"REMOVAL AND INSTALLATION" (A/T models).
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting
insulator.

When installation directions are specified, install parts according to the direction marks on them referring
to figure of components. Refer to EM-85, "
Removal and Installation (4WD Models)" .

Make sure that each mounting insulator is seated properly, and tighten mounting bolts and nuts.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

PRECAUTIONS

[YD22DDTi]PRECAUTIONSPFP:00001
Precautions for Draining Engine CoolantEBS00LQZ
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS00LR0

Before starting work, make sure no fire or spark producing items are in the work area.

After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyEBS00LR1

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 ReplacementEBS00LR2
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationEBS00LR3

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 liquid gasket, packing, oil seal or O-ring.

Dowel 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.

Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine 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, engine oil sliding surfaces well.

Release air within route when refilling after draining coolant.

After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust systems for leakage.
Parts Requiring Angle TighteningEBS00LR4

Use an angle wrench (special service tool: 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)

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 For Liquid GasketEBS00ODW
REMOVAL OF LIQUID GASKET

After removing the mounting bolts and nuts, separate the mating
surface using the 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 the 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. If specified, it should be applied outside the holes.
Make sure to read the instruction in this 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 after the installation.

After 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.

DRIVE BELTS

DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00LRA

Before inspecting engine, make sure engine has cooled down;
wait approximately 30 minutes after engine has been stopped.

Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.

Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentEBS00LRB

Adjust belts with the parts shown below.
CAUTION:

When a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.

If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid vari-
ation in deflection between pulleys.

Make sure the belts are fully fitted into the pulley grooves during installation.

Handle with care to avoid smearing the belts with engine oil or engine coolant.

Do not twist or bend the belts with strong force.
