INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).ItemReference page
Warning lamps and
chimesMake sure that all warning lamps and chimes are operating properly. —
Windshield wiper and
washerCheck that the wipers and washer operate properly and that the wipers do not
streak.—
Windshield defrosterCheck that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner.—
Steering wheelCheck that it has the specified play. Be sure to check for changes in the steer-
ing condition, such as excessive play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
SeatsCheck seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every
position. Check that the head restrains move up and down smoothly and that
the locks (if equipped) hold securely in all latched positions. Check that the
latches lock securely for folding-down rear seatbacks.—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage.MA-39
Accelerator pedalCheck the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal.—
BrakesCheck that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
boosterCheck the pedal for smooth operation and make sure it has the proper dis-
tance under it when depressed fully. Check the brake booster function. Be
sure to keep the floor mats away from the pedal.BR-6

RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and Lubricants NLS0007E
*1: For further details, see “Engine Oil Recommendation”.
*2: Using automatic transmission fluid other than genuine NISSAN Matic J ATF will cause deterioration in driveability and auto-
matic transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle
limited warranty.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0°C (32°F).
*4: Canada NISSAN Automatic Transmission Fluid or DEXRON
TM VI type ATF may also be used.

ENGINE MAINTENANCE (VQ35DE ENGINE)

ENGINE MAINTENANCE (VQ35DE ENGINE)PFP:10001
Checking Drive BeltsNLS0009Y
WARNING:
Be sure to perform when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on belt midway
between pulleys.

Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.

Measure the belt tension with belt tension gauge (Commercial
service tool: BT3373-F or equivalent) at points marked
shown in the figure.

When measuring the deflection, apply 98 N (10 kg, 22 lb) at
the marked point.

Adjust if the belt deflection exceeds the limit or if the belt ten-
sion is not within specifications.
CAUTION:

When checking the belt deflection or the tension immediately after installation, first adjust it to
the specified value. Then, after turning crankshaft two turns or more, re-adjust to the specified
value to avoid variation in deflection between pulleys.

Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.

CAUTION:

When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.

When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.

When checking belt deflection or tension immediately after installation, first adjust it to the speci-
fied value. Then, after turning crankshaft two turns or more, re-adjust to the specified value to
avoid variation in deflection between pulleys.

When installing belt, make sure that it is correctly engaged with pulley grooves.

Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.

Do not twist or bend belt excessively.
ALTERNATOR AND POWER STEERING OIL PUMP BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (A) and adjust tension by turning
adjusting bolt (B).

For the specified belt tension, refer to MA-14, "Checking Drive
Belts" .
3. Tighten nut (A).
A/C COMPRESSOR BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (C) and adjust tension by turning adjusting bolt (D).

For the specified belt tension, refer to MA-14, "Checking Drive Belts" .
3. Tighten nut (C).
Changing Engine CoolantNLS0007J
WARNING:

To avoid being scalded, do not change engine coolant when the engine is hot.

Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.

Be careful not to allow engine coolant to contact drive belts.
DRAINING ENGINE COOLANT
1. Remove engine room cover (RH and LH). Refer to EM-15, "ENGINE ROOM COVER" .
2. Remove air duct (inlet). Refer to EM-19, "
AIR CLEANER AND AIR DUCT" .
3. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.

ENGINE MAINTENANCE (VK45DE ENGINE)PFP:10001
Checking Drive BeltsNLS0007Q
WARNING:
Be sure to perform when the engine is stopped.

Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.

Remove front engine undercover with power tool when inspecting power steering oil pump belt.

Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range
(between three line notches).
NOTE:

Check auto tensioner indication when engine is cold.

When new drive belt is installed, the range should be “A”.

The indicator notch is located on the moving side of the tensioner for alternator, water pump and A/C
compressor belt, while it is found on the fixed side for power steering oil pump belt.

Visually check entire belt for wear, damage or cracks.

If the indicator is out of allowable working range or belt is damaged, replace belt.
Tension AdjustmentNLS0007R
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantNLS0007S
WARNING:

To avoid being scalded, do not change engine coolant when engine is hot.

Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.

Be careful not to allow engine coolant to contact drive belts.
DRAINING ENGINE COOLANT
1. Remove engine room cover (RH and LH) Refer to EM-173, "ENGINE ROOM COVER" .
2. Remove engine cover with power tool. Refer to EM-179, "
INTAKE MANIFOLD" .
3. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.

Checking Power Steering Fluid and LinesNLS0008E
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80°C (122 to 176°F)
or “COLD” range at fluid temperatures of 0 to 30°C (32 to 86°F).
CAUTION:

Do not overfill.

Recommended fluid is genuine NISSAN PSF or equivalent.
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .


Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.

Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsNLS0008F
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.

Shake each wheel to check for excessive play.

Check wheel bearings for smooth operation.

Check axle and suspension nuts and bolts for looseness.

Check strut (shock absorber) for oil leakage or other damage.

Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.
