CHECKING FOR REFRIGERANT LEAKS=NBHA0078IPerform 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.
IIf dye is observed, confirm the leak with an electronic refriger-
ant leak detector. It is possible a prior leak was repaired and
not properly cleaned.
IWhen searching for leaks, do not stop when one leak is found
but continue to check for additional leaks at all system compo-
nents and connections.
IWhen 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.
NOTE:
Moving the electronic leak detector probe slower and closer to
the suspected leak area will improve the chances of finding a
leak.
CHECKING SYSTEM FOR LEAKS USING THE
FLUORESCENT LEAK DETECTOR
NBHA01161. 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 indicates an evaporator core assembly (tubes, core or
TXV) leak.
2. If the suspected area is difficult to see, use an adjustable mir-
ror or wipe the area with a clean shop rag or cloth, then check
the 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 misdiagnosis.
4. Perform a system performance check and verify the leak repair
with an approved electronic refrigerant leak detector.
NOTE:
IOther 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.
IDo 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 INJECTIONNBHA0117(This procedure is only necessary when re-charging 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 operating instructions).
6. With the engine still running, disconnect the injector tool from
the service fitting.
CAUTION:
Be careful not to allow dye to spray or drip when disconnect-
ing the injector from the system.
NOTE:
If repairing the A/C system or replacing a component, pour the
dye directly into the open system connection 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, oper-
ating conditions and location of the leak, it may take from min-
utes to days for the dye to penetrate a leak and become visible.
SHA196FA
ELECTRONIC REFRIGERANT LEAK DETECTORNBHA0115Precautions for Handling Leak DetectorNBHA0115S01When performing a refrigerant leak check, use a J-41995 A/C leak
detector 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
detector properly, read the operating instructions and perform any
specified maintenance.
SHA707EA
1. Position probe approximately 5 mm (3/16 in) away from point
to be checked.
SHA706E
2. When testing, circle each fitting completely with probe.
SERVICE PROCEDURE
Refrigerant Lines (Cont'd)
HA-156

SHA708EA
3. Move probe along component approximately 25 to 50 mm (1
to 2 in)/sec.
Checking ProcedureNBHA0115S02To prevent inaccurate or false readings, make sure there is no
refrigerant vapor, shop chemicals, or cigarette smoke in the
vicinity of the vehicle. Perform the leak test in calm area (low
air/wind movement) so that the leaking refrigerant is not dis-
persed.
1. Turn engine off.
2. Connect a suitable A/C manifold gauge set to the A/C service
ports.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.52
kg/cm
2, 50 psi) above 16ÉC (61ÉF). If less than specification,
recover/evacuate and recharge the system with the specified
amount of refrigerant.
NOTE:
At temperatures below 16ÉC (61ÉF), leaks may not be detected
since the system may not reach 345 kPa (3.52 kg/cm
2, 50 psi).
4. Conduct the leak test from the high side (compressor dis-
chargeato evaporator inletf) to the low side (evaporator drain
hosegto shaft sealk). Refer to HA-154. Perform a leak check
for the following areas carefully. Clean the component to be
checked and move the leak detector probe completely around
the connection/component.
ICompressor
Check the fitting of high and low pressure hoses, relief valve
and shaft seal.
ILiquid tank
Check the pressure switch, tube fitting, weld seams and the
fusible plug mount.
IService valves
Check all around the service valves. Ensure service valve caps
are secured on the service valves (to prevent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe
any residue from valves to prevent any false readings by leak
detector.
ICooling unit (Evaporator)
With engine OFF, turn blower fan on ªHighº for at least 15
seconds to dissipate any refrigerant trace in the cooling unit.
Wait a minimum of 10 minutes accumulation time (refer to the
manufacturer's recommended procedure for actual wait time)
before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least ten seconds. Use caution
not to contaminate the ptobe tip with water or dirt that may be
in the drain hose.

5. If a leak detector detects a leak, verify at least once by blow-
ing compressed air into area of suspected leak, then repeat
check as outlined above.
6. Do not stop when one leak is found. Continue to check for
additional leaks at all system components.
If no leaks are found, perform steps7-10.
7. Start engine.
8. Set the heater A/C control as follows:
1) A/C switch ON.
2) Face mode
3) Recirculation switch ON
4) Max cold temperature
5) Fan speed high
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps
4 through 6 above.
SHA839E
Refrigerant leaks should be checked immediately after
stopping the engine. Begin with the leak detector at the
compressor. The pressure on the high pressure side will
gradually drop after refrigerant circulation stops and pres-
sure on the low pressure side will gradually rise, as shown
in the graph. Some leaks are more easily detected when
pressure is high.
11. Before connecting ACR4 to vehicle, check ACR4 gauges. No
refrigerant pressure should be displayed. If pressure is
displayed, recover refrigerant from equipment lines and then
check refrigerant purity.
12. Confirm refrigerant purity in supply tank using ACR4 and refrig-
erant identifier.
13. Confirm refrigerant purity in vehicle A/C system using ACR4
and refrigerant identifier.
14. Discharge A/C system using approved refrigerant recovery
equipment. Repair the leaking fitting or component as neces-
sary.
15. Evacuate and recharge A/C system and perform the leak test
to confirm no refrigerant leaks.
16. Conduct A/C performance test to ensure system works
properly.
