Kia Sedona (2008 year). Manual - part 38

3. If the low-pressure does not reach more than 93.3 kPa (700 mmHg, 27.6 in.Hg) in 10 minutes, there is 

probably a leak in the system. Partially charge the system, and check for leaks. See REFRIGERANT 
LEAK TEST.  

4. Remove the low pressure valve from the low-pressure service port.  

SYSTEM CHARGING 

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. 

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

1. Connect an R-134a refrigerant Recovery/Recycling/Charging System (A) to the high-pressure service 

port (B) as shown in Fig. 8, following the equipment manufacturer's instructions.

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

specified refrigerant oil. Charge the system with 18.0 ± 0.88 oz. (510 ± 25g) of R-134a refrigerant. Do not 
overcharge the system the compressor will be damaged.

Always conduct a leak test with an electronic leak detector whenever leakage or refrigerant is suspected and 
when conducting service operations which are accompanied by disassembly or loosening or connection fittings. 

If a gas leak is detected, proceed as follows: 

1. Check the torque on the connection fittings and, if too loose, tighten to the proper torque. Check for gas 

leakage with a leak detector (A).  

2. If leakage continues even after the fitting has been tightened, discharge the refrigerant from the system, 

disconnect the fittings, and check their seating faces for damage. Always replace, even if the damage is 
slight.  

3. Check the compressor oil and add oil if required.  

4. Charge the system and recheck for gas leaks. If no leaks are found, evacuate and charge the system again.
