Leak Testing

Print

Specific to:

Honda CR-V 2007-2008


CAUTION
Before beginning this procedure, refer to the Precautions at the beginning of this section. Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components. Failure to follow the warnings and cautions could result in possible personal injury or death.

Always conduct a leak test with an electronic leak detector whenever leakage of refrigerant is suspected and when conducting service operations which are accompanied by disassembly or loosening of connection fittings. This procedure requires the use of Leak detector, Honda Tool and Equipment YGK-H-10PM commercially available, or an equivalent leak detector.


NOTE
In order to use the leak detector properly, read the manual supplied by the manufacturer.

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 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.
  2.  
  3. 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.
  4.  
  5. If oil has been removed from the system, oil if required.
  6.  
  7. Charge the system and recheck for gas leaks.
  8.  
  9. Check the system for leaks using an R-134a refrigerant leak detector with an accuracy of reading 0.5 oz (14 g) per year or better.
  10.  
  11. If you find leaks that require the system to be opened (to repair or replace hoses, fittings, etc.), recover the system.
  12.  
  13. After checking and repairing leaks, the system must be evacuated.
