PRECAUTIONS
PRECAUTIONS
PFP:00001
Precautions for Draining Engine CoolantEBS01E5H
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS01E5I
lBefore starting work, make sure no fire or spark producing items are in the work area.
lAfter disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyEBS01E5J
lWhen instructed to use SST, use the specified tools. Always be careful to work safely, avoid forceful or
uninstructed operations.
lExercise maximum care to avoid damage to mating or sliding surfaces.
lCover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
lMark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.
lWhen 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.
Precautions for Inspection, Repair and ReplacementEBS01E5K
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationEBS01E5L
lUsetorquewrenchtotightenboltsornutstospecification.
lWhen 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.
lReplace with new liquid gasket, packing, oil seal or O-ring.
lDowel 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.
lThoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
lAvoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
lRelease air within route when refilling after draining engine coolant.
lAfter repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust systems for leakage.
Parts Requiring Angle TighteningEBS01E5M
lUse an angle wrench [SST: KV10112100] 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 angle
tightening)
lDo not use a torque value for final tightening.
lThe torque value for these parts are for a preliminary step.
lEnsure thread and seat surfaces are clean and coated with engine oil.

Precautions For Liquid GasketEBS01E5N
REMOVAL OF LIQUID GASKET
lAfter removing the mounting bolts and nuts, separate the mating
surface using the seal cutter [SST] and remove the old liquid
gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
lTap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.
lIn areas where seal cutter [SST] is difficult to use, use plastic
hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as 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 liq-
uid gasket application surface and the mating surface.
lRemove the liquid gasket completely from the groove of the
liquid 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 [SST].
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
lIf there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
lAs for the bolt holes, normally apply the liquid gasket inside
the holes. If specified, it should be applied outside the holes.
Make sure to read the text of this manual.
lWithin five minutes of liquid gasket application, install the mat-
ing component.
lIf the liquid gasket protrudes, wipe it off immediately.
lDo not retighten mounting bolts or nuts after the installation.
lAfter 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.
