Testing the refrigerant system for leaks is one of the most important phases of troubleshooting. One or more of the methods outlined will prove useful in detecting leaks or checking connections if service work is performed. Before beginning any leak test, attach a manifold gauge set and note pressure. If little or no pressure is indicated, a partial charge must be installed. Check all connections, compressor head gasket, oil filler plug and compressor shaft seal for leaks.
Electronic Leak Detectors
There are a number of electronic leak detectors, Fig. available to per...

Safety
The Freon refrigerant used in car air conditioners is also known as R-12. It is colorless and odorless both as a gas and a liquid. Since it boils (vaporizes) at -21.7°F, it will usually be in a vapor state when being handled in a repair shop. But if a portion of the liquid coolant should come in contact with the hands or face, note that its temperature momentarily will be at least 22° below zero.
Protective goggles should be worn when opening any refrigerant lines. If liquid coolant does touch the eyes, bathe the eyes quickly in cold water. Then apply a bland ...
