11. Install the A/C condenser in the reverse order of removal, and note these items: 



If you're installing a new A/C condenser, add refrigerant oil (DENSO ND-OIL 8) (see A/C 
SERVICE TIPS AND PRECAUTIONS ).  



Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before 
installing them. Be sure to use the correct O-rings for HFC-134a (R-134a) to avoid leakage.  



Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture 
absorption.  



Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil 
contacts the paint, wash it off immediately.  



Charge the system (see SYSTEM CHARGING ).  



Reset the power window control unit (see RESETTING THE POWER WINDOW 
CONTROL UNIT ).  



Do the steering column position memorization (see STEERING COLUMN POSITION 
MEMORIZATION ).  



Enter the anti-theft codes for the audio system and the navigation system (if equipped).  



Set the clock.  

RECEIVER/DRYER DESICCANT REPLACEMENT 

1. Remove the A/C condenser (see A/C CONDENSER REPLACEMENT ).  

2. Remove the cap (A) from the bottom of the A/C condenser. Remove the O-ring (B) and the desiccant 

(C). 

NOTE:

Install the receiver/dryer as quickly as possible to prevent the system from 
absorbing moisture from the air.

3. Install the receiver/dryer in the reverse order of removal, and note these items: 



Replace the O-rings with new ones, and apply a thin coat of refrigerant oil (DENSO ND-OIL 8) 
before installing them. Be sure to use the correct O-rings for HFC-134a (R-134a) to avoid 
leakage.  



Install the cap to the specified torque. It is made of resin and can be easily stripped.  

REFRIGERANT RECOVERY 

1. Connect an R-134a refrigerant recovery/recycling/ charging station (A) to the high-pressure service 

port (B) and the low-pressure service port (C), as shown, following the equipment manufacturer's 
instructions. 

CAUTION:



Air conditioning refrigerant or lubricant vapor can irritate your 
eyes, nose, or throat.  



Be careful when connecting service equipment.  



Do not breathe refrigerant or vapor.  

NOTE:



If accidental system discharge occurs, ventilate the work area before 
resuming service.  



Additional health and safety information may be obtained from the 
refrigerant and lubricant manufacturers.

2. Measure the amount of refrigerant oil removed from the A/C system after the recovery process is 

completed. Be sure to put the same amount of new refrigerant oil back into the A/C system before 
charging.  

SYSTEM EVACUATION 

1. When an A/C System has been opened to the atmosphere, such as during installation or repair, it must 

be evacuated using an R-134a refrigerant recovery/recycling/charging station. If the system has been 
open for several days, the receiver/dryer should be replaced, and the system should be evacuated for 
several hours.  

2. Connect an R-134a refrigerant recovery/recycling/ charging station (A) to the high-pressure service 

port (B) and the low-pressure service port (C), as shown, following the equipment manufacturer's 
instructions. Evacuate the system. 

CAUTION:



Air conditioning refrigerant or lubricant vapor can irritate your 
eyes, nose, or throat.  



Be careful when connecting service equipment.  



Do not breathe refrigerant or vapor.  

NOTE:



If accidental system discharge occurs, ventilate the work area before 
resuming service.  



Additional health and safety information may be obtained from the 
refrigerant and lubricant manufacturers.

3. If the low-pressure does not reach more than 93.3 kPa (700 mmHg, 27.6 in.Hg) in 15 minutes, there is 

probably a leak in the system. Partially charge the system, and check for leaks (see step 3 ).  

SYSTEM CHARGING 

1. Connect an R-134a refrigerant recovery/recycling/ charging station (A) to the high-pressure service 

port (B) and the low-pressure service port (C), as shown, following the equipment manufacturer's 
instructions. 

CAUTION:



Air conditioning refrigerant or lubricant vapor can irritate your 
eyes, nose, or throat.  



Be careful when connecting service equipment.  



Do not breathe refrigerant or vapor.  

NOTE:



If accidental system discharge occurs, ventilate the work area before 
resuming service.  



Additional health and safety information may be obtained from the 
refrigerant and lubricant manufacturers.
