Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.

OPERATION PROCEDURE

Connect both battery cables.

NOTE:
Supply power using jumper cables if battery is discharged.

Use the Intelligent Key or mechanical key to turn the ignition switch to the

″

ACC

″

position. At this time, the

steering lock will be released.

Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.

Perform the necessary repair operation.

When the repair work is completed, return the ignition switch to the

″

LOCK

″

position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

Perform a self-diagnosis check of all control units using CONSULT-II.

Precautions for Drain Engine Coolant and Engine Oil

ABS00A7M

Drain engine coolant and engine oil when the engine is cooled.

Precautions for Disconnecting Fuel Piping

ABS00A7N

●

Before starting work, make sure no fire or spark producing items are in the work area.

●

Release fuel pressure before disconnecting and disassembly.

●

After disconnecting pipes, plug openings to stop fuel leakage.

Precautions for Removal and Disassembly

ABS00A7O

●

When instructed to use SST, use the specified tools. Always be careful to work safely, avoid forceful or
uninstructed operations.

●

Exercise maximum care to avoid damage to mating or sliding surfaces.

PRECAUTIONS

Revision: 2005 August

2005 Murano

●

Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
make sure that dowel pins are installed in the original position.

●

Cover openings of engine system with a tape or the equivalent, if necessary, to seal out foreign materials.

●

Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.

●

When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be
used in the step.

Precautions for Inspection, Repair and Replacement

ABS00A7P

Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.

Precautions for Assembly and Installation

ABS00A7Q

●

Use torque wrench to tighten bolts or nuts to specification.

●

When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.

●

Replace with new gasket, packing, oil seal or O-ring.

●

Dowel pin are used for several parts alignment, when replacing and reassembling parts with dowel
pins,makesure that dowel pins are installed in the original position.

●

Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.

●

Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.

●

Release air within route when refilling after draining engine coolant.

●

After repairing, start the engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.

Precautions for Angle Tightening

ABS00A7R

●

Use the angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:

–

Cylinder head bolts

–

Main bearing cap bolts

–

Connecting rod cap bolts

–

Crankshaft pulley bolt

●

Do not use a torque value for final tightening.

●

The torque value for these parts are for a preliminary step.

●

Ensure thread and seat surfaces are clean and coated with engine oil.

Precautions for Liquid Gasket

ABS00A7S

REMOVAL OF LIQUID GASKET SEALING

●

After removing mounting nuts and bolts, separate the mating
surface using the seal cutter [SST] and remove old liquid gasket
sealing.

CAUTION:

Be careful not to damage the mating surfaces.

●

Tap the seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

●

In areas where the seal cutter is difficult to use, use a plastic
hammer to lightly tap the parts, to remove it.

CAUTION:

If for some unavoidable reason tool such as a screwdriver
is used, be careful not to damage the mating surfaces.

LIQUID GASKET APPLICATION PROCEDURE

Using a scraper, remove old liquid gasket adhering to the gasket
application surface and the mating surface.

●

Remove liquid gasket completely from the groove of the gas-
ket application surface, mounting bolts, and bolt holes.

Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

Attach liquid gasket tube to the tube presser [SST: WS39930000
(

—

)].

Use Genuine RTV Silicone Sealant or equivalent. Refer to

Apply liquid gasket without breaks to the specified location with
the specified dimensions.

●

If there is a groove for liquid gasket application, apply liquid
gasket to the groove.

●

As for bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of this manual.

●

Within 5 minutes of liquid gasket application, install the mating
component.

●

If liquid gasket protrudes, wipe it off immediately.

●

Do not retighten mounting bolts or nuts after the installation.

●

After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.

CAUTION:

If there are specific instructions in this manual, observe
them.
