Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. T he HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2
″-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accura cy of the cylinder is generally less than that of an
electrical scale or of quality recycle/recharge equipment.
Precaution for Leak Detection DyeINFOID:0000000001328158
 The A/C system contains a fluorescent leak detection dy e used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
 Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
 The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST: J-41995). The flu-
orescent dye leak detector should be used in conjunc tion with an electrical leak detector (SST: J-41995) to
pin-point refrigerant leaks.
 For the purpose of safety and customer’s satisfacti on, read and follow all manufacture’s operating instruc-
tions and precautions prior to performing the work.
 A compressor shaft seal should not necessarily be re paired because of dye seepage. The compressor shaft
seal should only be repaired after confirming the l eak with an electrical leak detector (SST: J-41995).
 Always remove any remaining dye from the leak area after repairs are completed to avoid a misdiagnosis during a future service.
 Never allow dye to come into contact with painted body panels or interior components. If dye is spilled, clean
immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period of time
cannot be removed.
 Never spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
 Never use more than one refrigerant dye bot tle (1/4 ounce /7.4 cc) per A/C system.
 Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Never use HFC-
134a (R-134a) leak detection dye in CFC-12 (R-12) A/ C system, or CFC-12 (R-12) leak detection dye in
HFC-134a (R-134a) A/C system, or A/C system damage may result.
 The fluorescent properties of the dye will remain for thr ee years or a little over unless a compressor malfunc-
tion occurs.
IDENTIFICATION
NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.

PREPARATION
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CF C-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Never use adapters that convert one size fitting to another: refrigerant/lubricant contamination occurs and
compressor malfunction may result.

4. Perform a system performance check and verify the l eak repair with an approved electrical leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.
Dye InjectionINFOID:0000000001328233
(This procedure is only necessary when recharging t he system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.52 kg/cm
2, 50 psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refr igerant dye into the injector tool (SST: J-41459).
3. Connect the injector tool to the A/C low-pressure side service valve.
4. Start the engine and switch A/C ON.
5. When the A/C operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye
through the low-pressure service valve using dye inje ctor tool (SST: J-41459) (refer to the manufacture’s
operating instructions).
6. With the engine still running, disconnect the injector tool from the service valve. CAUTION:
Be careful the A/C system or replacing a componen t, pour the dye directly into the open system
connection and proceed wi th the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leak size, operating conditions and location of the leak , it may take from minutes to days for the dye to
penetrate a leak and become visible.
8. Attach a blue label as necessary.
Electrical Leak DetectorINFOID:0000000001328234
PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C electrical leak
detector (SST) or equivalent. Ensure that the instrument is calibrated
and set properly per the operating instructions.
The leak detector is a delicate device. In order to use the leak detec-
tor properly, read the operating instructions and perform any speci-
fied maintenance.
1. Position probe approximately 5 mm (3/16 in) away from point to
be checked.
