NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged or if the auto belt tensioner reading (only for VK45DE engine) reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.

NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. Using automatic transmission fluid other than Genuine NISSAN Matic J
ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmis-
sion, which is not covered by the INFINITI new vehicle limited warranty.
(2) Refer to “Tire rotation” under the “General maintenance” heading earlier in this section.

SAE Viscosity NumberALS000G9
GASOLINE ENGINE OIL
SAE 5W-30 viscosity oil is preferred for all temperatures. SAE
10W-30 and 10W-40 viscosity oil may be used if the ambient
temperature is above -18°C (0°F)
Anti-Freeze Coolant Mixture RatioALS000GA
The engine cooling system is filled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/ Coolant or equivalent with the
proper mixture ratio of 50% anti-freeze and 50% demineralized
water/distilled water.
Other types of coolant solutions may damage your cooling sys-
tem.

ENGINE MAINTENANCE (VQ35DE ENGINE)PFP:10001
Checking Drive BeltsALS000H0
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 the belt mid-
way between pulleys.

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

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

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

Adjust if belt deflection exceeds the limit or if belt tension is not within specifications.
CAUTION:

When checking belt deflection or 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 deflection or tension without looseness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on the belt.
Tension AdjustmentALS000H1
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 of used belt”.

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.

Changing Engine CoolantALS000H2
WARNING:

To avoid being scalded, never change engine coolant when engine is hot.

Wrap a thick cloth around cap and carefully remove cap. First, turn cap a quarter of a turn to
release built-up pressure. Then turn cap all the way.
DRAINING ENGINE COOLANT
1. Remove front engine undercover with power tools.
2. Open radiator drain plug at the bottom of radiator, and remove
radiator cap.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
When drain all of engine coolant in the system, open water drain plugs on engine cylinder block.
Refer to EM-121, "
DISASSEMBLY" .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-17, "

If water drain plugs are removed, close and tighten them. Refer to EM-126, "
ASSEMBLY" .
2. Remove air relief plug on heater hose.
3. Fill radiator and reservoir tank to specified level.

Use Genuine NISSAN Long Life Antifreeze/ Coolant or
equivalent mixed with water (distilled or demineralized).
Refer to MA-12, "

CANTS".

Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2-1/8 US qt,1-3/4 lmp qt) a minute
to allow air in system to escape.

When engine coolant overflows air relief hole on heater hose,
install air relief plug with new O-ring.
4. Warm up engine to normal operating temperature with radiator cap installed.
5. Run engine at 3,000 rpm for 10 seconds and return to idle speed.

Repeat two or three times.
Watch engine coolant temperature gauge so as not to overheat engine.
6. Stop engine and cool down to less than approximately 50°C (122°F).

Cool down using a fan to reduce the time.

If necessary, refill radiator up to filler neck with engine coolant.
7. Refill reservoir tank to “MAX” level line with engine coolant.
8. Repeat steps 3 through 6 two or more times with radiator cap installed until engine coolant level no longer
drops.

Changing Engine OilALS000H3
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Remove front engine undercover with power tool.
2. Warm up engine, and check for engine oil leakage from engine components. Refer to LU-7, "
