PRECAUTIONS
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
Precaution for Drain Engine Coolant and Engine OilINFOID:0000000003802227
Drain engine coolant and engine oil when the engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000003802228
 Before starting work, check no fire or spark producing items are in the work area.
 Release fuel pressure before disconnecting and disassembly.
 After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000003802229
 When instructed to use SST, use the specified tools. Always be careful to work safely, avoid forceful or unin-
structed operations.
 Exercise maximum care to avoid damage to mating or sliding surfaces.
 Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
check that dowel pins are installed in the original position.
 Cover openings of engine system with a tape or the equivalent, if necessary, to seal out foreign materials.
 Mark and arrange disassembly parts in an organized way for easy troubleshooting and reassembly.
 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. Power tools may be used
in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000003802230
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000003802231
 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,
check 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, 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:0000000003802232
 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 angle
tightening)
 Never use a torque value for final tightening.
 The torque value for these parts are for a preliminary step.

Precaution for Liquid GasketINFOID:0000000003802233
REMOVAL OF LIQUID GASKET SEALING
 After removing mounting nuts and bolts, separate the mating sur-
f a c e u s i n g t h e s e a l c u t t e r [ S S T: K V 1 0 1111 0 0 ( J37228)] (A) and
remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
 Tap the seal cutter [SST: KV10111100 (J37228)] to insert it (B), and
then slide it (C) by tapping on the side as shown in the figure.
 In areas where the seal cutter [SST: KV10111100 (J37228)] is diffi-
cult to use, use a plastic hammer 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 (A), 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.
3. Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine Liquid Gasket or equivalent.
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. Check to
read the text of this manual.
 Within 5 minutes of liquid gasket application, install the mating
component.
 If liquid gasket protrudes, wipe it off immediately.
 Never 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 instructions in this manual, observe
them.

WARNING:
Be sure to perform the this step when engine is stopped.
 Check that the indicator (A) of drive belt auto-tensioner is within the possible use range (C).
NOTE:
 Check the drive belt auto-tensioner indication when the engine is cold.
 When new drive belt is installed, the indicator should be within the range (B) in the figure.
 Visually check entire drive belt for wear, damage or cracks.
 If the indicator is out of the possible use range or belt is damaged, replace drive belt.

3. 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 drive belt).
CAUTION:
 Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.
 Never loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Never turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pulley.
4. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole (A) of the retaining boss to
fix drive belt auto-tensioner pulley.
 Keep drive belt auto-tensioner pulley arm locked after drive belt is removed.
5. Loosen drive belt from water pump pulley in sequence, and remove it.
INSTALLATION
1. Hook drive belt on to all pulleys except for drive belt auto-tensioner pulley, and then onto drive belt auto-
tensioner pulley finally.
CAUTION:
 Confirm drive belt is completely set to pulleys.
 Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
2. Release drive belt auto-tensioner, and apply tension to drive belt.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm tension of drive belt at indicator is within the possible use range. Refer to EM-12, "
