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.

Changing Engine CoolantELS001JQ
WARNING:
lTo avoid being scalded, do not change engine coolant when engine is hot.
lWrap a thick cloth around cap and carefully remove radiator cap. First, turn radiator cap a quarter
of a turn to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and
remove radiator cap.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
When draining all engine coolant in the system, also perform the following steps.
2. Remove air relief plug (1) on heater feed tube.

4. Remove reservoir tank, drain engine coolant, then clean reservoir tank.
5. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush engine cooling system. Refer toMA-21, "
