5) Warm up engine to the normal operating temperature and keep it at the specified idle speed.
6) Turn A/C switch ON, set blower speed selector at maximum speed position, temperature selector at
maximum cold position, airflow selector at face
position, and air intake switch at recirculation
position. (Confirm that A/C compressor and
condenser fans are working.)
7) Wait for ten minutes to stabilize the A/C operation.
8) Open front windows, front doors and engine hood.
9) With about 20 mm (0.8 in.) of dry bulb thermometer
(1) put right in front of center ventilation louver and a
wet and dry bulb thermometer (2) near air inlet of
HVAC unit. 10) Check for each pressure of low side and high side if
it is within shaded range of graph. If each gauge
reading is out of specified pressure, correct defective
part referring to the following table.
NOTE
Pressure registered on gauge varies with
ambient temperature. Therefore, use the
graphs when determining if pressures are
normal or not.
Low side and high side pressure example,
Gauges should read as follows when ambient
temperature is 30 °C (86 °F)
Pressure on high pressure gauge (HI): 1590 –
1940 kPa (15.9 – 19.4 kg/cm2)
Pressure on low pressure gauge (LO): 270 – 430

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).

Receiver/Dryer Removal and InstallationS7RS0B7216031
Removal
1) Remove front bumper referring to “Front Bumper and Rear Bumper Components in Section 9K”.
2) Remove receiver/dryer bolt (1), and then remove receiver/dryer (2) from condenser.
3) Remove joints (3) and O-rings (4). Installation
Reverse the removal procedure noting the following
instructions.
• Replenish specified amount of compressor oil to
compressor suction side referring to “When replacing
other parts” in “Operation Procedure for Refrigerant
Charge”.
• Use new receiver/dryer and O-ring.
• Do not remove plug from receiver/dryer until just before installin g it condenser.
• Apply compressor oil to O-ring.
