – 2.53 V
1.6 MPa (16 kg/cm2, 232 psi): 2.55 – 2.80 V
1.8 MPa (18 kg/cm2, 261 psi): 2.82 – 3.03 V
A/C Refrigerant Pressure Sensor Removal and
Installation
S7RS0B7216013
Removal
1) Recover refrigerant from the A/C system with the recovery and recycling equipment referring to
“Recovery” in “Operation Procedure for Refrigerant
Charge”.
2) Disconnect negative (–) cable from battery.
3) Disconnect A/C refrigerant pressure sensor connector.
4) Remove A/C refrigerant pressure sensor (1) from liquid pipe (2).
Installation
Reverse removal procedure noting the following
instructions.
• Apply compressor oil to O-ring of A/C refrigerant
pressure sensor.
• Tighten A/C refrigerant pressure sensor to specified torque.
Tightening torque
A/C refrigerant pressure sensor (a): 11 N·m (1.1
kgf-m, 8.0 lb-ft)
• Evacuate and charge the A/C system referring to “Evacuation” and “Charge” in “Operation Procedure
for Refrigerant Charge”.
