CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
When the compressor is removed, store it in the sam e way at it is when mounted on the car. Failure
to do so will cause lubricant to enter the low-pressure chamber.
When connecting tubes, always use a to rque wrench and a back-up wrench.
After disconnecting tubes, immediately plug all op enings to prevent entry of dust and moisture.
When installing an air conditioner in the vehicle, connect the pipes at the final stage of the operation.
Never remove the seal caps of pipes and other compon ents until just before required for connection.
Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
Thoroughly remove moisture from the refriger ation system before charging the refrigerant.
Always replace used O-rings.
When connecting tubes, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
O-ring must be closely att ached to the groove of tube.
When replacing the O-ring, be careful not to damage O-ring and tube.
Connect tube until a click can be heard, then tighten the nut or bolt by hand. Make sure that the O-
ring is installed to tube correctly.
After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
Precaution for Service of CompressorINFOID:0000000001328156
Plug all openings to prevent moisture and foreign matter from entering.
When the compressor is removed, store it in th e same way at it is when mounted on the car.
When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compressor”
exactly. Refer to ATC-22, "
Maintenance of Lubricant Quantity in Compressor".
Keep friction surfaces between clut ch and pulley clean. If the surface is contaminated with lubricant,
wipe it off by using a clean w aste cloth moistened with thinner.
After compressor service operation, turn the compr essor shaft by hand more than five turns in both
directions. This will equally dist ribute lubricant inside the compressor. After the compressor is
installed, let the engine idle and operate the compressor for one hour.
After replacing the compressor magnet clutch, ap ply voltage to the new one and check for normal
operation.

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.

LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT
1. Before connecting recovery/recycling recharging equipm ent to vehicle, check recovery/recycling recharg-
ing equipment gauges. No refrigerant pressure should be displayed. If NG, recover refrigerant from equip-
ment lines.
2. Connect recovery/recycling recharging equipment to vehicle. Confirm refrigerant purity in supply tank
using recovery/recycling recharging equipment and refrigerant identifier. If NG, refer to AT C - 4 , "
Precaution
for Working with HFC-134a (R-134a)".
3. Confirm refrigerant purity in vehicle A/C system us ing recovery/recycling recharging equipment and refrig-
erant identifier. If NG, refer to AT C - 4 , "
Precaution for Working with HFC-134a (R-134a)".
4. Discharge refrigerant into the refrigerant recove ry/recycling equipment. Measure lubricant discharged into
the recovery/recycling equipment.
5. Drain the lubricant from the old (removed) comp ressor into a graduated container and recover the amount
of lubricant drained.
6. Drain the lubricant from the new compressor into a separate, clean container.
7. Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this
lubricant to new compressor through the suction port opening.
8. Measure an amount of new lubricant equal to the am ount recovered during discharging. Add this lubricant
to new compressor through the suction port opening.
9. If the liquid tank also needs to be replaced, add another 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant at
this time.
Do not add this 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant when replaces the compressor only.
