automotive air conditioning refrigerant leakage seven simple detection method(1)

Sensor
In summer, Auto Diagnostic Tool the refrigerant leakage is the most common use of air conditioning failure. Some refrigerant a year to add time, some might add two. The refrigerant leak is likely to cause environmental pollution, in addition to increasing the cost and time of the maintenance vehicle owners. Seven of automotive air conditioning leak detection method.

Automotive Car OBD2 Tools supplier air conditioning refrigerant leakage
Visual leak detection
Found somewhere in the system there are traces of oil, where possible leakage points. Visual leak detection is simple, there is no cost, but there is a great defect, unless OBD2 diagnostic tools China the system is suddenly fracture leakage point, and the system leak liquid colored media or visual leak detection can not locate, because usually very subtle leakage and automotive air conditioning could barely see a lot of parts.
  
Soapy water leak detection
Filled a 10-20kgcm2 pressure nitrogen to the system, coated with soap and water in various parts of the system, is bubbling at is the leakage point. This approach is currently the most common roadside repair shop leak detection methods, but the man's arm is limited, human vision is limited in ベンツ専用診断機 scope, often do not see the leak.
