CHECKING REFRIGERANT LEAKS=NLHA0168Preliminary CheckNLHA0168S01Perform a visual inspection of all refrigeration parts, fittings, hoses,
and components for signs of A/C lubricant leakage, damage and
corrosion. Take note of the areas with A/C lubricant leakage to
allow extra time in these areas with electronic leak detector.
SHA705EB
Precautions for Handling Leak DetectorNLHA0168S02When performing a refrigerant leak check, use an A/C leak detec-
tor 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.
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 detec-
tor.
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.

SHA708EA
3. Move probe along component approximately 25 to 50 mm (1
to 2 in)/sec.
Checking ProcedureNLHA0168S03To 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 345.2 kPa (3.45
bar, 3.52 kg/cm
2, 50.1 psi) above 16°C (61°F). If less than
specification, recover/evacuate and recharge the system with
the specified amount of refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected
since the system may not reach 345.2 kPa (3.45 bar, 3.52 kg/cm
2,
50.1 psi).
4. Conduct the leak test from the high side (compressor dis-
chargeato evaporator inletg) to the low side (evaporator drain
hosehto shaft sealk). Refer to HA-98. 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.
+Compressor
Check the fitting of high and low pressure hoses, relief valve
and shaft seal.
+Liquid tank
Check the pressure switch, refrigerant pressure sensor, tube
fitting, weld seams and the fusible plug mount.
+Service 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.
+Cooling unit (Evaporator)
With engine OFF, turn blower fan on“High”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.
SERVICE PROCEDURE

HA-101

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 position
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. Discharge A/C system using approved refrigerant recovery
equipment. Repair the leaking fitting or component as neces-
sary.
12. Evacuate and recharge A/C system and perform the leak test
to confirm no refrigerant leaks.
13. Conduct A/C performance test to ensure system works
properly.
