Precaution for Assembly and InstallationINFOID:0000000001325697
 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.
 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 re move foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
 Release air within route when refilling after draining engine coolant.
 After repairing, start the engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.
Precaution for Angle TighteningINFOID:0000000001325698
 Use the angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
- Cylinder head bolts
- Main bearing cap bolts
- Connecting rod cap bolts
- Crankshaft pulley bolt (No the angle wrench is required as bolt flange is provided with notches for angletightening)
 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 GasketINFOID:0000000001325699
REMOVAL OF LIQUID GASKET SEALING
 After removing mounting nuts and bolts, separate the mating sur- face using the seal cutter (SST) and remove old liquid gasket seal-
ing.
CAUTION:
Be careful not to damage the mating surfaces.
 Tap the seal cutter to insert it, and then slide it by tapping on the side as shown in the figure.
 In areas where the seal cutter is difficult to use, use a plastic ham-
mer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as a screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove old liquid gasket adhering to the gasket application surface and the mating surface.
 Remove liquid gasket completely from the groove of the gas-
ket 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.

PRECAUTIONS
3. Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44
.
4. Apply liquid gasket without breaks to the specified location with the specified dimensions.
 If there is a groove for liquid gasket application, apply liquid
gasket to the groove.
 As for bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes. Make
sure to read the text of this manual.
 Within five minutes of liquid gasket application, install the mat-
ing component.
 If liquid gasket protrudes, wipe it off immediately.
 Do not retighten mounting bolts or nuts after the installation.
 After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
CAUTION:
If there are specific instruct ions in this manual, observe
them.

AIR CLEANER AND AIR DUCT
INSTALLATION
Note the following, and install in the reverse order of removal.
 Align marks. Attach each joint. Screw clamps firmly.
 To position air cleaner case, refer to
EM-18, "
Changing Air Cleaner Filter".
Changing Air Cleaner FilterINFOID:0000000001325709
INSPECTION
Check status (fouling, damage, etc.) of air cleaner filter at power duct
hole.
REMOVAL
Removal in the order below.
1. Remove air duct (inlet) from air cleaner case.
2. Disconnect harness connector from mass air flow sensor.
3. Loosen clamp bolts of air hose.
4. Remove mounting bolts for air cleaner case. Remove air cleaner
case/mass air flow sensor/air hose assembly.
5. Unhook clips and open air cleaner case, and remove air cleaner filter.
INSTALLATION
Note the following, and install in the reverse order of removal.
 If grommet at bottom of air cleaner case comes off together with air
cleaner case, fix it to vehicle before installation.
 Look at internal bottom face through power duct hole, and position air cleaner case with resonator upper end circle and air cleaner
case round hole aligned. Then push air cleaner case straight
down.
 At this time, check by hand if protrusion at bottom of air cleaner
case has been inserted into grommet on vehicle side.
 Clip power duct with bulge on reverse side of lower end engaged with air cleaner case.
