Checking for Refrigerant LeaksBJS000JF
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 electrical leak detector or fluorescent dye leak
detector (SST: J-42220).
If dye is observed, confirm the leak with an electrical 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 electrical 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.
CAUTION:
Moving the electrical 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 DetectorBJS000JG
1. Check A/C system for leaks using the UV lamp and safety goggles (SST: 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 open-
ing indicates an evaporator core assembly (tubes, core or expansion valve) 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 (SST: J-43872) to prevent future
misdiagnosis.
4. Perform a system performance check and verify the leak 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 InjectionBJS000JH
(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 (3.45 bar, 3.52 kg/cm
2 , 50
psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (SST: J-41459).
3. Connect the injector tool to the A/C low-pressure side service valve.
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 (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 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, 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.

CVT FLUIDPFP:KLE50
Checking CVT FluidBCS001FX
Fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to 176°F). The fluid level check pro-
cedure is as follows:
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20°C (68°F), it takes about 10
minutes for the CVT fluid to warm up to 50 to 80°C (122 to
176°F).
3. Park the vehicle on a level surface.
4. Apply parking brake firmly.
5. With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.
6. Pull out the CVT fluid level gauge from the CVT fluid charging
pipe after pressing the tab on the CVT fluid level gauge to
release the lock.
7. Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid
level gauge rotating 180° from the originally installed position,
then securely push the CVT fluid level gauge until it meets the
top end of the CVT fluid charging pipe.
CAUTION:
When wiping away the CVT fluid level gauge, always use
lint-free paper, not a cloth rag.
8. Place the selector lever in “P” or “N” and make sure the fluid
level is within the specified range.
CAUTION:
When reinstalling CVT fluid level gauge, insert it into the
CVT fluid charging pipe and rotate it to the original installa-
tion position until it is securely locked.

If CVT fluid is very dark or smells burned, check operation of
CVT. Flush cooling system after repair of CVT.

If CVT fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of CVT. Refer to CO-37,
"RADIATOR" .

2. Drain CVT fluid from CVT fluid cooler hose [outlet side (1)] and
refill with new CVT fluid at CVT fluid charging pipe with the
engine running at idle speed.
3. Refill until new CVT fluid comes out from CVT fluid cooler hose
[outlet side (1)].
About 30 to 50% extra fluid will be required for this procedure.
CAUTION:

Use only Genuine NISSAN CVT Fluid NS-2. Do not mix with other fluid.

Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.

When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.

Delete CVT fluid deterioration date with CONSULT-II after changing CVT fluid. Refer to CVT-46,
"Check CVT Fluid Deterioration Date" .
4. Check fluid leakage, fluid level and condition.
