TIMING CHAIN
Revision: 2006 July 2007 FX35/FX45
f. Further tighten by 90 degrees. (Angle tightening)

Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns smoothly.
16. Install in the reverse order of removal after 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
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS"

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid. power steering fluid, brake fluid, etc.

REMOVAL
1. Remove the following parts:

Front engine undercover

Radiator; Refer to CO-41, "RADIATOR"

Drive belt; Refer to EM-174, "DRIVE BELTS" .

Cooling fan; Refer to CO-49, "COOLING FAN" .

Rear plate cover; Refer to EM-187, "OIL PAN AND OIL STRAINER" .
2. Remove crankshaft pulley as follows:
a. Set ring gear stopper (SST).
b. Loosen crankshaft pulley bolt, and then pull crankshaft pulley with both hands to remove it.
CAUTION:

Do not remove crankshaft pulley bolt. Keep loosened
crankshaft pulley bolt in place to protect removed crank-
shaft pulley from dropping.

Do not remove balance weight (inner hexagon bolt) at the
front of crankshaft pulley.
3. Remove front oil seal using suitable tool. CAUTION:
Be careful not to damage front cover and oil pump drive
spacer.
INSTALLATION
1. Apply new engine oil to both oil seal lip and dust seal lip of new front oil seal.
2. Install front oil seal.

CONSULT-II CHECKING SYSTEM
Revision: 2006 July 2007 FX35/FX45
Nickel Metal Hydride Battery Replacement NAS0006L
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if
mistreated. Do not recharge, disassemble or dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.
Checking Equipment NAS0006M
When ordering the following equipment, contact your NISSAN/INFINITI distributor.
CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.

If CONSULT-II CONVERTER is not connected with CONSULT-II, vehicle occur the “FAIL SAFE
MODE” which is “LIGHT UP the HEAD LIGHT” and/or “COOLING FAN ROTATING” when CON-
SULT-II is started.

Previous CONSULT-II “I” and “Y” DLC-I and DLC-II cables should NOT be used anymore because
their DDL connector pins can be damaged during cable swapping.
NOTE:

The CONSULT-II must be used in conjunction with a program card.
CONSULT-II does not require loading (Initialization) procedure.

Be sure the CONSULT-II is turned off before installing or removing a program card.
CONSULT-II Start ProcedureNAS0006N
NOTE:
Turning ignition switch off when performing CAN diagnosis could cause CAN memory to be erased.
1. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.
Tool name Description
NISSAN CONSULT-II
1. CONSULT-II unit (Tester internal soft: Resident
version 3.3.0) and accessories
2. Program card UED06D and AEN06B (For NATS)

AWD MODELS
INFINITI recommends that a dolly be used as illustrated when towing AWD models.
CAUTION:
Never tow AWD models with any of the wheels on the ground as this may cause serious and expen-
sive damage to the powertrain.
Vehicle Recovery (Freeing a Stuck Vehicle) NAS0006U
Securely install the vehicle recovery hook stored with jacking tools.
Make sure that the hook is properly secured in the stored place after
use.
WARNING:

Stand clear of a stuck vehicle.

Do not spin your tires at high speed. This could cause them
to explode and result in serious injury. Parts of your vehicle
could also overheat and be damaged.
CAUTION:

Tow chains or cables must be attached only to the vehicle
recovery hooks or main structural members of the vehicle.
Otherwise, the vehicle body will be damaged.

Do not use the vehicle tie downs to free a vehicle stuck in
sand, snow, mud, etc. Never tow the vehicle using the vehi-
cle tie downs or recovery hooks.

Always pull the cable straight out from the front of the vehi-
cle. Never pull on the hook at an angle.

Pulling devices should be routed so they do not touch any
part of the suspension, steering, brake or cooling systems.

Pulling devices such as ropes or canvas straps are not rec-
ommended for use in vehicle towing or recovery.
