2. Disconnect the low-pressure flexible hose and high-pressure
pipe from the evaporator.
CAUTION:
Cap or wrap the joint of the low-pressure flexible hose and
the high-pressure pipe with a suitable tool such as a vinyl
tape to avoid the entry of air.
3. Remove the expansion valve cover.
4. Remove the expansion valve.
Removal and Installation for Desiccant AssemblyEJS000VI
REMOVAL
1. Remove the condenser.
2. Clean the area around the snap ring. Remove any dirt or rust.
CAUTION:
Be sure to clean carefully.
3. Remove the snap ring from the lower side of liquid tank.
4. Remove the cap, filter and desiccant assembly.
INSTALLATION
1. Install the new desiccant, filter, cap, O-ring, and snap ring.
2. The work must be performed with clean hands. (Gloves may
not be worn.)
3. The desiccant, filter, cap, O-ring, and snap ring cannot be
reused.
4. When inserting the desiccant, be sure to insert it all the way in,
taking care not to allow any dirt to contact the surrounding area.
5. Do not install the filter backwards.
6. When inserting the cap, be certain to avoid having the O-ring
catch on something, fall out, or contact dirt
7. Apply lubricating oil to the cap O-ring, then insert all the way to
the end.
8. Check that there is no dust or dirt adhering to the snap ring installation groove.
9. The snap ring must be installed securely into the groove.
Checking for Refrigerant LeaksEJS000VJ
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electronic refrigerant leak detector or fluorescent
dye leak detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.Expansion valve mounting bolts

Checking System for Leaks Using the Fluorescent Leak DetectorEJS000VK
1. Check A/C system for leaks using the UV lamp and safety glasses (J-42220) in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes, core or TXV) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (J-43872) to prevent future misdiag-
nosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
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 InjectionEJS000VL
(This procedure is only necessary when recharging the 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 (50 psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (J-41459).
3. Connect the injector tool to the A/C LOW PRESSURE side service fitting.
4. Start 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 injector tool J-41459 (refer to the manufacture's operat-
ing instructions).
6. With the engine still running, disconnect the injector tool from the service fitting.
CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system con-
nection and proceed with 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.
Electronic Refrigerant Leak DetectorEJS000VM
PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C leak detector
or equivalent. Ensure that the instrument is calibrated and set prop-
erly 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.
