CONNECTING ROD CAP BOLT OUTER DIAMETER
• Measure the outer diameter “d” at position as shown.
• If reduction appears in a position other than “d”, regard it as “d”.
• When “d” falls below the limit (when it becomes thinner), replace connecting rod cap bolt with a new one.

5. When the repair work is completed, return the ignition switch to the
″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Procedur e without Cowl Top Cover INFOID:0000000004307110
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
Precaution for Drain Coolant INFOID:0000000004307112
• Drain coolant when engine is cooled.
Precaution for Disco nnecting Fuel Piping INFOID:0000000004307113
• 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.
Precaution for Removal and Disassembly INFOID:0000000004307114
• When instructed to use special service tools, use the spec ified 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 equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and 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 specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and Replacement INFOID:0000000004307115
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and Installation INFOID:0000000004307116
• 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 specified,
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 after draining coolant.
• Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped). Then make 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. PIIB3706J

PRECAUTIONS
Parts Requiring Angular Tightening INFOID:0000000004307117
• Use an angle wrench for the final tightening of the following engine parts:
- Cylinder head bolts
- Camshaft sprocket (INT)
- 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 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.
Precaution for Liquid Gasket INFOID:0000000004307118
REMOVAL OF LIQUID GASKET SEALING
• After removing the bolts and nuts, separate the mating surface and remove the sealant using Tool.
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to
lightly tap (1) the cutter where the RTV Silicone Sealant is applied.
Use a plastic hammer to slide the cutter (2) by tapping on the side.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old Silicone RTV Sealant adhering to the gasket application surface and the mating surface.
• Remove the sealant completely from the groove of the gasket application surface, bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the sealant t ube to the tube presser.
Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-42, " Recommended Chemical
Product and Sealant " .
4. Apply the sealant without breaks to the specified location using Tool.
• If there is a groove for the s ealant application, apply the seal-
ant to the groove.
• As for the bolt holes, normally apply the sealant inside the holes. If specified, it should be applied outside the holes. Make
sure to read the text of this manual.
• Within five minutes of the seal ant application, install the mat-
ing component.
• If the sealant protrudes, wipe it off immediately.
• Do not retighten after the installation. Tool number : KV10112100 (BT-8653-A)
