12. Remove idler pulley and bracket. Refer to EM-173, "
TIMING CHAIN" .
13. Remove timing chain tensioner (primary) as follows:
a. Remove lower mounting bolt.
b. Loosen upper mounting bolt slowly, and then turn timing chain
tensioner (primary) on the mounting bolt so that plunger is fully
expanded.
NOTE:
Even if plunger is fully expanded, it is not dropped from the body
of timing chain tensioner (primary).
c. Remove upper mounting bolt, and then remove timing chain ten-
sioner (primary).
CAUTION:
Be careful not to drop mounting bolts inside timing chain
case.
14. Remove water pump as follows:
a. Remove three water pump mounting bolts. Secure a gap
between water pump gear and timing chain, by turning crank-
shaft pulley counterclockwise until timing chain looseness on
water pump sprocket becomes maximum.
b. Screw M8 bolts [pitch: 1.25 mm (0.049 in) length: Approx. 50
mm (1.97 in)] into water pumps upper and lower mounting bolt
holes until they reach timing chain case. Then, alternately
tighten each bolt for a half turn, and pull out water pump.
CAUTION:

Pull straight out while preventing vane from contacting
socket in installation area.

Remove water pump without causing sprocket to contact
timing chain.
c. Remove M8 bolts and O-rings from water pump.
CAUTION:
Do not disassemble water pump.
INSPECTION AFTER REMOVAL

Check for badly rusted or corroded water pump body assembly.

e. Install timing chain tensioner (primary).

Remove any dirt and foreign materials completely from the
back and the mounting surfaces of timing chain tensioner (pri-
mary).
f. Pull out stopper pin after installing, and then release plunger.
g. Make sure again that timing chain and water pump sprocket are
engaged.
4. Install chain tensioner cover and water pump cover as follows:
a. Before installing, remove all traces of old liquid gasket from mat-
ing surface of water pump cover and chain tensioner cover
using scraper. Also remove traces of old liquid gasket from the
mating surface of front timing chain case.
b. Apply a continuous bead of liquid gasket with tube presser [SST:
WS39930000] to mating surface of chain tensioner cover and
water pump cover.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
Attaching should be done within 5 minutes after coating.
c. Tighten mounting bolts.
5. Install water drain plug (front) on water pump side of cylinder block.

Apply liquid gasket to the thread of water drain plug (front).
Use Genuine Liquid Gasket or equivalent.
6. Install in the reverse order of removal in this step.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using radiator cap tester adapter [SST: EG17650301] and radiator cap
tester (commercial service tool). Refer to CO-34, "
LEAK CHECK" .

Start and warm up engine. Visually check if there is no leaks of engine coolant.

CVT FLUID

9. Check CVT fluid condition.

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" .
Changing CVT FluidBCS001FY
1. Warm up CVT fluid by driving the vehicle for 10 minutes.

Radiator (2)

CVT fluid cooler hose [inlet side (3)]

Transaxle assembly (4)
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.

FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15 × 25 mm (0.59 × 0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not available through NISSAN Parts Department, can also be used to repair squeaks
and rattles.
UHMW(TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note: Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingBIS0011B
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. Cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks to
repair the noise.
