When inserting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
CAUTION:
Install protecting front oil seal lip section from any damage.
11. Tighten crankshaft pulley bolt with the following procedure.

Secure crankshaft pulley with pulley holder [SST: KV10109300], and tighten crankshaft pulley bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark on crankshaft pulley, mating with any one of six

d. Turn another 60 degrees clockwise (angle tightening).

Check the tightening angle with movement of one angle mark.
12. Install all removed parts in the reverse order of removal.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.

INSPECTION AFTER REMOVAL
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.
NOTE:
When replacing any cylinder head bolts, it is possible to use them
with mixing flange bolt and bolt with washer.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-102, "
CYLIN-
DER BLOCK DISTORTION" .
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with scraper.
CAUTION:
Use utmost care not to 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.Bolt with washer

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

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-14, "
RECOMMENDED 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
leakage 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
including 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. : 50.0 N·m (5.1 kg-m, 37 ft-lb)

Use alternator bracket mounting bolt holes for the front side.
2. Lift with hoist and secure engine in position.
3. Use manual lift table caddy (commercial service tool) or equiva-
lently rigid tool such as transmission jack. Securely support bot-
tom of front suspension member, and simultaneously adjust
hoist tension.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.
4. Separate RH engine mounting insulator and RH engine mounting bracket.
5. Pull LH engine mounting through-bolt out.
6. Remove front suspension member mounting nuts and bolts. Refer to FSU-5, "
FRONT SUSPENSION
ASSEMBLY" .
7. Remove engine and transaxle assembly with front suspension member from vehicle downward by care-
fully operating supporting tools.
CAUTION:

During the operation, make sure that no part interferes with vehicle side.

Before and during this lifting, always check if any harnesses are left connected.

During the removal operation, always be careful to prevent vehicle from falling off the lift due to
changes in the center of gravity.

If necessary, support vehicle by setting jack or equivalent tool at the rear.
8. Remove power steering oil pump with piping connected from engine. Refer to PS-29, "
POWER STEER-
ING OIL PUMP" .
9. Remove front engine mounting and rear engine mounting through-bolts to remove front suspension mem-
ber.
10. Remove starter motor. Refer to SC-14, "
STARTING SYSTEM" .
11. Remove each engine mounting insulator and each engine mounting bracket from engine, transaxle and
front suspension member.
12. Separate engine and transaxle. Refer to AT- 2 4 1 , "
TRANSAXLE ASSEMBLY" .
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting
insulator.

When installation directions are specified, install parts according to the direction marks on them referring
to the figure of components. Refer to EM-77, "
Removal and Installation" .

Make sure that each engine mounting insulator is seated properly, and tighten mounting nuts and bolts.Slinger bolts:
