PRECAUTIONS
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
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 all control units using CONSULT-II.
Precaution for Drain CoolantINFOID:0000000001527635
 Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000001527636
 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 DisassemblyINFOID:0000000001527637
 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 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. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000001527638
 Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000001527639
 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.
Parts Requiring Angular TighteningINFOID:0000000001527640
 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. Tool number : KV10112100 (BT-8653-A)

CheckingINFOID:0000000001381384
 Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
 Visually check belts for wear, damage, and cracks on inside and
edges.
 Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the
test.
 When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
 Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.
CAUTION:
 When the tension and frequency are measured, the acoustic tension gauge should be used.
 When checking immediately after installation, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection
between pulleys.
Tension AdjustmentINFOID:0000000001381385
CAUTION:
 When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
 When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
 When installing a belt, make sure it is correctly engaged with the pulley groove.
 Never allow oil or engine coolant to get on the belt.
 Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position
with the specified torque by 45 degrees.

 Thickness of new valve lifter (B) can be identified by stamp
mark (A) on the reverse side (inside the cylinder).
 Stamp mark “300” indicates 3.00 mm (0.118 in) in thickness.
NOTE:
Available thickness of valve lifter: 26 sizes range 3.00 to 3.50 mm (0.1181 to 0.1378 in) in steps of 0.02
mm (0.0008 in) (when manufactured at factory). Refer to EM-123, "
Camshaft".
5. Install the selected valve lifter.
6. Install camshaft. Refer to EM-59, "
Exploded View".
7. Manually rotate crankshaft pulley a few rotations.
8. Make sure that valve clearances for cold engine are within specifications by referring to the specified val-
ues.
9. Install all removed parts in the reverse order of removal.
10. Warm up the engine, and check for unusual noise and vibration.

COMPRESSION PRESSURE
COMPRESSION PRESSURE
InspectionINFOID:0000000001381392
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-377, "
Inspection" (EURO-OBD), EC-681, "Inspection" (WITHOUT
EURO-OBD).
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-47, "
Exploded View".
4. Connect an engine tachometer (not required in use of CONSULT-III).
5. Install a compression tester (B) with an adapter (commercial
service tool) (A) onto spark plug hole.
 Use the adapter whose picking up end inserted to spark plug
hole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
6. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge
pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
CAUTION:
Always use fully a changed battery to obtain the specified engine speed.
 If the engine speed is out of the specified range, check battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
 If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.
 If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-
functioning. Check valves for damage. Replace valve or valve seat accordingly.
 If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.
7. After inspection is completed, install removed parts.
8. Start the engine, and confirm that the engine runs smoothly.
9. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-469, "
Description".
