ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If the engine is already started,
stop it and allow 15 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE

Check engine oil for white turbidity or heavy contamination.

If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for oil leakage around the following area.

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Intake valve timing control cover

Intake valve timing control solenoid valve

Front cover

Chain tensioner cover

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:

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

Oil pressure check should be done in “Parking position”.
1. Check engine oil level. Refer to LU-25, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.

Removal and InstallationABS006J7
REMOVAL
1. Remove front cover. Refer to EM-196, "TIMING CHAIN" .
2. Remove the oil pump drive spacer.

Set bolts in the two bolt holes [M6 × pitch 1.0 mm (0.04 in)] on
the front surface. Using suitable puller, pull oil pump drive
spacer off from crankshaft.
NOTE:
The dimension between the centers of the two bolt holes is 33
mm (1.30 in).
In the figure, a commercial steering puller is used.
3. Remove oil pump.
INSTALLATION
1. Install the oil pump.
2. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank-
shaft key and the two flat surfaces of oil pump inner rotor.

If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi-
tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
3. Install in the reverse order of removal after this step.
1. Oil pump body 2. Oil pump outer rotor 3. Oil pump inner rotor
4. Oil pump cover 5. Oil pump drive spacer 6. Regulator valve
7. Regulator valve spring 8. Regulator valve plug

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.

PERIODIC MAINTENANCE
Revision: 2004 November 2004 FX35/FX45
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.

Revision: 2004 November 2004 FX35/FX45
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.
