CVT FLUID : Inspection
CHECKING CVT FLUID
The fluid level should be checked with the fluid warmed up to 50 to 80C
(122 to 176F). The fluid level
check procedure is as follows:
- Check for fluid leakage.
- With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20C (68F), it takes about 10
minutes for the CVT fluid to warm up to 50 to 80C (122 to
176F).
- Park the vehicle on a level surface.
- Apply parking brake firmly.
- With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.
- 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.
- 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.
- Place the shift selector in "P" or "N" position and check that 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 installation
position until securely locked.
CVT FLUID CONDITION
Check CVT fluid condition.
CVT FLUID : Changing
CAUTION: Replace a O-ring with new ones at the final stage
of the operation when installing.
- Remove drain plug from oil pan.
- Remove O-ring from drain plug and discard the O-ring.
- Install a new O-ring on drain plug.
CAUTION:
Do not reuse O-ring.
- Install drain plug in oil pan. Refer to TM-177, "Exploded View".
- Fill CVT fluid from CVT fluid charging pipe to the specified
level.
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.
- Sufficiently shake the container of CVT fluid before using.
- Delete CVT fluid deterioration date with CONSULT after changing
CVT fluid. Refer to TM-38,
"CONSULT Function".
- With the engine warmed up, drive the vehicle in an urban area.
NOTE:
When ambient temperature is 20C (68F), it takes about 10 minutes for the
CVT fluid to warm up to 50
to 80C (122 to 176F).
- Check CVT fluid level and condition.
- Repeat steps 1 to 5 if CVT fluid has been contaminated.
WHEELS
WHEELS : Inspection
ALUMINUM WHEEL
- Check tires for wear and improper inflation.
- Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel
runout.
- Remove tire from aluminum wheel and then mount
the wheel on a tire balancer machine. Remove the
transmitter, refer to WT-59, "Removal and Installation".
- Set dial indicator as shown and rotate the wheel to check
for
runout.
- Replace wheel if runout exceeds specification.
WHEELS : Adjustment
BALANCING WHEELS (ADHESIVE WEIGHT TYPE)
Preparation Before Adjustment
Remove inner and outer balance weights from the road wheel using releasing
agent, remove double-faced
adhesive tape from the road wheel.
CAUTION:
- Be careful not to scratch the road wheel during removal.
- After removing double-faced adhesive tape, wipe clean all traces of
releasing agent from the road
wheel.
Wheel Balance Adjustment
- Set road wheel on balancer machine using the center hole as a
guide. Start the balancer machine.
- For balancer machines that only have a clip-on (rim flange) weight
mode setting, follow this step to calculate
the correct size adhesive weight to use. When inner and outer imbalance
values are shown on the
balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to
determine balance weight that
should be used. Select the outer balance weight with a value closest to the
calculated value above and
install in to the designated outer position of, or at the designated angle
in relation to the road wheel.
- Indicated imbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 (1.67) = 38.33 g (1.35 oz) ⇒ 40 g (1.41 oz)
balance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 ⇒ 35 g (1.23 oz)
37.5 ⇒ 40 g (1.41 oz)
- Install balance weight in the position shown.
CAUTION:
- Do not install the inner balance weight before installing
the outer balance weight.
- Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
- When installing balance weight (1) to road wheel, set it into
the
grooved area (A) on the inner wall of the road wheel as shown
so that the balance weight center (B) is aligned with the balancer
machine indication position (angle) (C).
CAUTION:
- Always use Genuine NISSAN adhesive balance weights.
- Balance weights are non-reusable; always replace with
new ones.
- Do not install more than three sheets of balance weight.
- If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other as shown.
CAUTION:
Do not install one balance weight sheet on top another.
- Start balancer machine again.
- Install balance weight on inner side of road wheel in the balancer
machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
- Start balancer machine. Make sure that inner and outer residual
imbalance values are 5 g (0.17 oz) each
or below.
- If either residual imbalance value exceeds 5 g (0.17 oz), repeat
installation procedures.
TIRE ROTATION
CAUTION:
- Do not include the T-type spare tire when rotating the tires.
- When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
- Be careful not to tighten wheel nut at torque exceeding the
criteria for preventing strain of disc rotor.
