PRECAUTIONS
[YD22DDTi]PRECAUTIONSPFP:00001
Precautions for Drain CoolantEBS00BNO
lDrain coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS00BNP
lBefore starting work, make sure no fire or spark producing items are in the work area.
lRelease fuel pressure before disassembly.
lAfter disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyEBS00BNQ
lWhen instructed to use special service tools, 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 ReplacementEBS00BNR
lBefore repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way,
and replace if necessary.
Precautions for Assembly and InstallationEBS00BNS
lUse torque wrench to tighten bolts or nuts.
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 gasket, packing, oil seal or O-ring.
lThoroughly wash, clean, and air-blow each part. Carefully check oil or 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 after draining coolant.
lAfter repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems
for leakage.
Parts Requiring Angular TighteningEBS00BNT
lUse 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)
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.
