[QR]PRECAUTIONSPFP:00001
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.
Dowel pins are used for several parts alignment. When replacing and reassembling with dowel pins, make
sure that dowel pins are installed in the original portion.
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 make sure there are no leaks at fuel line connections.
After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust systems for leakage.
Parts Requiring Angle TighteningEBS00KN5
Use an angle wrench (special service tool: KV10112100) 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 angle
tightening)
–Balancer unit
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.

PRECAUTIONS
Precautions for Liquid GasketEBS00MRW
REMOVAL OF LIQUID GASKET
After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter (special service tool) and remove the
old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
Tap seal cutter to insert it (1), and then slide it (2) by tapping on
the side as shown in the figure.
In areas where seal cutter is difficult to use, use plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser (special service
tool).
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
As for the bolt holes, normally apply the liquid gasket inside
the holes. Occasionally, it should be applied outside the
holes. Make sure to read the text of service manual.
Within five minutes of liquid gasket application, install the mat-
ing component.
If the liquid gasket protrudes, wipe it off immediately.
Do not retighten mounting bolts or nut after the installation.
Wait 30 minutes or more after installation before refilling
engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.

DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00KN7
WARNING:
Be sure to perform this step when the engine is stopped.
Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use
range (between three line notches on moving side).
NOTE:
Check the drive belt auto-tensioner indication when the engine is cold.
When new drive belt is installed, the indicator (notch on fixed side) should be within the range “a” in the
figure.
Visually check entire drive belt for wear, damage or cracks.
If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
Tension AdjustmentEBS00KN8
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationEBS00KN9
REMOVAL
1. Remove splash guard on RH undercover.
2. Hold the hexagonal part in center of drive belt auto-tensioner
pulley with a box wrench securely. Then move the wrench han-
dle in the direction of arrow (loosening direction of tensioner).
CAUTION:
Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.
Do not loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Do not turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pul-
ley.
3. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole of the retaining boss to fix drive belt auto-tensioner pulley.
4. Loosen drive belt from water pump pulley in sequence, and remove it.
