INSPECTION AFTER REMOVAL
Thermostat
lPlace a string so that it is caught in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.
lThe valve opening temperature is the temperature at which the
valve opens and falls from the thread.
lContinue heating. Check the full-open lift amount.
lAfter checking the full-open lift amount, lower the water temper-
ature and check the valve closing temperature.
Standard values
lIf out of the standard, replace thermostat.
INSTALLATION
Note the following, and install in the reverse order of removal.
lSecurely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.
lWhen inserting heater feed pipe end into cylinder head, apply a neutral detergent to O-ring. Then insert it
immediately.

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.
