2. Check oil level.
CAUTION:
Do not reuse gasket.
Checking A/T FluidELS001JZ
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Loosen level gauge bolt.
4. Before driving, A/T fluid level can be checked at A/T fluid tem-
peraturesof30to50°C(86to122°F) using “COLD” range on A/
T fluid level gauge as follows.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free
paper.
CAUTION:
When wiping away A/T fluid level gauge, always use lint-
free paper, not a cloth one.
e. Reinsert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
CAUTION:
To check A/T fluid level, insert A/T fluid level gauge until the cap contacts the end of A/T fluid
charging pipe, with A/T fluid level gauge reversed from the normal attachment conditions.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add ATF to A/T fluid
charging pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. Make the A/T fluid temperature approximately 65°C(149°F). Oil grade and
viscosity:Refer toMA-14, "
Fluids and Lubri-
cants".

CHASSIS AND BODY MAINTENANCE
NOTE:
A/T fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to
perform operation while checking data with CONSULT-II.
a. Connect CONSULT-II to data link connector. Refer toAT-79, "
CONSULT-II SETTING PROCEDURE".
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Readthevalueof“ATFTEMP1”.
7. Recheck A/T fluid level at A/T fluid temperatures of approximately 65°C(149°F)using“HOT”rangeonA/
T fluid level gauge.
CAUTION:
lWhen wiping away A/T fluid level gauge, always use lint-free paper, not a cloth one.
lTo check A/T fluid level, insert A/T fluid level gauge until
the cap contacts the end of A/T fluid charging pipe, with
A/T fluid level gauge reversed from the normal attach-
ment conditions as shown.
8. Check A/T fluid condition.
lIf ATF is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.
lIf A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer toCO-11,
"RADIATOR".
9. Install the removed A/T fluid level gauge into A/T fluid charging
pipe.
10. Tighten level gauge bolt to the specified torque. Refer toAT-247,

Changing A/T FluidELS001K0
1. Warm up ATF.
2. Stop engine.
3. Loosen level gauge bolt.
4. Remove A/T fluid level gauge.
5. Remove drain plug and drain ATF from drain hole.
6. Install drain plug gasket and drain plug to oil pan.
CAUTION:
Do not reuse drain plug gasket.
7. Tighten drain plug to the specified torque. Refer toAT-218,
"COMPONENTS".
8. Refill with new ATF. Always refill same volume with drained ATF.
lTo replace the ATF, pour in new ATF at A/T fluid charging pipe
with the engine idling and at the same time drain the old ATF
from A/T fluid cooler hose return side.
lWhen the color of the ATF coming out is about the same as the color of the new ATF, the replacement
is complete. The amount of new ATF to use should be 30 to 50% increase of the specified amount.
CAUTION:
lUse only Genuine NISSAN ATF Matic Fluid J. Do not mix with other ATF.
lUsing ATF other than Genuine NISSAN ATF Matic Fluid J will cause deterioration in driveability
and A/T durability, and may damage the A/T, which is not covered by the NISSAN new vehicle
warranty.
lWhen filling ATF, take care not to spillover heat generating parts such as exhaust.
9. Run engine at idle speed for 5 minutes.
10. Check A/T fluid level and condition. Refer toMA-29, "
Checking A/T Fluid". If ATF is still dirty, repeat step
2 through 9.
11. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
12. Tighten level gauge bolt to the specified torque. Refer toAT- 2 4 7 , "
COMPONENTS".
Checking Transfer FluidELS001IQ
FLUID LEAKAGE AND FLUID LEVEL
1. Make sure that fluid is not leaking from the transfer assembly or around it.
2. Check fluid level from the filler plug hole as shown.
CAUTION:
Do not start engine while checking fluid level.
3. Install the filler plug with a new gasket to the transfer. Tighten to
the specified torque. Refer toTF-112, "
COMPONENTS".

O-Ring Part Numbers and Specifications
*: Always check with the Parts Department for the latest parts information.
WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
lWhen the compressor is removed, store it in the same position as it is when mounted on the car.
Failure to do so will cause lubricant to enter the low pressure chamber.
lWhen connecting tubes, always use a torque wrench and a back-up wrench.
lAfter disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
lWhen installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.
lAllow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
lThoroughly remove moisture from the refrigeration system before charging the refrigerant.
lAlways replace used O-rings.
lWhen connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
Lubricant name: NISSAN A/C System Lubricant Type S (DH-PS) or equivalent
Part number: KLH00-PAGS0
lO-ring must be closely attached to dented portion of tube.
lWhen replacing the O-ring, be careful not to damage O-ring and tube.
lConnect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.

PRECAUTIONS
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to an
CFC-12 (R-12) A/C system. The 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 1/2²-16
ACME.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:
1. Press “Shift/Reset”and“Enter”at the same time.
2. Press “8787”.“A1” will be displayed.
3. Remove all weight from the scale.
4. Press “0”, then press “Enter”.“0.00” will be displayed and change to “A2”.
5. Place a known weight (dumbbell or similar weight), between 4.5 and 8.6 kg (10 and 19 lb.) on the center
of the weight scale.
6. Enter the known weight using four digits. (Example 10 lb. = 10.00, 10.5 lb. = 10.50)
7. Press “Enter”— the display returns to the vacuum mode.
8. Press“Shift/Reset”and“Enter”at the same time.
9. Press “6” — the known weight on the scale is displayed.
10. Remove the known weight from the scale. “0.00” will be displayed.
11. Press“Shift/Reset” to return the ACR4 to the program mode.
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 accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precautions for Leak Detection DyeEJS0062B
lThe A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
lAlways wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
lThe fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector (J-
41995) to pin-point refrigerant leaks.
lFor your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.
