Is there any way to check the micro-leaks of the evaporator and the condenser?
R134a compatibility is poor, because the leak is difficult to find oil traces, fluorescent leak detector also lost its useful.
1, fluorescence leak detection is the use of fluorescent leak detector in the UV / blue light leaks and other exposure will be issued a bright yellow-green light principle, the leakage of various types of systems to detect, but R134a application of the initial use of PAG lubricants and
Check the leak is the primary work of leakage maintenance, commonly used means of leak detection leak detection, soapy water leak detection, halogen leak detection, electronic leak detection.
2, soapy water leak is charged to the system pressure 0.98-1.96Mpa nitrogen, and then coated with soap and water in all parts of the system, bubbling is the point of leakage, this method is the roadside repair shop recently
