Precautions for Drain Engine CoolantEBS00KN0
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS00KN1
●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 DisassemblyEBS00KN2
●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.
Precautions for Inspection, Repair and ReplacementEBS00KN3
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationEBS00MRZ
●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 oil or 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 coolant.
●Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine
stopped). Then mark sure that there are no leaks at fuel line connections.
●After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems
for leakage.
Parts Requiring Angular TighteningEBS00KN5
●Use an angle wrench for the final tightening of the following engine parts.
–Cylinder head bolts
–Lower cylinder block bolts
–Connecting rod cap bolts
–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.
