COOLER PIPE AND HOSE
2. Remove bolt (A), and then disconnect low-pressure flexible
hose (1) from low-pressure pipe (2).
CAUTION:
To prevent the inclusion of foreign matter, use a cap or vinyl
tape to seal off the connection ports of the hose and pipe
from the atmosphere.
3. Remove bolt (A) and then disconnect low-pressure pipe (1) from expansion valve.
CAUTION:
To prevent the inclusion of foreign matter, use a cap or vinyl
tape to seal off the connection ports of the pipe and expan-
sion valve from the atmosphere.
4. Remove cowl top extension. Refer to
.
5. Move electric water pump 1 to secure work space. Refer to
6. Disconnect low-pressure pipe from the vehicle.
INSTALLATION
Note the following items, and then install in the reverse order of removal.
CAUTION:
• To prevent degradation in insulation performance, use special electric compressor oil as the com-
pressor oil.
• In order to prevent conventional PAG oil from becoming mixed in, never reuse recovered compres-
sor oil and instead always use new oil. The use of oil including the conventional PAG oil may
degrade the performance of insulation.
• To prevent performance degradation, never use a fluorescent agent in order to detect refrigerant
leakage. Also be careful that a fluorescent agent never enter the oil.
• To prevent leakage of refrigerant, replace the O-ring with a new one. Apply a coat of compressor oil
to the O-ring prior to installation.
• Perform a check for refrigerant leakage when charging with refrigerant. Refer to
.

DANGER:
Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of
electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are
handled incorrectly. Be sure to follow the correct work procedures when performing inspection and
maintenance.
WARNING:
• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-
ing inspection or maintenance of high voltage system harnesses and parts.
• The removed service plug must always be carried in a pocket of the responsible worker or placed in
the tool box during the procedure to prevent the plug from being connected by mistake.
• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses
before beginning work on the high voltage system.
• Never allow workers other than the responsible person to touch the vehicle containing high voltage
parts. To keep others from touching the high voltage parts, these parts must be covered with an insu-
lating sheet except when using them. Refer to
GI-34, "High Voltage Precautions"

CAUTION:
Never bring the vehicle into the READY status with the service plug removed unless otherwise
instructed in the Service Manual. A malfunction may occur if this is not observed.
REMOVAL
1. Use the refrigerant recovery equipment (for HFC134a) and recover the refrigerant. Refer to
2. Remove radiator upper grille. Refer to
DLK-165, "RADIATOR UPPER GRILLE : Removal and Installa-
3. Remove washer tank inlet. Refer to
4. Remove bolt (A), and then disconnect high-pressure flexible
hose (1) and high-pressure pipe (2) from condenser.
CAUTION:
To prevent the inclusion of foreign matter, use a cap or vinyl
tape to seal off the connection ports of the pipe and con-
denser from the atmosphere.
5. Remove charge port bracket. Refer to
.
6. Remove radiator core support lower stay. Refer to
DLK-163, "RADIATOR CORE SUPPORT LOWER :
.
7. Remove radiator core support upper. Refer to
DLK-161, "RADIATOR CORE SUPPORT UPPER :
.
8. Disconnect refrigerant pressure sensor connector (A).

9. Lift the condenser upwards while pressing the tabs (1) on the right and left of the radiator to remove con-
denser.
INSTALLATION
Note the following items, and then install in the reverse order of removal.
CAUTION:
• When installing the condenser, securely insert the mating part indicated by the arrow in the diagram.
• To prevent degradation in insulation performance, use special electric compressor oil as the com-
pressor oil.
• In order to prevent conventional PAG oil from becoming mixed in, never reuse recovered compres-
sor oil and instead always use new oil. The use of oil including the conventional PAG oil may
degrade the performance of insulation.
• To prevent performance degradation, never use a fluorescent agent in order to detect refrigerant
leakage. Also be careful that a fluorescent agent never enter the oil.
• After installing a new condenser, adjust the compressor oil level. Refer to
ing Procedure for Components Replacement Except Compressor"
• To prevent leakage of refrigerant, replace the O-ring with a new one. Apply a coat of compressor oil
to the O-ring prior to installation.
• Perform a check for refrigerant leakage when charging with refrigerant. Refer to
.
