Cylinder Head Bolts Outer Diameter
 Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.
 If reduction of outer diameter appears in a position other than “d2”,
use it as “d2” point.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-127, "
Cylinder
Block".
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Never allow gasket debris to enter passages for engine oil or engine coolant.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.
 If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gasket.
2. Tighten cylinder head bolts in numerical order as shown with the
following procedure to install cylinder head.
CAUTION:
If cylinder head bolts are re-used, check their outer diame-
ters before installation. Follow the “Cylinder Head Bolts
Outer Diameter” measurement procedure.
a. Apply new engine oil to threads and seating surfaces of mount-
ing bolts.
b. Tighten all bolts.
c. Completely loosen.
CAUTION:Limit (“d1”–“d2”): 0.15 mm (0.0059 in)

e. Turn all bolts 75 degrees clockwise (angle tightening).
CAUTION:
Check and confirm the tightening angle by using the angle
wrench [SST: KV10112100] (A) or protractor. Avoid judg-
ment by visual inspection without the tool.
f. Turn all bolts 75 degrees clockwise again (angle tightening).
3. Installation is in the reverse order of removal, for the remaining parts.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
 Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-19, "
Fluids and Lubricants".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
 Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
 Bleed air from lines and hoses of applicable lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.

ENGINE ASSEMBLY
4. Remove engine mounting insulator (RH) (1), engine mounting
bracket (RH) (2) and engine mounting stay (3).
5. Remove engine mounting through bolt-securing nut (A).
6. Carefully lower jack, or raise lift to remove the engine and the transaxle assembly.
CAUTION:
 Make sure that no part interferes with the vehicle side.
 Before and during this lifting, always check if any harnesses are left connected.
 During the removal, always be careful to prevent the vehicle from falling off the lift due to
changes in the center of gravity.
 If necessary, support the vehicle by setting jack or suitable tool at the rear.
Separation
1. Remove starter motor. Refer to STR-13, "Removal and Installation".
2. Lift with a hoist and separate the engine from the transaxle assembly. Refer to EM-89, "
Exploded View".
INSTALLATION
Installation is in the reverse order of removal.
 Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
 Make sure that each mounting insulator is seated properly, and tighten mounting nuts and bolts.
 Tighten engine mounting insulator (RH) bolts in the numerical
order shown.

Measure the inner diameter of piston pin hole with an inside
micrometer.
Piston Pin Outer Diameter
Measure the outer diameter of piston pin with a micrometer.
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pin hole diameter) – (Piston pin outer diameter)
 If oil clearance is out of the standard, replace piston and piston pin assembly.
PISTON RING SIDE CLEARANCE
 Measure the side clearance of piston ring and piston ring groove
with a feeler gauge.
 If the measured value exceeds the limit, replace piston ring, and
measure again. If it still exceeds the limit, replace piston also.
PISTON RING END GAP
 Make sure that cylinder bore inner diameter is within the specifica-
tion. Check "Cylinder Bore Inner Diameter".
 Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and measure
piston ring end gap with a feeler gauge.

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:0000000001337765
 Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000001337766
 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:0000000001337767
 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:0000000001337768
 Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000001337769
 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:0000000001337770
 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)
