HOW TO USE THIS MANUAL
E5U000000000E01
Range of Topics
• This manual contains procedures for performing all required service operations. The procedures are divided
into the following five basic operations:
— Removal/Installation
— Disassembly/Assembly
— Replacement
— Inspection
— Adjustment
• Simple operations which can be performed easily just by looking at the vehicle (i.e., removal/installation of
parts, jacking, vehicle lifting, cleaning of parts, and visual inspection) have been omitted.
Service Procedure
Inspection, adjustment
• Inspection and adjustment procedures are
divided into steps. Important points regarding the
location and contents of the procedures are

Repair procedure
1. Most repair operations begin with an overview illustration. It identifies the components, shows how the parts fit
together, and describes visual part inspection. However, only removal/installation procedures that need to be
performed methodically have written instructions.
2. Expendable parts, tightening torques, and symbols for oil, grease, and sealant are shown in the overview
illustration. In addition, symbols indicating parts requiring the use of special service tools or equivalent are also
shown.
3. Procedure steps are numbered and the part that is the main point of that procedure is shown in the illustration
with the corresponding number. Occasionally, there are important points or additional information concerning a
procedure. Refer to this information when servicing the related part.

Conversion to SI Units (Système International d'Unités)
• All numerical values in this manual are based on SI units. Numbers shown in conventional units are converted
from these values.
Rounding Off
• Converted values are rounded off to the same number of places as the SI unit value. For example, if the SI unit
value is 17.2 and the value after conversion is 37.84, the converted value will be rounded off to 37.8.
Upper and Lower Limits
• When the data indicates upper and lower limits, the converted values are rounded down if the SI unit value is
an upper limit and rounded up if the SI unit value is a lower limit. Therefore, converted values for the same SI
unit value may differ after conversion. For example, consider 2.7 kgf/cm
210—260 kPa {2.1—2.7 kgf/cm
270—310 kPa {2.7—3.2 kgf/cm
• The actual converted values for 2.7 kgf/cm
2
, 30—38 psi}
2
, 39—45 psi}
2
are 264 kPa and 38.4 psi. In the first specification, 2.7 is used as
2
in the following specifications:
an upper limit, so the converted values are rounded down to 260 and 38. In the second specification, 2.7 is
used as a lower limit, so the converted values are rounded up to 270 and 39.

GENERAL INFORMATION
FUNDAMENTAL PROCEDURES
Preparation of Tools and Measuring Equipment
• Be sure that all necessary tools and measuring
equipment are available before starting any work.
Special Service Tools
• Use special service tools or equivalent when they
are required.
E5U000000000E03
CHU0014W003
49 SE01 310
Disassembly
• If the disassembly procedure is complex,
requiring many parts to be disassembled, all parts
should be marked in a place that will not affect
their performance or external appearance and
identified so that reassembly can be performed
easily and efficiently.
Inspection During Removal, Disassembly
• When removed, each part should be carefully
inspected for malfunction, deformation, damage
and other problems.

WGIWXX0028E
GENERAL INFORMATION
Arrangement of Parts
• All disassembled parts should be carefully
arranged for reassembly.
• Be sure to separate or otherwise identify the parts
to be replaced from those that will be reused.
Cleaning of Parts
• All parts to be reused should be carefully and
thoroughly cleaned in the appropriate method.
Warning
• Using compressed air can cause dirt and
other particles to fly out causing injury to
the eyes. Wear protective eye wear
whenever using compressed air.
00–00
WGIWXX0029E
Reassembly
• Standard values, such as torques and certain
adjustments, must be strictly observed in the
reassembly of all parts.
• If removed, the following parts should be replaced
with new ones:
— Oil seals
— Gaskets
— O-rings
— Lockwashers
— Cotter pins
— Nylon nuts
• Depending on location:
— Sealant and gaskets, or both, should be
applied to specified locations. When sealant
is applied, parts should be installed before
sealant hardens to prevent leakage.
— Oil should be applied to the moving
components of parts.
— Specified oil or grease should be applied at
the prescribed locations (such as oil seals)
before reassembly.
Adjustment
• Use suitable gauges and testers when making
adjustments.

GENERAL INFORMATION
Rubber Parts and Tubing
• Prevent gasoline or oil from getting on rubber
parts or tubing.
Hose Clamps
• When reinstalling, position the hose clamp in the
original location on the hose and squeeze the
clamp lightly with large pliers to ensure a good fit.
WGIWXX0034E
Torque Formulas
• When using a torque wrench-SST or equivalent
combination, the written torque must be
recalculated due to the extra length that the SST
or equivalent adds to the torque wrench.
Recalculate the torque by using the following
formulas. Choose the formula that applies to you.
Torque Unit Formula
N·m N·m × [L/(L+A)]
kgf·m kgf·m × [L/(L+A)]
kgf·cm kgf·cm × [L/(L+A)]
ft·lbf ft·lbf × [L/(L+A)]
in·lbf in·lbf × [L/(L+A)]
A : The length of the SST past the torque wrench drive.
L : The length of the torque wrench.
Vise
• When using a vise, put protective plates in the
jaws of the vise to prevent damage to parts.

GENERAL INFORMATION
Inspection
• When a tester is used to inspect for continuity or
measuring voltage, insert the tester probe from
the wiring harness side.
• Inspect the terminals of waterproof connectors
from the connector side since they cannot be
accessed from the wiring harness side.
Caution
• To prevent damage to the terminal, wrap
a thin wire around the tester probe before
inserting into terminal.

ENGINE MOUNTING/DISMOUNTING
1. Install the SSTs (arms) to the cylinder block holes
as shown, and hand-tighten the bolts (part No.:
9YA20-1003) or M10 × 1.5T length 90 mm {3.55
in}.
2. Assemble the SSTs (bolts, nuts and plate) to the
specified positions.
3. Adjust the SSTs (bolts) so that less than 20 mm
{0.79 in} of thread is exposed.
4. Make the SSTs (arms and plate) parallel by
adjusting the SSTs (bolts and nuts).
5. Tighten the SSTs (bolts and nuts) to affix the
SSTs firmly.
Warning
• Self-locking brake system of the engine
stand may not be effective when the
engine is held in an unbalanced position.
This could lead to sudden, rapid
movement of the engine and mounting
stand handle and cause serious injury.
Never keep the engine in an unbalanced
position, and always hold the rotating
handle firmly when turning the engine.

6. Mount the engine on the SST (engine stand).
7. Drain the engine oil into a container.
8. Install the oil pan drain plug.
• With washer
1. Install the oil pan drain plug with a new washer.
Tightening torque
30—41 N·m {3.1—4.1 kgf·m, 23—30 ft·lbf}
• Without washer
1. Inspect the seal rubber of the oil pan drain plug and make sure there are no cracks or damage.
— If necessary, replace the oil pan drain plug.
2. Clean the flange surface (seal rubber) on the oil pan drain plug, then install the oil pan drain plug.
Tightening torque
22—30 N·m {2.2—3.1 kgf·m, 16—22 ft·lbf}
DISMOUNTING
• Dismount in the reverse order of mounting.
