Acura TSX / Honda Accord CL. Manual - part 687

2. Evacuate the system (see SYSTEM EVACUATION ).  

3. Add the same amount of new refrigerant oil to the system that was removed during recovery. Use only 

DENSO ND-OIL 8 refrigerant oil.  

4. Charge the system with the specified amount of R-134a refrigerant. Do not overcharge the system; the 

compressor will be damaged. Select the appropriate units of measure for your refrigerant charging station. 

Refrigerant Capacity: 500 to 550 g (0.50 to 0.55 kg; 1.1 to 1.2 lbs; 17.6 to 19.4 oz.)  

5. Check for refrigerant leaks (see REFRIGERANT LEAK TEST ).  

6. Check for system performance (see PERFORMANCE TEST ).  

REFRIGERANT LEAK TEST 

Special Tool Required: Leak detector, Honda Tool and Equipment YGK-H-10PM commercially available 

Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove 
HFC-134a (R-134a) from the air conditioning system. 

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

R-134a service equipment or vehicle air conditioning systems should not be pressure tested or leak tested with 
compressed air. 

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

1. Connect a 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. 

WARNING:

z

Compressed air mixed with R-134a forms a combustible vapor.  

z

The vapor can burn or explode causing serious injury.  

z

Never use compressed air to pressure test R-134a service 
equipment or vehicle air conditioning system.  

CAUTION:

z

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

z

Be careful when connecting service equipment.  

z

Do not breathe refrigerant or vapor.

2. Open high pressure valve to charge the system to the specified capacity, then close the supply valve, and 

disconnect the charging station fittings. Select the appropriate units of measure for your refrigerant 
charging station. 

Refrigerant Capacity: 500 to 550 g (0.50 to 0.55 kg; 1.1 to 1.2 lbs; 17.6 to 19.4 oz.)  

3. Check the system for leaks using a R-134a refrigerant leak detector with an accuracy of 14 g (0.5 oz.) per 

year or better.  

4. If you find leaks that require the system to be opened (to repair or replace hoses, fittings, etc.), recover the 

system.  

5. After checking and repairing leaks, the system must be evacuated.  

A/C SYSTEM TEST 

PERFORMANCE TEST 

The performance test will help determine if the air conditioner system is operating within specifications. 

Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove 
HFC-134a (R-134a) from the air conditioning system. 

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

R-134a service equipment or vehicle air conditioning systems should not be pressure tested or leak tested with 
compressed air. 

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

1. Connect a R-134a refrigerant recovery/recycling/charging station to the high-pressure service port and the 

low-pressure service port, following the equipment manufacturer's instructions.  

2. Determine the relative humidity and air temperature.  

3. Open the glove box. Remove the damper from the glove box, then let the glove box hang down (see 

GLOVE BOX REMOVAL/INSTALLATION ).  

4. Insert a thermometer (A) in the center vent. 

WARNING:

z

Compressed air mixed with R-134a forms a combustible vapor.  

z

The vapor can burn or explode causing serious injury.  

z

Never use compressed air to pressure test R-134a service 
equipment or vehicle air conditioning systems.  

CAUTION:

z

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

z

Be careful when connecting service equipment.  

z

Do not breathe refrigerant or vapor.
