PRECAUTIONS
CAUTION:
●Do not use home heating oil, gasoline or other alternate fuels in your diesel engine. The use of
those can cause engine damage.
●Do not use summer fuel at temperatures below –7°C (20°F). The cold temperatures will cause wax
to form in the fuel. As a result, it may prevent the engine from running smoothly.
●Do not add gasoline or other alternate fuels to diesel fuel.
Precautions for Multiport Fuel Injection System or Engine Control SystemEAS000FT
●Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
●Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
●Be careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Turbocharger (If Equipped)EAS000FU
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean sup-
ply of oil flowing through the turbocharger and to follow all required
maintenance instructions and operating procedures.
●Always use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
●Avoid accelerating engine to a high rpm immediately after start-
ing.
●If engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting if off.
Precautions for HosesEAS000FV
HOSE REMOVAL AND INSTALLATION
●To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.
●To reinstall the rubber hose securely, make sure that hose inser-
tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)

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.

WARNING:
To avoid the danger of being scalded, never drain the coolant when the engine is hot.
1. Disconnect mass air flow sensor harness connector from mass air flow sensor and clamp.
2. Release fuel pressure. Refer to EC-775, "
FUEL PRESSURE RELEASE" [QR20DE (WITH EURO-OBD)],
EC-1139, "
FUEL PRESSURE RELEASE" [QR20DE (WITHOUT EURO-OBD)], EC-42, "FUEL PRES-

3. Align center to insert quick connector straightly into fuel tube.
●Insert fuel tube into quick connector until the first spool on fuel
tubes is inserted completely and the second one is positioned
slightly below the quick connectors bottom end.
CAUTION:
●Hold A position in illustration when inserting fuel tube
into quick connector.
●Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
●Insert until you hear a “click” sound and actually feel
the engagement.
●To avoid misidentification of engagement with a similar sound, be sure to perform the next
step.
4. Before clamping fuel hose with hose clamps, pull quick connector hard by hand holding A position. Make
sure it is completely engaged (connected) so that it does not come out from fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
5. Install quick connector cap on quick connector joint.
●Direct arrow mark on quick connector cap to upper side.
6. Install fuel hose to hose clamp.
Connecting Quick Connector of Fuel Hose (Vehicle side)
Install quick connector as follows.
1. Make sure no foreign substances are deposited in and around tube and quick connector and no damage
on them.
2. Align center to insert quick connector straightly into fuel tube.
●Insert fuel tube until a click is heard.
●Install quick connector cap on quick connector joint. Direct
arrow mark on quick connector cap to upper side.
3. Install fuel hose to hose clamp.
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.
1. Apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped). Then check for fuel
leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections.
NOTE:
Use mirrors for checking on invisible points.
CAUTION:
Do not touch the engine immediately after stopped as engine becomes extremely hot.
