PRECAUTIONS
PFP:00001
Precautions for Drain Engine Coolant
ABS004RJ
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel Piping
ABS004RK
●
Before starting work, make sure no fire or spark producing items are in the work area.
●
Release fuel pressure before disassembly.
●
After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and Disassembly
ABS004RL
●
When instructed to use special service tools, 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.
●
Cover openings of engine system with 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 where noted in the step.
Precautions for Inspection, Repair and Replacement
ABS004RM
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and Installation
ABS004RN
●
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.
●
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 engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust systems for leakage.
Parts Requiring Angular Tightening
ABS004RO
●
Use an angle wrench for the final tightening of the following engine parts:
–
Cylinder head bolts
–
Main bearing cap bolts
–
Connecting rod cap nuts
–
Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)
●
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
Revision; 2004 April
2003 Murano
Precautions for Liquid Gasket
ABS004RP
REMOVAL OF LIQUID GASKET SEALING
●
After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
●
In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating
surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1.
Using a scraper, remove the old liquid gasket adhering to the
gasket application surface and the mating surface.
●
Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2.
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.
3.
Attach the liquid gasket tube to the tube presser.
Use Genuine RTV silicone sealant or equivalent. Refer to
GI-46, "RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS"
4.
Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
●
If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
●
As for the bolt holes, normally apply the liquid gasket inside
the holes. Occasionally, it should be applied outside the
holes. Make sure to read the text of this manual.
●
Within five minutes of gasket application, install the mating
component.
●
If the liquid gasket protrudes, wipe it off immediately.
●
Do not retighten after the installation.
●
After 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe
them.
